Abstract
An epoxy resin composition useful as a matrix for fiber-reinforced composites is disclosed which includes a mixture containing 30-95% by weight of a tetrafunctional epoxy resin, 3-40% by weight of an admixture of trifunctional epoxy resin oligomers and 2-50% by weight of a bisphenol A epoxy resin having a number average molecular weight of 450-1,300 and such a weight average molecular weight as to provide a ratio of the weight average molecular weight to the number average molecular weight of 1.3-3.0.
