【Abstract】 The current studying condition about impacting experiments to composites was summarized briefly and the designing & working principle of the impacting machine were introduced detailedly.The property of the impacting machine was validated by experiment of impacting to some composite laminates,and the strength attenuation was analysed.The results shew that the impacting machine satisfies the request of collecting of data,and the impacting of low energy could lead vast laminate damage in the of the compsite laminates and the strength mostly reduced 35%.更多还原
