摘要: The incorporation of 2 to 35 .mu.m particles of a differentially soluble engineering thermoplastic into heat curable epoxy resin systems significantly increases the toughness of such systems without loss of other desirable properties. These toughened epoxy resin systems are useful in preparing carbon fiber reinforced composites having compression strength after impact (CAI) of greater than 45. Ksi 310 MPa after a 1500 in-lb/in impact.
