Kevlar fiber has a wide range of uses from military to civilian use and is non-toxic.

Kevlar is a registered trademark of DuPont used on aramid organic fibers. This fiber is used as reinforcing fiber after glass fiber, carbon fiber and boron fiber, and was first industrialized by DuPont.

The tensile strength of this fiber is 4 times that of ordinary organic fibers, and its modulus is 9 times that of polyester. Due to the small specific gravity of Kevlar brand fiber, its specific strength is higher than that of glass fiber, carbon fiber and boron fiber. However, the compressive strength and shear strength are low, and the water absorption is high, which limits its application in some aspects. Kevlar brand fiber is mainly used to make ropes, cables, painted fabrics, bulletproof vests, and is used instead of glass fiber to make large solid rocket motor combustion chamber casings. It is also widely used as tire cord, which can withstand 150°C to 160°C. ℃ high temperature. Kevlar brand

Another important application of fiber is to replace carcinogenic asbestos and be used as reinforcing materials for brake pads, seals and clutch linings of various brakes.

Kevlar is DuPont's trademark used on its aromatic polyamide fiber ("aramid") products. This fiber was invented by DuPont in the 1960s. Kevlar ( Kevlar) is a registered trademark of DuPont. Pure Kevlar brand fiber is woven from high-ignition-point, temperature-resistant materials. The twisting and plying are definitely not the craftsmanship of the country of origin! The appearance color is bright light beige, smooth, and woven with filaments. The specifications are based on Divided in units of D, the pulling force increases as the number of strands increases![1]
