The resulting liquid is then extruded from a spinneret, cooled with water, stretched on rollers, and wound into cloth.

A recent competitor to Kevlar is Spectra Shield. Unlike Kevlar, Spectra Shield is not woven but rather spun into fibers that are then laid parallel to each other. The fibers are coated with resin and layered to form the cloth. After the cloth is made, it must be cut into the proper pattern pieces. These pieces are then sewn together with accessories such as straps to form the finished vest. Other articles you might like:. User Contributions: 1. I would like to know if someone knows about this type of project.

I can design but I would like to know better the materials that I have to use when I make the vest. An were I can buy it or find it what store. Thank you in advance. Ballistic armour plates are strong and durable, offering increased protection to the wearer. These vests are designed to be worn in high-risk situations, this includes military and tactical teams, among others. These vests are available in a multitude of colours, like all our vests, and worn over clothing.

Bulletproof Undercover SAB undercover vests offer level II protection, the same resistance against shots fired from handguns as our other Kevlar vests. They are discretely designed to be worn with formal clothing, providing protection without looking conspicuous.

Nothing is bulletproof, not even a manhole cover. The bullet could have a serrated edge or something similar to it. Bulletproof vests do not make the wearer become Superman. The material will stop a bullet similar to how a net will stop a tennis ball or volleyball. It causes the bullet to turn, slow it down and send its energy through the whole panel.

The bullet mushrooms, which helps in the process. Keep in mind that the slower the bullet is, the better off the wearer is going to be. Bullets that have a hard tip or fired at a high velocity will get through the fibers and right through the bullet proof vest.

However, any bullet — small or large — that travels at a high rate of speed will get through body armor. Huge handgun rounds such as. Important: The shells of a shotgun are very dangerous to bulletproof vests wearers because vests Bulletproof Vest - CRU - Da Dirty 30 (Cassette not rated for these kinds of bullets. The reason? Shot shells do not have a consistent velocity. Some thoughts that popped into my head while I was searching for my copy of Rhythm Blunt Cru's first and only album, Da Dirty 30 : -When I first heard about the project thanks to The SourceI believe, but don't hold me to thatI assumed that Cru was a fake group, and the album was just a concept album that featured other rappers playing roles not unlike what Prince Paul would later do with his hip hop opera A Prince Among Thievesthanks to the early word that rappers as diverse as Black Rob, Slick Rick, and Ras Kass would appear.

Even with this evidence, I still wasn't convinced that Cru was a real group. In no way should that last sentence be construed as any sort of comparison between Public Enemy and Cru.

Unlike most modern-era rap albums, Da Dirty 30 is produced in its entirety by Yogi, and this allows a consistent sound to shine through. Yogi seems to have a preference for that old New York boom bap, and his beats go a long way toward bringing that nostalgic feeling back, even if he mixes in a little of the flavor of the day for good measure Bad Boy was a popular record label inand the inclusion of both Black Rob and The Lox are far from accidental.

You shouldn't go into Bulletproof Vest - CRU - Da Dirty 30 (Cassette CD believeing that it will be filled with sociopolitical rants, Buddhist chants, and spoken word poetry, though: as was the standard at the time, Da Dirty 30 is filled with tales of violence, some remorse regarding said violence, treatment of women as objects, and multiple attempts at humor most of which fail.

Hell, one of the songs actually stops midway through to present an unnamed woman blowing a guy. The only track that attempts something resembling a commentary is the final song, "Armageddon", which discusses the ramifications of rap beef, or as I like to call it, when keeping it real goes wrong.

A brief appearance on a Violator Records compilation album can be easily explained away as a studio outtake, although it's not like I work for Violator, so I may just be talking out of my ass. Because of this career move, there isn't a lot known about the Rhythm Blunt Cru and the three men who swooped in to contribute to the cause of great hip hop music. Yogi is still producing music, and landed two tracks on Method Man's Tical 0: The Prequelbut as any Wu-Tang fan will tell you, that shouldn't be seen as any kind of accomplishment.

