This instrumented drop weight impact tester is primarily designed for testing non-metallic materials. It is mainly used to determine the resistance to failure of various standard or non-standard composite plate-shaped specimens under impact loading. Upon completion of the test, the system can reproduce the instantaneous force-displacement-time curves of the impact process on a computer.
