Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, [ 3 ] [ 2 ] [ 4 ] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Aramid. Spools of aramid yarn destined for body armor. Fiberglass-aramid hybrid cloth. Aramid fibers, short for aromatic polyamide, are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull ...
Fire blanket. A fire blanket is a safety device designed to extinguish incipient (starting) fires. It consists of a sheet of a fire retardant material that is placed over a fire in order to smother it. Small fire blankets, such as for use in kitchens and around the home are usually made of glass fiber and sometimes kevlar, and are folded into a ...
Combustibility and flammability. A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
Nomex is produced by condensation reaction from the monomers m -phenylenediamine and isophthaloyl chloride. [1] It is sold in both fiber and sheet forms and is used as a fabric where resistance from heat and flame is required. Nomex sheet is actually a calendered paper and made in a similar fashion. Nomex Type 410 paper was the first Nomex ...
Flame retardant. Open-flame tests compare the flammability of untreated polyurethane foam (top) and an identical foam sample surface treated with a sandwich-like coating incorporating layered double hydroxides. By 90 seconds after ignition the untreated foam is completely consumed. Flame retardants are a diverse group of chemicals that are ...
Liquid Armor. Liquid armour is a material under research by defense institutions and universities around the world including the United States Army Research Laboratory (ARL). [1][2][3] Some of the earliest research in this area was performed at Massachusetts Institute of Technology [4] and University of Delaware [5] in 2003.
A carbon-fiber and Kevlar canoe (Placid Boatworks Rapidfire at the Adirondack Canoe Classic) CFRPs are now widely used in sports equipment such as in squash, tennis, and badminton racquets, sport kite spars, high-quality arrow shafts, hockey sticks, fishing rods, surfboards, high end swim fins, and rowing shells.
