Thermosettable fiber reinforced resin compositions

Claim 1

A curable molding composition consisting of a mixture of: I. from about 25 to 50 weight percent of a thermosetting resin containing: (a) from about 25 to about 75 weight percent of a polyesfter resin produced by the coreaction of a poly(acrylate) and styrene in the presence of a catalyst for said coreaction, said poly(acrylate) being essentially free from functional groups reactive with the polyol or the polyisocyanate of (b); said poly(acrylate) being characterized by the following emprical formula: ##STR12## wherein R is the residue of an organic polyhydric alcohol which contained alcoholic hydroxyl groups bonded to different carbon atoms, R 1 and R 2 are independently hydrogen or methyl, and n is 1 to 3; (b) from about 75 to about 25 weight percent of a polyurethane produced by the reaction of (i) a saturated polyol having a functionality of from about 2 to about 8 and an equivalent weight of from about 30 to about 350 and (ii) a polyisocyanate having an isocyanate equivalent weight of less than about 300, said polyol and polyisocyante being free from unsaturated groups capable of copolymerizing with the poly(acrylate) or styrene of (a); and II. from about 75 to about 50 weight percent of one or more fibers having a melting point or a glass transition temperature above about 130° C.; wherein (b) constitutes less than 40 weight percent of (I) and (II).
