摘要：

The effect of interleaf sequence on impact damage and residual strength was analyzed in a graphite/epoxy laminates. The interleaf sequence created a unique laminated structure for advanced composites : graphite/non-toughened epoxy plies and PEK-C modified phase-inversion interply layers. The interleaf sequence also attributed the in-plane mechanical properties to the graphite/non- toughened epoxy plies and the damage resistance properties to the thermoplastic rich interlayer. It was found that the interaction between the two concepts can determine the post-impact behavior in the laminates.
