Abstract: Composites are widely used in the aircraft structure and its damage tolerance property is an important index of aircraft design. An empirical prediction formula for compressive strength of composite laminate after impact based on energy was formulated. With experimental studies, influence factors for compressive strength were analyzed to determine the forms and parameters of the empirical formula, and the predicted results were compared with experimental data as well. The predicted results of the empirical method accord well with sufficient experimental data by general verification. The results indicate that it is a convenient and efficient engineering prediction method for compressive strength after impact. In addition, the experimental results indicate that the relationships between compressive strength and impact energy are suitable for piecewise power function fitting. Impact energy, thickness of laminate, ply proportion and material tenacity have obvious effect on compressive strength of composite laminate after impact, while the diameter of impactor has no significant effect.
