Kevlar is a strong synthetic fiber known for its high tensile strength and durability. It was developed in the 1960s by chemist Stephanie Kwolek at DuPont. Kevlar is most commonly recognized for its use in bulletproof vests, providing essential protection for law enforcement and military personnel. In addition to its use in personal protective equipment, Kevlar is also utilized in various applications such as tires, ropes, and sporting goods. Its lightweight nature and resistance to heat and abrasion make it an ideal material for products that require strength without adding significant weight.
