Beschreibung
Zusammenfassung:	Epoxy resin compositions for fiber-reinforced composite materials comprise at least the constituents ÄAÜ an epoxy resin comprising 70 parts by weight or more, per 100 parts by weight of the epoxy resin, of a bi-functional epoxy resin, ÄBÜ fine particles comprising a rubber phase and substantially insoluble in epoxy resins and ÄCÜ a curing agent. The compositions are suitable for prepregs for production of fiber-reinforced composite materials having high impact resistance and heat resistance.
