Density of aramid
WebAbstract. Aramid fibres are very tough and strong polymer materials. The modulus of elasticity of these fibres can range from 60 to 140 GPa, whereas the strength reaches a … 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 reinforcement, as an asbestos substitute, and in various … See more Aramid is a shortened form of aromatic polyamide. The term was introduced in 1972, accepted in 1974 by the Federal Trade Commission of the USA as the name of a generic category of fiber distinct from See more World capacity of para-aramid production was estimated at about 41,000 tonnes per year in 2002 and increases each year by 5–10%. In 2007 this means a total production capacity of around 55,000 tonnes per year. Polymer preparation See more Aramids share a high degree of orientation with other fibers such as ultra-high-molecular-weight polyethylene, a characteristic that dominates their properties. See more Aromatic polyamides were first introduced in commercial applications in the early 1960s, with a meta-aramid fiber produced by DuPont as HT-1 and then under the trade name See more During the 1990s, an in vitro test of aramid fibers showed they exhibited "many of the same effects on epithelial cells as did asbestos, including increased radiolabeled nucleotide incorporation … See more Besides meta-aramids like Nomex, other variations belong to the aramid fiber range. These are mainly of the copolyamide type, … See more • flame-resistant clothing • heat-protective clothing and helmets • body armor, competing with polyethylene-based fiber products such as Dyneema and Spectra • composite materials See more
