| Abstract: | The tensile properties of 3D carbon/carbon composite at ultra-high temperature have been studied based on rapid resistive self-heating technique. This paper also describes a mini-finite element model for evaluation of high temperature elastic modulus of 3D C/C composite and the variation of tensile properties with substrate parameters such as xy- woven layers, fiber boundles and fiber spacing was analyzed.The results predicted suit the experimental data well. |
