what are kevlar made of?
311934
Kevlar is synthesized in solution from the monomers 1,4-phenylene-diamine (para-phenylenediamine) and terephthaloyl chloride in a condensation reaction yielding hydrochloric acid as a byproduct. The result has liquid-crystalline behavior, and mechanical drawing orients the polymer chains in the fiber's direction.

Performance. Kevlar brake pads are created from organic materials making a softer brake pad which is better suited for small cars with fewer hard stops. For heavier vehicles or aggressive driving, ceramic pads dispense heat far better providing a quicker recovery after stopping.

First you have to produce the basic plastic from which Kevlar is made (a chemical called poly-para-phenylene terephthalamide—no wonder they call it Kevlar). Second, you have to turn it into strong fibers.

Typically the sleeves are made of a foil-like material with some combination of copper and aluminum, and then covered in a strong material like Tyvek. RFID wallets and purses usually have the blocking foil-like material sewn into them and function just like the sleeve.

What is Soft Body Armor? As the name suggests, soft body armor is soft and flexible, though its components can be many times stronger than steel. ... Soft armor is usually made of a fabric-like material with extreme strength such as Kevlar, Spectra, Twaron, and so on.

Most modern ships are still built from steel today, although it's relatively heavy. That's why some larger boats are now made from strong, lightweight metals such as aluminum, while smaller ones are often made from light composites such as fiberglass or super-strong plastics like Kevlar®.

Kevlar® is used in both bulletproof and stab proof vests. ... The sharp edge of the knife is then unable to penetrate through to the flesh because it is caught within the Kevlar® weaving. Although the cutting motion will damage the vest carrier, the wearer will be protected from the knife.

Polyethylene (UHMWPE) Plates Polyethylene armor is made by bonding unidirectional Ultra High Molecular Weight Polyethylene Fibers over the High Density Polyethylene sheet. Such sheets are place in mold, cut to shape, and compressed under high pressure and heat, which results to a cohesive hard armor plate.

What are they made of ? Evoshield pads are made from a balistic pad called backface deformation. The pad is used in millitary helmets such as the A7 and some protection vests. The material isn't fully bullet proof but it save really does help.
