摘要：

In previous research it was shown that through using preformed elastomer particle modified tackifier/binder, materials interlayered RTM composite structures could be manufactured. These interlayers resulted in excellent toughness improvements of traditionally brittle RTM materials. In this work, the effects of tackifier application and composition were investigated by modifying spray and powder epoxy tackifiers with polyamide 6 particles. The spray tackifier provided 30% improvements in Mode II interlaminar fracture toughness, and slight increases in the interlaminar shear strength without reducing the thermal properties. The powder tackifier showed a slightly lower performance increase due to a less homogeneous laminate structure. (C) 2001 Elsevier Science Ltd. All rights reserved.
