Abstract

Composite structural members moulded or pultruded from plastics or ceramic material and containing fibre reinforcement configured such that in flange portions of the member reinforcing fibres lie predominantly at angles of 0 DEG to 90 DEG to an axis of the member whereas in web portions the reinforcing members lie predominantly in directions oppositely inclined to the axis, each at an angle in the range 30 DEG to 80 DEG . Reinforcing fibres are made up by, for example, knitting, braiding or weaving, into a preform having the desired fibre configuration, the preform being laid in a mould, pulled through a die or otherwise introduced during manufacture in any convenient manner. Highly accurate fibre placement is possible yielding greatly improved strength as compared with conventional techniques, at joints between web and flange portions of the member.
