When was Kevlar invented?
Kevlar is a heat-resistant and strong synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.

Which is stronger Kevlar or aramid?
1- Aramid fibers have High Strength to Weight Ratio Kevlar ® is very strong and is slightly stronger than Carbon Fiber per unit weight. Aramid fibres have remarkable strength to weight ratio when compared to other commercial fibres. Aramid fibre exhibits similar tensile strength to glass fibre, but can be twice as stiff.
Can Kevlar stop a knife?
Kevlar ® is used in both bulletproof and stab proof vests. The sharp edge of the knife is then unable to penetrate through to the flesh because it is caught within the Kevlar ® weaving. Although the cutting motion will damage the vest carrier, the wearer will be protected from the knife.
Is Kevlar better than steel?
Kevlar is an organic fiber in the aromatic polyamide (aramid) family that combines high strength with light weight, and comfort with protection. Kevlar is five times stronger than steel on an equal weight basis and provides reliable performance and solid strength.
