Scope

This document specifies the method principle, test specimens, test conditions, test equipment, test procedures, result calculation and test report of the compression performance test of fiber-reinforced plastic laminates after impact. This document applies to the determination of the post-impact compressive strength, post-impact effective compressive modulus and post-impact ultimate compressive strain of continuous fiber-reinforced plastic laminates with balanced and symmetrical plies.
