Composite structure

Structure stratifiée composite

Abstract

A composite structure comprising: (a) at least one layer comprising at least one uncured or partly cured thermoset resin precursor; (b) in contact therewith, at least one layer comprising at least one amorphous thermoplast, said precursor and said amorphous thermoplast having mutual solubility at a temperature between ambient and thermoset cure temperature; and (c) reinforcing fibre present in either or both of said layers and/or between them. The relative thicknesses of layers (a) and (b) are preferably such that, on curing or further curing, layer (b) merges sufficiently into layer (a) to leave distinguishable thermoplast under 5% of total initial thickness. The thermoplast is preferably a polyarylether containing sulphone groups in its chain.
