Abstract

Experimental studies on the compressive behavior of composite laminates after low velocity impact was carried out with two test methods. One is SACMA Standard, and the other is a small dimensional specimen test method. Impact damage distributions, compressive failure process after impact, quasi-static indentation and compression of laminates with a hole were brought into comparison between these two test methods. The results showed that there is a great difference between these two test methods. Compressive behavior of laminates after impact varies with different test methods. Residual compressive strength of laminates after low velocity impact measured with SAC-MA Standard can reflect stiffness properties of composite resins more wholely than that measured with the other method can do. Small dimensional specimen test method should be improved on as an experimental standard of compressive strength after impact.
