Abstract: A curable resinous material, and a method of manufacturing same, the curable resinous material comprising a resinous matrix material (R) with thermoplastic material (TP) distributed therein, some of said thermoplastic material (TP) being substantially fully dissolved in the matrix resin material (R) with other of the thermoplastic materials (TP) being only partially dissolved within the matrix material (R) when the resinous material is cured. The invention also provides a curable resinous material, and a method of manufacturing same, comprising a resinous matrix material (R) and a thermoplastic material (TP) distributed within the resinous matrix material (R) so that at least some of said thermoplastic material (TP) remains partially undissolved in the resinous matrix material (R) when cured.

Abstract: A moulding material comprising a fibrous layer carrying resinous material to have at lest one area of relatively high resin content and at least one other area of relatively low resin content defined on a surface of the fibrous layer such that upon curing or partial curing resin from the said relatively high resin content area(s) moves over the relatively low resin content area(s) to provide a substantially even distribution of resin between the areas.
