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.

摘要： The incorporation of 2 to 25 .mu.m particles of a limited class of polyimides having appreciable nonaromatic character 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 after a 1500 in-lb/in impact.

摘要： The subject invention pertains to toughened thermosetting resin systems useful as structural adhesives and as matrix resins for thermosetting fiber-reinforced prepregs. These toughened resins employ a most minor amount of functionalized elastomeric particles having a T.sub.g of 10.degree. C. or below dispersed in a thermosetting base resin system.
