One liquid type cyanate-epoxy composite resin composition

Abstract

The present invention is one liquid type cyanate-epoxy composite resin composition that is comprised of cyanate ester resin (A), epoxy resin (B) and latent curing agent (C) and has high thermal resistance as well as excellent fast curing properties and storage stability, characterized in that the above latent curing agent is comprised of a modified amine compound (a) and a phenol resin (b). Where, the modified-amine compound (a) is obtained by the reaction of at least one kind of amine compounds (a-1), selected from amine compounds having one or more tertiary amino groups and one or more primary and/or secondary amino groups, with an epoxy compound (a-2), in particular. It is preferable that one liquid type cyanate-epoxy composite resin composition of the present invention contains 1-10,000 mass parts of the epoxy resin component of the component (B) relative to 100 mass parts of cyanate-ester resin component of the component (A). The using amount of the latent curing agent of the component (C) is preferred to be 1-100 mass parts relative to 100 mass parts of the whole components (A) and (B).
