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 …

Created by Stephanie Kwolek, DuPont™ Kevlar® is a heat-resistant para-aramid synthetic fiber with a molecular structure of many inter-chain bonds that make Kevlar® incredibly strong. Best known for its use in ballistic body armor, Kevlar® also has many other applications because of its high tensile strength-to-weight ratio.

Kevlar® is an organic fiber in the aromatic polyamide family. The unique properties and distinct chemical composition of wholly aromatic polyamides (aramids) distinguish them—and especially Kevlar®—from other commercial, man-made fibers. Kevlar® has a unique combination of high strength, high modulus, toughness and thermal stability.

Apr 1, 2025 · Kevlar, trademarked name of poly-para-phenylene terephthalamide, a nylonlike polymer first produced by Du Pont in 1971. Kevlar can be made into strong, tough, stiff, high-melting fibres, five times stronger per weight than steel; it is used in radial tires, heat- or flame-resistant fabrics,

May 17, 2023 · Polymer means that Kevlar is made from many identical molecules bonded together (each one of which is called a monomer). Plastics are the most familiar polymers in our world. As we've seen, the monomers in Kevlar are based on a …

At its core Kevlar is an extremely lightweight, yet strong synthetic polymer that is weaved into a material that is 5 times stronger than steel when the weight is equal. Kevlar has an incredibly high tensile strength that is 8 times stronger than steel wire.

Polymer composites can use Kevlar as a reinforcement instead of glass or carbon fiber. The aromatic nylon fiber, Kevlar, can be combined with polyamides (nylon), polyesters, epoxies, polypropylene, or PEEK. The plastics can be combined with the Kevlar and then compression molded into a plastic part.

The unique properties and distinct chemical composition of wholly aromatic polyamides (aramids) distinguish them - and especially Kevlar® - from other commercial, man-made fibers. Kevlar® has a unique combination of high strength, high modulus, toughness and thermal stability.

Oct 17, 2006 · KEVLAR is a long, chain-like molecule known as a polymer, which consists of repeating units called monomers. A KEVLAR fiber is an array of molecules oriented parallel to each other like a package of uncooked spaghetti.

The chemical structure of Kevlar consists of long, rod-like polymer chains that are highly oriented and hydrogen-bonded, creating a rigid and tightly packed fiber. This molecular arrangement gives Kevlar its extraordinary strength and heat resistance.
