Abstract
Abstract Specification describes material for use in forming fibre reinforced structures comprising longitudinally extending fibre reinforcing material having a thermoplastics resin intimately associated therewith along the length thereof. The thermo-plastics resin may be formed as a coating along the length of the fibre and/or as part of a composite fibre. The coating may be applied to the fibre by passing the fibre through an extrusion press or bath of molten thermo-plastics material. The material so formed may be used to form fabric by weaving, knitting orthe like or may be used directly subsequent-to being chopped into short lengths. Various structures for use in the aircraft industry, and the methods of making those structures from the material are described.
