blunt trauma on body armour: the bullet energy can kill you

most people believe that the job of the body armour is to stop the bullet…..extremely wrong….you can die because of the blunt trauma, the energy of the bullet is a killer most of the time….even if the bullet is stopped…

the job of a good bulletproof vest is to stop the bullet and disperse the energy of the impact the fastest way possible on the fastest surface possible, to avoid a destructive impact on key organs

this video shows a simple way how is it possible and what the theory is about: sels explanatory

Aramid sewing yarns

Aramid sewing yarns or threads are commonly used for stitching aramid fabric layers together.

It gives a stronger stitching. Main applications are body armour to stitch to reinforce unions between different layers and make a strong panel.

Body Armor for women: the never ending story

Pentagon has once more the debate on the table and the challenge to improve body armor for women.

So many years talking about the same issue. Many designs, tricks with fabrics, UD and vest designs have been developped.

Seriously, nothing really works or what is the problem of what exists…i am not sure to understand what’s going on here.

Comments are welcome.

Advancements in body armour can come quickly enough for sweltering officers – Posted Toronto

By Michael McKiernan, National Post

When Constable Hugh Smith was a member of the Toronto Police Service bike patrol, he was embarrassed constantly. Those were the days officers wore light blue shirts — all the better to show sweat stains. The problem wasn’t his constant cycling — it was his body armour.

“The material is not breathable at all, so you find yourself almost constantly rehydrating. By the end of the day, it’s soaked with sweat,” said Const. Smith, now an officer with Toronto Police Service’s public information unit.

His Canadian Body Armour Ltd. brand vest is produced by Pacific Safety Products, which supplies body armour to about 70% of police and security forces in Canada. The vests contain panels made from layers of tightly spun Kevlar. The synthetic fibre was developed in a DuPont laboratory for its high strength and extreme heat resistance, making it perfect for use in racing tires and NASA launch vehicles. But when wrapped around a police officer’s torso, the insulation locks in body heat, making for some uncomfortable hot summer days.

On the plus side, the 5mm-thick panels provide bullet protection comparable with steel, while weighing five times less.

That’s still too much weight to carry for Const. Shona Patterson, who spent a recent day searching for shade outside the University Avenue courthouse.

“It’s so heavy, which makes things worse,” she said. “And it hasn’t even been that hot this year. When it hits 30 degrees, it feels like you’re melting out here.”

Const. Smith says he appreciates his indoor posting at Toronto Police’s air-conditioned downtown headquarters on College Street. The force’s light blue shirts have been dropped in favour of a darker, stain-hiding navy blue version, but replacing the body armour is not an option, according to George Tucker, director of uniform field services with the Toronto Police Association.

“They save lives and they offer reassurance,” he said. “I think every officer realizes how critical they are as part of the uniform.”

Mr. Tucker joined the police in 1980, four years before body armour was introduced in Toronto on a voluntary basis. By the early 1990s, it had become mandatory. He says that vest technology has progressed since then and continues to improve.

“They were a lot more cumbersome then and the protection was minimal unless you wore the full outfit, which was two panels in the front and two in the back. Now we’re down to single panels,” he said. “The industry is driven by making the equipment lighter and easier to wear. It’s a constant battle between safety and comfort.”

According to Mr. Tucker, a safety scandal in the United States has set back the cause of comfortable body armour in recent years. In the late 1990s, police forces in several states adopted vests made from Zylon, a new lightweight synthetic material. Then in 2003, a police officer in Forest Hills, Pa., suffered serious injuries when his Zylon vest failed. The incident prompted an investigation by the National Institute of Justice and a rewrite for body armour regulations.

Vests in Toronto easily meet the minimum standard, which demands that a vest withstand a bullet fired from the officer’s own firearm, and Const. Smith understands the tendency to err on the side of safety.

“A lighter vest is not always going to mean a stronger one, and you don’t want to be taking any risks with the ballistics,” he said.

Advancement can’t come quickly enough though for Const. Patterson, who is counting down the days until the end of the summer.

“In winter, when it gets down to minus 20, at least you can layer up,” she said.

The Point Blank Drama Continues

Point Blank Solutions Inc. (OTCBB: PBSO) announced another delay in their annual meeting today, which has some shareholders furious and others grateful. The body armor manufacturer said they need to wait for the Army\’s IOTV contract award before completing their review of strategic alternatives, which includes a potential sale of the company to some 90 potential parties.

