Kevlar is a strong, synthetic fiber known for its high tensile strength and durability. It was invented in 1965 by chemist Stephanie Kwolek and is primarily used in products that require resistance to impact and abrasion, such as bulletproof vests and helmets. This material is lightweight and flexible, making it ideal for protective gear. Kevlar is also used in various applications, including tires, ropes, and sporting equipment, due to its ability to withstand extreme conditions and provide safety without adding significant weight.
