Method for manufacturing a flat, extended composite material with fibres and plastic impregnation

摘要

Two or more groups of parallel fiber strands(2,3) in bundle or strip form run in different directions to form a woven fabric, wicker construction or grid. Fibers of the first group(2) are more heavily impregnated with plastic(21) than fibers in the second group(3) so that the composite material(1) is stiff in the direction of the first fiber group and more flexible in the transverse direction. The reinforcement has open areas between the fiber groups. Independent claims are made for: a) a process for production of the composite material in which non-impregnated fiber strands are woven to form warp(2) and weft(3) fibers of a textile and then drawn through an impregnation bath in the warp direction; b) a use of the composite material in which the composite material is welded or bonded onto edges or cylindrical surfaces of machine or structural components.
