Ballistic vests

Kevlar fibers are supplied by DuPont as Kevlar-29 and 49. The former is characterized by high tensile strength and the latter by high initial modulus(4). Some Kevlar-29 end uses are in ropes and cables, which are as strong as steel at one-fifth the weight, and in ballistic vests. Some Kevlar-49 end uses are in reinforcing resins and composites for aerospace structures, boat hulls, and sport equipments. 

Aromatic heterocyclic rigid-rod polymers that have exceptional thermal oxidative stability have been prepared using 1,5-naphthylene dicarboxylic acid and 2,5-diamino-1, 4-benzenedithiol. These heterocyclic rigid-rod polymers materials are useful as protective garments in ballistic vests and abrasion- and flame-resistant fabrics. 

High modulus fibers as strong as steel but have one-fihh the weight, ideally suited as tire cord materials and for ballistic vests, e.g., Kevlar yXwaron. 

UHMWPE fibers are used in apphcations such as marine cordage and hfling slings, police and military ballistic vests, armored vehicles, cut-resistant gloves, fishing lines, and safety clothing.

The chemistry of these polymers was extended to terphthaloyl chloride and p-phenylenediamine, resulting in the commercialization of Kevlar fiber. Kevlar (structure shown below) is ideally suited for ballistic vests and high impact helmets because of its strength and the fact that it is as strong as steel but at one-fifth the... 

Abstract To ensure effective protection, protective clothing must be adapted to human morphology. The more a ballistic vest resembles the shape of the body, the more efficient the protection. This chapter describes the garment design process for a women s ballistic protection vest. It outlines the benefits of the darts rotation technique to ensure a good fit for comfort, obtain the required protective level and reduce the cost of the product. A 3D vest was designed, manufactured and tested, and found to be effective.

Ballistic protection can be obtained with fabric and with composite material. Both in ballistic vests and in helmets, a very high protection at a relatively low weight can be achieved. 

A combined stmcture has also been created to improve protection against balhstic impact. Steeghs et al. (2006) invented a type of ballistic vest containing a stack of...
