PRELIMINARY INVESTIGATION ON THE DYNAMIC COMPRESSION PROPERTIES OF THREE-DIMENSIONAL (3D) CARBON FIBRE COMPOSITES

摘要

3D carbon fibre composites have been widely used in the aerospace and automobile industry,because this material is thermostable and wearable.There were much research on material manufacture and mechanical properties under static load condition,but the studies were relative fewer under dynamic loading.So the dynamic mechanical properties were obtained by SHPB compression experiment to 3D carbon fibre composites,the dynamic compression mechanical properties and the dynamic compression failure strength under different strain rate conditions were also gained in this paper.The experiment results indicate that this material was sensitive to strcss rate.In addition,the improvement of dynamic compression experiment to composites has been discussed to gain the credible results.
