Twaron is the brandname of Teijin Aramid for a para-aramid. It is a heat-resistant and strong synthetic fibre developed in the early 1970s by the Dutch company AKZO, division ENKA, later Akzo Industrial Fibres. The research name of the para-aramid fibre was originally Fiber X, but it was soon called Arenka. Although the Dutch para-aramid Full Article…
Technora is an aramid that is useful for a variety of applications that require high strength or chemical resistance. It is a brand name of the company Teijin. It was also used to suspend the NASA Mars rover Opportunity from its parachute during descent. Production Technora is produced by condensation polymerisation of terephthaloyl chloride (TCl) Full Article…
Aramid fibres are a class of heat-resistant and strong synthetic fibres. They are used in aerospace and military applications, for ballistic rated body armour fabric and ballistic composites, in bicycle tires, and as an asbestos substitute. The name is a portmanteau of “aromatic polyamide”. They are fibres in which the chain molecules are highly oriented Full Article…
Kevlar is the registered trademark for a para-aramid synthetic fibre, related to other aramids such as Nomex and Technora. Developed at DuPont in 1965, this high strength material was first commercially used in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can Full Article…
Pre-preg is a term for “pre-impregnated” composite fibres. These usually take the form of a weave or are uni-directional. They already contain an amount of the matrix material used to bond them together and to other components during manufacture. The pre-preg are mostly stored in cooled areas since activation is most commonly done by heat. Full Article…
Carbon fibre or carbon fibre in Europe, alternatively graphite fibre, carbon graphite or CF, is a material consisting of fibres about 5–10 μm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fibre. The crystal Full Article…