Also, every time I hear the word "footlong", I think of the episode of The Simpsons where Ned Flanders's wife is killed by an overexcited cheerleader with a T-shirt gun. Is that just me? Nice thumping beat, simple and effective. Haven't heard from Antoinette in a while, so this was a pleasant surprise. I do question sequencing a song that features multiple guests as the first real song on your debut album, especially when you're a rap group that nobody actually knowsmaking it even harder to distinguish who's who.

But that's just me, I tend to make sense. The rappers aren't the best, but the sound decent enough over Yogi's instrumental. And I don't actually think Yogi sounds like Q-Tip, but I can see where the similarities can be found. The chilled-out beat is good to relax to, but you should track down the remix, which finds room for some drums over the original instrumental.

What the fuck? He sounds better on here than he did on his entire debut album. Too bad the beat is wasted on the other rappers featured. While I appreciate the fact that Yogi has actually heard of Portishead, since he uses their "Sour Times" as a foundation for this song, truth be told Inspectah Deck did a better job of sampling Portishead on "Kiss Of The Black Widow" from the first Bobby Digital album, and all he did there was loop nine seconds of "Only You" repeatedly.

This song sounds terrible. The blow job interlude came out of left field, but that I looked at the title of the song again, so I suppose the joke's on me. This one-verse wonder Album) not bad at all.

Black Rob and Cru pass the mic around the room, and while they never fulfill the promise of a Boot Camp Clik homage that the title would otherwise indicate at least when it comes to mic skillsthe final result isn't bad. It is kind of odd that Black Rob would make two separate appearances on an album by a group to which he is not affiliated, but this is the best I've heard from him in a while, so it's acceptable.

That said, this isn't bad, but it's nothing to write home about. Dear Abby, Miss Manners, and Billy Graham, maybe, but not your actual house, and not just because your house is an inanimate object and you would be wasting both your time and your stamps.

The underrated Sheek is the only member of The Lox that comes across as halfway decent. I know that Jadakiss and Styles P get all of the attention, but Sheek always sounds like he's trying at least four times as hard to keep up, which I appreciate. But it's not enough.

Which is absurd, by the way, when you actually hear the chorus: you will find yourself wondering what the hell Violator was thinking. A skit in incredibly poor taste. It would be one thing if it were actually funny Unless they were used to make water balloons, which would just make them a huge waste of resources.

Which you could also classify this song as. I don't like the guy's voice in small doses: imagine how I feel about spending three minutes with the guy. It probably doesn't even compare to any actual Donald Goines novel as I've never read any of the booksbut enjoyable nonetheless. The tactic may have actually gotten radio spins for Cru and gasp! I'm up! Sorry, dozed off for a bit, but that's to be expected with the overlong bloated affair that is Da Dirty LOUNGIN' WIT MY CRU Reminds me of one of those chilled-out club songs that they played on the radio in my area a lot back inlike Mad Skillz's "Move Ya Body", and sounds amost as good, but with one glaring defect: the most annoying part of the song the hook, which features The Mighty Ha repeating "I like" is the only part that will stand out in your mind, and that alone will make you hit the skip button.

We're almost home, kids. Questionable in a "who the fuck do these guys think they are" kind of way. Honestly, though, all of those concerns fly out the window when DJ Footlong appears to close out the album in the most dumbass way possible, thus negating the entire listening experience as a whole.

Yogi and Chadeeo come across as a less talented and more thugged-out A Tribe Called Quest oh, that's where the Q-Tip comparison comes in! Overall, the disc is a disappointment, regardless of what ego trip's Big Book of Rap Lists or a lot of other blogs would have you believe.

Full head helmet, covering the face and some degree of protection for limbs is mandatory in addition to very strong armor for the torso. An insert to protect the spine is usually applied to the back, in case an explosion throws the wearer. Visibility and mobility of the wearer is severely limited, as is the time that can be spent working on the device.

Armor designed primarily to counter explosives is often somewhat less effective against bullets than armor designed for that purpose.

The sheer mass of most bomb disposal armor usually provides some protection, and bullet-specific trauma plates are compatible with some bomb disposal suits. Bomb disposal technicians try to accomplish their task if possible using remote methods e. Actually laying hands on a bomb is only done in an extremely life-threatening situation, where the hazards to people and critical structures cannot be lessened by using wheeled robots or other techniques.

