<p>Thermoplastic toughened epoxy resin for use in making prepreg for aerospace applications. The resin includes an epoxy resin component comprising a tri functional epoxy resin and/or tetra functional epoxy, a thermoplastic component and 4,4′-Bis(p-aminophenoxy)biphenyl (BAPB) as the curing agent. The use of BAPB as a curative was found to increase the resistance of the cured resin to attack by solvents.</p> |
