Composite material is used to reinforce fibre-reinforced plastic parts and comprises two outer fibre layers, and a middle layer made of elastic nonwoven

摘要

The fibres of the middle layer are tubular in shape and aligned vertically to the nonwoven surface. The reinforcing fibres of the outer layers are mineral fibres; the middle layer is made of polyester fibres and/or polyolefin fibres and contains additionally high-strength fibres with a reinforcing effect: glass, carbon, Aramid or basalt fibres.
