IMPROVEMENTS IN OR RELATING TO FIBRE REINFORCED COMPOSITES

摘要

A laminated structure comprising a plurality of layers of fibre reinforced thermoset resin in which the layers are selected from two or more of the following i) a first moulding material comprising a layer of curable resin and a fibrous material on at least one side of the curable resin matrix, said moulding material further comprising a further fibrous layer adhered to the fibrous reinforcement material; ii) a second moulding material comprising a fibrous material comprising two cross bonded fibrous plies, each ply comprising fibre tows oriented at differing angles, the fibrous material further comprising a curable resin matrix; iii) a third moulding material comprising at least two reinforcement layers having unidirectional fibre tows and a curable resin matrix bonding the layers together; iv) a fourth moulding material comprising a layer of fibrous reinforcement and a curable liquid resin wherein the fibrous reinforcement comprises a plurality of tows each tow comprising a plurality of filaments wherein resin is provided at least partially between interstices between tows of the fibrous reinforcement to provide an air venting path in at least the interior of the tows; and v) a resin impregnated fibrous layer.
