Tensile strength. The chemical structure of Kevlar® is comprised of several repeating inter-chain bonds. These chains are cross-linked with hydrogen bonds, providing a tensile strength can be up to 10X stronger than steel* on an equal weight basis.

When Kevlar is spun, the resulting fiber has a tensile strength of about 3,620 MPa (525,000 psi), [23] and a relative density of 1.44 (0.052 lb/in 3). The polymer owes its high strength to the many inter-chain bonds.

2019年3月11日 · 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.

Kevlar has a measured tensile strength of about 3,620 megapascals, whereas nylon has a tensile strength of about 75 megapascals (depending on the types of nylon and Kevlar). Kevlar doesn’t lose much strength in extreme colds, nor does it lose strength unless it …

2023年5月17日 · The specific tensile strength (stretching or pulling strength) of both Kevlar 29 and Kevlar 49 is over eight times greater than that of steel wire. [6] Unlike most plastics it does not melt: it's reasonably good at withstanding temperatures and decomposes only at …

Kevlar ® aramid fiber is a high strength, intermediate modulus, organic fiber. Its high tenacity and low thermal shrinkage make it similar to S glass. It is inherently flame-resistant and self-extinguishing, charring at 800ºF (425ºC).

2006年10月17日 · Only with bright synchrotron radiation could the secret strength of KEVLAR be revealed. As you have discovered, there are many components that contribute to the strength of KEVLAR, including the fact that KEVLAR is a polymer …

It is available in three different types: KEVLAR ® 49, with its high tensile strength (400,000 psi; 2760 MN/m 2) and high modulus (18 million psi; 124,000 MN/m 2) is designed for the reinforcement of plastics and offers industry a new level of composite performance.

DuPont™ Kevlar® fibers are used in a variety of clothing, accessories, and equipment to help make them safer and more durable. With five times the strength of steel based on an equal weight basis, it’s the go-to fiber for protective apparel and accessories.
