摘要：

Interlaminar fracture toughness (IFT) characteristics of graphite/epoxy laminates were evaluated in tests on specimens with different tough adhesive interlays. An artificial interlaminar edge crack was forced to propagate under two modes: separation, and shear. Results indicated that the interlayer, located in front of an existing flaw, may increase IFT more than sixfold compared with an uninterleaved brittle-matrix composite reference. The effect was stronger in the separation mode than in the shear mode, and seems to increase with thickness of the interlayer.
