Explanation

Test method for measuring the residual strength of composite materials laminate after impact. Most of them measure the compressive strength after impact. After the impact of composite materials laminate, matrix cracking, fiber fracture or delamination and other damages will occur to varying degrees, and some strength will be lost. The impacted samples will be subjected to compression tests to measure their residual strength, so as to estimate the remaining service life of composite materials, which will provide valuable reference data for determining the damage tolerance of composite materials and conducting damage tolerance design.
