	A manufactured fiber in which the fiber-forming substance is any long chain synthetic polyamide in which at least 85% of the amide linkages are directly attached to two aromatic rings (Federal Trade Commission definition). Two types of aramids, meta-aramid (e.g., [[Nomex\|Nomex®]]) and para-aramid (e.g., [[Kevlar\|Kevlar®]]) are made. Both types of aramid fibers are lightweight and provide extremely high strength. They also have excellent temperature, abrasion and stretch resistance. In addition, meta-aramids are soft and electrically conductive. Para-aramids are stiff, and have greater tenacity and strength than the meta-aramids. However, para-aramids are sensitive to chemicals and will degrade in the presence of acids, alkalis and bleaches. In general, aramids are used in many applications such as bulletproof vests, aerospace construction, protective clothing, high pressure hoses, tires, ropes and high strength honeycomb foams ("HRH 10").
