Abstract:
A kind of high-density carbon/carbon composite reinforced by the carbon fibre and axial carbon rod mix weaved 3D 4-Directional perform is prepared by the process of high-pressure pitch impregnation and carbonization(HIPIC).The microstructure and fracture micrograph are studied with scanning electron microscopel(SEM)and optical microscope(OM).The mechanical properties of the material are examined by tensile tests,impact tests and three-point bending tests,respectively.The results show that the 3D 4-directional carbon/carbon composites have fine structure and favorable mechanical properties and the primary failure mode of the materials is pseudo plastic fracture.
