Question

what is used for making bullet proof jackets

Answer 1

Answer:

Bullet proof jackets are made of many layers of woven or laminated fibres and can protect the wearer from small-calibre handgun and shotgun projectiles, and small fragments from explosives such as hand grenades.

Answer 2

Answer:

Kevlar has been the standard material since. In 1989, the Allied Signal Company developed a competitor for Kevlar and called it Spectra. Originally used for sail cloth, the polyethylene fiber is now used to make lighter, yet stronger, nonwoven material for use in bulletproof vests along-side the traditional Kevlar.
