| Abstract: | A kind of high-density C/C composite reinforced by carbon fiber and axial carbon rod mix weaved 4D perform was prepared by the process of high-pressure pitch impregnation and carbonization.The thermophysical and ablative properties of the 4D C/C composites in axial direction were investigated.The results show that with increasing temperature the thermal diffusivity of the composites decreases exponentially,the specific heat increases,and the thermal conductivity decreases linearly,and the thermal constants ... |