Point Blank has already been awarded with a bridge buy of 150,000 IOTV\’s for a total of $86.2 million while the Army finishes determining who will win the larger 736,000 IOTV contract. The latter could be worth around $200 million or more, which is more than Point Blank\’s current market capitalization. Obviously, the award would substantially impact PBSO\’s valuation to a potential buyer.

However, at least one activist investor is sick of constantly waiting around. Steel Partners, who has been involved with the company since its fraud charges, has been waiting for an annual meeting for over two years and is currently suing the company to hold it. Interestingly, the activist hedge fund is also holding a proxy contest to overtake the board.

“The postponement was a unilateral stunt pulled by a Board in fear of losing an election contest and was designed to block the democratic process, limit accountability and further entrench the Board and management team,\” said Steel Partners in a regulatory filing. \”Ask yourself whether you believe this Board was truly serious about exploring alternatives to maximize stockholder value or whether the Board was more interested in disenfranchising stockholders? We think the answer is obvious.\”

Supporters of Steel Partners believe that the hedge fund is simply trying to deliver shareholder value as quickly as possible. However, skeptics believe that they may be positioning themselves to acquire the company on the cheap before any major contract is awarded. After all, it is not uncommon for hedge funds to privatize a company during a turnaround when they are vulnerable and then re-IPO it later on and make bank.

Point Blank also faces problems with its former CEO David Brooks, who is facing criminal charges for fraud. Combined, Point Blank contends that it is facing adverse interests from both of these large shareholders and they say they are simply trying to protect the interest of the thousands of minority shareholders.

Defense Review – DuPont Kevlar XP: Next-Gen, Lightweight Aramid Ballistic Fiber for Body Armor

DuPont Kevlar XP: Next-Gen, Lightweight Aramid Ballistic Fiber for Body Armor

Body Armor By David Crane

15% less backface deformation signature (BDS), and thus reduced impact trauma a.k.a. blunt force trauma, with 10% reduction in overall (OA) weight, all in a 100% Kevlar, i.e. woven, high-strength ballistic aramid fiber, solution–this is the promise of DuPont Kevlar® XP™ woven ballistic aramid fiber for military and law enforcement (LE)/police body armor and other ballistic armor products (i.e. vehicle armor, aircraft armor, etc.) in the near future. Mark McGonagle, Global Marketing Manager for DuPont Personal Protection, describes Kevlar XP as a \”patented, next-generation woven fiber technology that enables more comfortable, more flexible, lighter-weight ballistic vests made with Kevlar fiber.\”

From what DefenseReview understands at present, the key to the improved performance of Kevlar XP is

a combination of new weaving and coating processes that are applied to an existing Kevlar product (unconfirmed/unverified). If this is the case, we\’re curious as to which existing Kevlar product is utilized. Perhaps Kevlar KM2 or Kevlar 129? We\’ll try to find out. We\’ll also try to glean more about the coating material(s) and process(es).

Kevlar XP can apparently consitently stop a .44 Magnum bullet in the first 2-3 layers of an 11-layer ballistic panel/vest. \”The bottom line is that it stops bullets faster,\” said Dale Outhous (yes, that\’s his real name), global business director for DuPont Personal Protection. Defense Review will try to find out if a Kevlar XP ballistic panel can stop any/all NIJ Level IIIA ballistic threats (high-velocity 9mm Parabellum and .44 Magnum rounds) within this 2-3-layer envelope. One of the people we\’re going to try to reach about this is our friend and professional contact Mike Foreman at Point Blank Solutions, Inc. (PBS), who\’s apparently already familiar with the product. According to him, PBS already has two prototype body armor systems that utilize Kevlar XP. Point Blank Solutions is the parent company of Point Blank Body Armor, Inc.

According to Outhous, ballistic vests utilizing Kevlar XP should be available \”later this summer\”, and will cost roughly the same amount as current Kevlar-based vests ($400-$1,000). Kevlar XP may help strengthen Kevlar\’s position against competing high-end ballistic fibers, including aramid fibers like Twaron, which is madee by Teijin Aramid/Teijin Techno Products Limited (Japan), and polyethylene fibers like Dyneema, which is made by DSM Dyneema (Geleen, the Netherlands).

Since DuPont is a juggernaut company, and Kevlar is a well-established and proven product over many years, DefenseReview predicts that an improved Kevlar product like Kevlar XP will do very well in the marketplace, provided it lives up to the initial hype. Time will tell.
