Research of Mechanical Properties of 3D Braided Composite Materials

The stretching,compression and bending experiments have been done for the 4 step 3D braided composites The principal mechanical properties and destruction rule of 3D braided composites are obtained The results of these experiments show that the 3D braided composites have good mechanical properties,and the braiding process and the braiding structures have a great influence on them These results can provide an experimental basis for further studies on the failure problems of braided composites
