Aramid in Ballistic Protection
topic
Body armor applications (40% of para-aramid use): soft armor vests (multiple layers of woven or UD fabric, 20-40 plies, 2-5 kg for NIJ IIIA protection against handguns), hard armor plates (aramid-ceramic composites for rifle protection), helmets (Kevlar/epoxy composites, 1.2-1.5 kg providing IIIA protection), and vehicle armor (B6/B7 level protection). Energy absorption: 30-80 J/g·m² depending on fabric architecture and backing.
Role
Aramid's combination of high specific tensile strength, energy absorption through fibre elongation and inter-yarn friction, and fabric flexibility enables concealable body armor, protecting military and law enforcement (estimated 3,000+ lives saved by Kevlar vests).
