The “Boeing CAI” fixture is used to test the impact resistance of carbon and other fiber-reinforced polymer composite laminates. These materials are prone to great reduction in compressive strength, even when the impact load is insufficient to cause visible damage. The post-impact compression test is used to assess the relative performance of different composite laminates with different fiber matrix combinations. Laminates are subjected to low-velocity impact loading simulating tool drops and flying debris or may be subjected to an out-of-plane static indentation (ASTM D 6264 / D 6264M). Specimens then undergo a compression after impact (CAI) test on an electromechanical or servohydraulic testing machine.
