Aramid Aromatic polyamide

Graphite is an excellent but expensive reinforcement for plastics. Aramid (aromatic polyamide), polyester (polyethylene terephthalate PET), and boron filaments are also used as reinforcements for polymers. [Pg.125]

Aramid Aromatic polyamide, made from a linear polymer containing recurring amide groups (—CO— NH—) joined directly to two aromatic rings. [Pg.1049]

Aramid Fibers. Aramid (aromatic polyamide) fibers such as Kevlar (DuPont) and Twaron (Akzo Nobel) are made of poly(paraphenylene terephthala-mide). The polymer can be prepared by solution polycondensation of p-phenylene diamine and terephthaloyl chloride at low temperatures. The fiber is spun by extrusion of a solution of the polymer in a suitable solvent (for example, sulphuric acid), followed by stretching and thermal annealing treatment. Tech-nora (Teijin) fibers are slightly different from Kevlar and Twaron as they consist of a copolymer poly(paraphenylene terephthalamide-co-3,4-oxydiphenylene terephthalamide). Various grades of Kevlar fibers are produced (Kevlar-29, 49, and 149), Kevlar-49 being the one more commonly used in composite structures. [Pg.7045]

Polymeric fibers. All types of ehemieal fibers known can be employed for polyolefin reinforeement thus aramid (aromatic polyamide) polyamides, polyesters polyvinyl alcohol fibres, cellulose fibers [2, 5, 52, 70-72, 77], etc. are used the polyolefin fibers (sueh as UHMWPE) themselves are applied as reinforcements in other composites. [Pg.608]
