Fibre reinforced epoxy! resin composites - made from curable mixt. of epoxy! prepolymer and a poly:amino benzoate curing agent

摘要

A fibre/resin matrix comprises (a) non-siliceous reinforcing filaments and (b) a heat curable epoxy resin compsn. comprising (i) one or more epoxy prepolymers having more than one epoxide gp./mol and (ii) an effective amt. of one or more amine-functional curing agents of formula (I), in which a = 2 or 3, R = H, alkyl or aryl and X = divalent or trivalent organic hydrocarbon, hetero-interrupted hydrocarbon, substd. hydrocarbon radical or -N-.
