摘要

A fibrous composite structure impregnated with a solvent-free, curable epoxy resin matrix and comprisingPP(a) a liquid epoxy resin or a liquid mixture of epoxy resins,PP(b) a liquid . beta.-hydroxyamine of formula I ##STR1## wherein X is phenyl or the radical R--O--CH.sub.2 --, wherein R is an alkyl group of 4 to 20 carbons or is phenyl or phenyl which is substituted by one or more C.sub. 1 -C.sub. 4 alkyl groups, a liquid mixture of &bgr;-hydroxyamines of formula I or a liquid mixture of one more &bgr;-hydroxyamines of formula I and of a primary monomaine different from formula I or of a primary or secondary diamine, and optionallyPP(c) a catalytically curing tertiary amine,PPis virtually odourless, can be stored for several days at room temperature, and has good processing properties.
