Bullet-proof clothing

LCP fibres are used for making heavy-duty ropes and belts and also as the reinforcing fibres of composite materials. An important application of Kevlar is in the fabrication of bullet-proof clothing. The easy mouldability, good mould filling and low thermal expansion of thermotropic LCPs, combined with their resistance to solvents and their stability at temperatures up to 120 °C or higher make them suitable for precision mouldings for use in a variety of components such as electrical connectors. 

Beyond the usual mechanical and electrical performances, this review also points out the emergence of other original properties, like the remarkable capability of some nanotube/PVA composites to absorb mechanical energy and shape memory phenomena that differ from traditional behaviors of other polymers. These features are opening new investigation fields, in which several fundamental questions will have to be solved. But they also offer new opportunities for a variety of applications like smart or protective clothing, helmets, bullet proof vests, or active composites. 

The liquid crystalline polymer industry now covers diverse products, from high modulus rope to high strength composite, from the tennis racket to the radial tire cord, from the cover layer of the optical fiber to the microwave oven, from the bullet-proof vest to thermal insulated clothing, and from the electro-optic display to non-linear optical material, etc.

The exceptional properties of Kevlar have led to its use in making bullet-proof vests, ropes, fire-protective clothing (as used by Formula 1 racing drivers) and modern leathers worn by motorcycle riders. It is also used to reinforce other materials, such as the rubber in tyres.

Since important properties of the poly(p-aramide)s are quite different from those of Nomex , most apphcations are also different. Characteristic are applications as bullet-proof body armor, cut-fast gloves, substitute of asbestos, and as reinforcing component in concrete. They are also used as fibers in high performance tires for airplanes and racing cars, or as laminates for the constmction of boat hulls. Furthermore, poly(p-aramide)s are used for the production of sports articles, drum heads, brake pads, turbo hoses, optical fiber cables, or electrical-mechanical cables. Their fabrics serve as hot air filters and in combination with Nomex for the production of protective clothing and helmets. The total production of polyaramides amounts in 2008 to 60,000 tons. 

Forensic scientists work with physical evidence, ie, "data presented to a court or jury in proof of the facts in issue and which may include the testimony of witnesses, records, documents or objects." Physical evidence is teal or tangible and can HteraHy include almost anything, eg, the transient scent of perfume on the clothing of an assault victim the metaboHte of a dmg detected in the urine of an individual in a driving-under-the-influence-of-dmgs case the scene of an explosion or bullets removed from a murder victim s body.
