摘要

We have investigated failure mechanisms of compression fatigue behavior of impacted composite laminates. We used the two kinds of composite materials; AS4/PEEK and UT500/Epoxy, in compression fatigue test and compared the results. The endurance for impact damage of UT500/Epoxy was lower than that of AS4/PEEK. And the S-N curve of unimpacted UT500/Epoxy specimen showed a gentler gradient than that of AS4/PEEK. But their S-N curves of impacted specimens were comparatively similar.
