Abstract
The stress-strain curves and principal mechanical properties of the carbon/carbon composite reinforced by carbon fiber and axial carbon rod mix weaved 4D were obtained by means of the compression and bending experiments. The fracture micrographs of the material were studied by SEM, and the failure mechanisms of the material were analyzed. The results show that the 4D carbon/carbon composites have favorable mechanical properties, and the braid structures have a great influence on it. The axial compression properties of the material are excelled over radial ones, but radial bending properties are superior to radial ones. The compression specimens are crushed with toughness fracture character. The bending ones are destroyed by shear stress or delamination, and some fibers are drew from matrix.
