Резюме
Bulletproof vests, pioneered by Richard Davis, utilize Kevlar, a synthetic fiber developed by Stephanie Kwolek. Kevlar's unique polymer structure allows it to absorb and dissipate energy from bullets, making it stronger than steel. Despite some limitations, Kevlar remains essential in various applications, including personal protection and industrial uses.
