Aramid
Heat-resistant and strong aromatic polyamide
Aramid, or aromatic polyamide fibers are a class of strong, heat-resistant, synthetic fibers, commonly used in aerospace and military applications - e.g., ballistic-rated body armor fabric and ballistic composites, marine cordage and hull reinforcement - as a substitute for asbestos, and in lightweight consumer items, such as phone cases and tennis rackets. Individual amide molecules forming the aramid chain polymerise in the direction of the fiber axis, lending greater structural integrity to the resulting fiber.

From Wikipedia
Aramid, or aromatic polyamide fibers are a class of strong, heat-resistant, synthetic fibers, commonly used in aerospace and military applications - e.g., ballistic-rated body armor fabric and ballistic composites, marine cordage and hull reinforcement - as a substitute for asbestos, and in lightweight consumer items, such as phone cases and tennis rackets. Individual amide molecules forming the aramid chain polymerise in the direction of the fiber axis, lending greater structural integrity to the resulting fiber. This is due to the higher proportion of chemical bonds which contribute to the physical strength and thermal resistance (melting point >500 °C (932 °F)) versus other synthetic fibres, such as nylon. Notable brands of aramid fiber include Kevlar, Nomex, and Twaron.