It is notable that despite the protection offered, much of it is in fragmentation. According to some sources, overpressure from ordinance beyond the charge of a typical hand grenade can overwhelm a bomb suit. In some media, an EOD suit is portrayed as a heavily armoured bulletproof suit capable of ignoring explosions and gunfire; In real life this is not the case, as much of a bomb suit is made up of only soft armor.

In the mids the state of California Department of Corrections issued a requirement for a body armor using a commercial ice pick as the test penetrator.

The test method attempted to simulate the capacity of a human attacker to deliver impact energy with their upper body. As was later shown by the work of the former British PSDB, this test overstated the capacity of human attackers.

The test used a drop mass or sabot that carried the ice pick. Using gravitational force, the height of the drop mass above the vest was proportional to the impact energy. The ice pick has a 4 mm 0. The California standard did not include knife or cutting-edge weapons in the test protocol. In this early phase only titanium and steel plate offerings were successful in addressing this requirement.

Point Blank developed the first ice pick certified offerings for CA Department of Corrections in shaped titanium sheet metal. Vests of this type are still in service in US corrections facilities as of The transition from hard, dense clay-based Roma to soft low-density gelatin allowed all textile solutions to meet this attack energy requirement.

Soon all textile "ice pick" vests began Bulletproof Vest - CRU - Da Dirty 30 (Cassette be adopted by California and other US states as a result of this migration in the test methods.

It is important for users to understand that the smooth, round tip of the ice pick does not cut fiber on impact and this permits the use of textile based vests for this application. The earliest of these "all" fabric vests designed to address this ice pick test was Warwick Mills's TurtleSkin ultra tightly woven para-aramid fabric with a patent filed in Their program adopted a rigorous scientific approach and collected data on human attack capacity.

Two commercial knives were selected for use in this PSDB test method. In order to test at a representative velocity, an air cannon method was developed to propel the knife and sabot at the vest target using compressed air. The introduction of knives which cut fiber and a hard-dense test backing required stab vest manufacturers to use metallic components in their vest designs to address this more rigorous standard. This standard, like the stab standards, is based on drop testing with a test knife in a mounting of controlled mass.

The slash test uses the Stanley Utility knife or box cutter blades. The slash standard tests the cut resistance of the armor panel parallel to the direction of blade travel. The test equipment measures the force at the instant the blade tip produces a sustained slash through the vest. The criteria require that slash failure of the armor be greater than 80 newtons of force. Vests that combined stab and ballistic protection were a significant innovation in the s period of vest development. However police forces were evaluating their "street threats" and requiring vests with both knife and ballistic protection.

This multi-threat approach is common in the United Kingdom and other European countries and is less popular in the USA. Unfortunately for multi-threat users, the metallic array and chainmail systems that were necessary to defeat the test blades offered little ballistic performance.

The multi-threat vests have areal densities close to the sum of the two solutions separately. These vests have mass values in the 7. These designs were used extensively by the London Metropolitan Police Service and other agencies in the United Kingdom. As vest manufacturers and the specifying authorities worked with these standards, the UK and US Standards teams began a collaboration on test methods. The use of commercial knives with inconsistent sharpness and tip shape created problems with test consistency.

As a result, two new "engineered blades" were designed that could be manufactured to have reproducible penetrating behavior. The tissue simulants, Roma clay and gelatin, were either unrepresentative of tissue or not practical for the test operators. A composite-foam and hard-rubber test backing was developed as an alternative to address these issues. The drop test method was selected as the baseline for the updated standard over the air cannon option. The drop mass was reduced from the "ice pick test" and a wrist-like soft linkage Album) engineered into the penetrator-sabot to create a more realistic test impact.

The lowest level of this requirement at 25 joules was addressed by a series of textile products of both wovens, coated wovens and laminated woven materials. All of these materials were based on Para-aramid fiber. The co-efficient of friction for ultra high molecular weight polyethylene UHMWPE prevented its use in this application.

These ceramic-coated products do not have the flexibility and softness of un-coated textile materials. For the higher levels of protection L2 and L3, the very aggressive penetration of the small, thin P1 blade has resulted in the continued use of metallic components in stab armor. In Germany, Mehler Vario Systems developed hybrid vests of woven para-aramid and chainmail, and their solution was selected by London's Metropolitan Police Service.

