OPTIMUM FORMULATION REGIONS OF REINFORCED THERMOSET COMPOSITES

摘要

This invention relates to optimum formulation regions of reinforced thermosetting resin composites incorporating substantially increased filler loadings which have been found to retain the impact strength of formulation regions with substantially less filler loadings. The reinforced thermosetting resin composite of this invention comprises (a) 15 to 23 weight percent resin matrix selected from the group consisting of polyester and epoxy, (b) 5 to 25 equivalent weight percent fiber reinforcement, said fiber reinforcement comprising 0 to 80 volume percent glass fiber and 100 to 20 volume percent high tenacity reinforcing organic fiber selected from the group consisting of polyester and polyamide, and (c) 80 to 52 weight percent inert filler.
