摘要：

This study investigated the damage tolerance and damage evolution of the compressive failure of a non-woven flax composite using compression after impact (CAI) tests. The effect of impact energy and influence of factors, such as impact shape, delamination area, and impactor penetration, on compressive behavior was studied. The effect of impact shape and the impact energy on the residual strength was investigated and then correlated to the impact-induced damage, previously validated. An impact energy threshold of 3 J has shown a significant effect of the studied factors on the residual strength, in addition to a clear effect of the residual damage on the composite failure under the compression loading.
