Abstract
A solvent-free epoxy resin matrix composition comprising: (a) a liquid epoxy resin or a liquid mixture of epoxy resins, (b) a benzylidenamine compound, (c) an aliphatic or cycloaliphatic primary monoamine and/or disecondary diamine; and (d) a catalytically curing tertiary amine. The epoxy resin matrix composition is used as an impregnating resin to form impregnated fiber composite materials.
Claims8
A fibre composite impregnated with a curable, solvent-free epoxy resin matrix composition, said composition comprising:
- (a) a liquid epoxy resin or a liquid mixture of epoxy resins,
- (b) a benzylidenamine compound obtained by reacting a benzaldehyde of the formula (I)
- in which R1 is hydrogen, C1-C5 alkyl or C1-C5 alkoxy, with a primary amine,
- (c) an aliphatic or cycloaliphatic primary monoamine and/or disecondary diamine, and
- (d) a catalytically curing tertiary amine,
- the curable epoxy resin matrix composition containing from 0.15 to 0.8 amine hydrogen equivalent of the amine component (c) and from 0.01 to 0.1 mol of the tertiary amine (d) per epoxide equivalent of the epoxy resin (a).