This system is currently implemented in the Netherlands. In many countries there is also an interest to combine military style explosive fragmentation protection with bullet-ballistics and stab requirements.

In order for ballistic protection to be wearable the ballistic panels and hard rifle-resistant plates are fitted inside a special Album). The carrier is the visible part of a ballistic vest. The most basic carrier includes pockets which hold the ballistic panels and straps for mounting the carrier on the user.

There are two major types of carriers: military or tactical carriers that are worn over the shirt, and covert law enforcement type carriers that are worn under the shirt. The military type of carrier, English police waistcoat carrier, or police tactical carrier most typically has a series of webbing, hook and loop, and snap type connectors on the front and back face. This permits the wearer to mount various gear to the carrier in many different configurations.

This load carriage feature is an important part of uniform and operational design for police weapons teams and the military. In addition to load carriage, this type of carrier may include pockets for neck protection, side plates, groin plates, and backside protection. Because this style of carrier is not close fitting, sizing in this system is straightforward for both men and women, making custom fabrication unnecessary. Law enforcement carriers in some countries are concealable.

The carrier holds the ballistic panels close to the wearer's body and a uniform shirt is worn over the carrier. This type of carrier must be designed to conform closely to the officer's body shape.

For concealable armor to conform to the body it must be correctly fitted to a particular individual. Many programs specify full custom measurement and manufacturing of armor panels and carriers to ensure good fit and comfortable armor. Officers who are either female or significantly overweight have more difficulty in getting accurately measured and having comfortable armor fabricated.

A third textile layer is often found between the carrier and the ballistic components. The ballistic panels are covered in a coated pouch or slip. This slip provides the encapsulation of the ballistic materials. Slips are manufactured in two types: heat sealed hermetic slips and simple sewn slips. For some ballistic fibers such as Kevlar the slip is a critical part of the system. The slip prevents moisture from the user's body from saturating the ballistic materials.

This protection from moisture cycling increases the useful life of the armor. The vast majority of hard body armor plates, including the U. Monolithic plates are lighter than their non-monolithic counterparts, but suffer from reduced effectiveness when shot multiple times in a close area i.

However, several non-monolithic armor systems have emerged, the most well-known being the controversial Dragon Skin system. Dragon Skin, composed of dozens of overlapping ceramic scales, promised superior multi-hit performance and flexibility compared to the then-current ESAPI plate; however, it failed to deliver. When the U. LIBA uses an innovative array of ceramic pellets embedded in a polyethylene backer; [71] [72] although this layout lacks the flexibility of Dragon Skin, it provides impressive multi-hit ability as well as the unique ability to repair the armor by replacing damaged pellets and epoxying them over.

Ballistic vests use layers of very strong fibers to "catch" and deform a bullet, mushrooming it into a dish shape, and spreading its force over a larger portion of the vest fiber. The vest absorbs the energy from the deforming bullet, bringing it to a stop before it can completely penetrate the textile matrix.

Some layers may be penetrated but as the bullet deforms, the energy is absorbed by a larger and larger fiber area. In recent years, advances in material science have opened the door to the idea of a literal "bulletproof vest" able to stop handgun and rifle bullets with a soft textile vest, without the assistance of additional metal or ceramic plating.

However, progress is moving at a slower rate compared to other technical disciplines. The most recent offering from Kevlar, Proterawas released in Current soft body armor can stop most handgun rounds which has been the case for roughly 15 years [ citation needed ]but armor plates are needed to stop rifle rounds and steel-core handgun rounds such as 7. The para-aramids have not progressed beyond the limit of 23 grams per denier in fiber tenacity.

Modest ballistic performance improvements have been made by new producers of this fiber type. Improvements in this material have been seen in the development of cross-plied non-woven laminate, e.

Spectra Shield. The major ballistic performance advance of fiber PBO is known as a "cautionary tale" in materials science. However this higher tenacity was delivered with a well-publicized weakness in environmental durability. Akzo-Magellan now DuPont teams have been working on fiber called M5 fiber ; however, its announced startup of its pilot plant has been delayed more than 2 years.
