Kevlar was the principal fibre into the 1970s. There are several new ones, including Dyneema, Gold Flex and Spectra. For more information please see the wikipedia article about bullet proof vests.
Kevlar is commonly used in bulletproof jackets and vests due to its high strength and ability to absorb and disperse impact energy, making it effective in stopping projectiles.
