Hexcel® HexForce™ 345 Aramid Fabric
Categories: Other Engineering Material; Composite Fibers; Polymer; Thermoset; Aramid

Material Notes: Hexcel manufactures aramid fabrics for use in aerospace applications as well as marine, tooling and recreational products where high strength, low weight, and impact resistance are essential. Aramids display excellent dimensional stability with a slightly negative coefficient of thermal expansion (-2.4 X 10-6/ºC.) They are resistant to chemicals with the exception of a few strong acids and alkalis.
Aramids have excellent stability over a wide range of temperatures for prolonged periods. They show essentially no embrittlement or strength loss at temperatures as low as -320ºF (-196ºC). Aramids do not melt or support combustion but will start to carbonize at approximately 800ºF (427ºC).
