Novelties and Prospects of Conventional Fibres and High-Performance Fibres for Technical Application

Abstract

New possibilities of using natural cellulose fibres in biocomposites and of wool for technical applications, novelties in the development of man-made fibres from regenerated polymers for absorptive fiber materials, medical and hygienic applications, novelties in the development of conventional synthetic fibres (PES, PA, PP) for technical purposes, which are mainly based on new copolymers and on the use of new catalysts for polymer sythesis are explained. Due to simpler recycling, the development of polypropylene “all-PP” composites is interesting. Among new high-performance fibres, the fibres M-5 from polypiridobisimidazol should be exposed. Their extreme high-performance is ascribed to their chemical and mechanical properties. With their plastic behaviour when overloaded, these fibres surpass even inorganic carbon fibres.
