| Abstract: | The elastic properties of three-dimensional woven carbon fiber reinforced C-SiC binary matrix(3D woven C/C-SiC) composite were studied.Based on the scanning electron micrographs(SEM) of 3D woven C/C-SiC composite,the micro-structure was analyzed,a series of assumptions were proposed,and the micro-mechanical model was founded.The elastic properties of 3D woven C/C-SiC composite are evaluated with homogenization method.The variable regularity of elastic modulus is also studied as the warp angle increases.The ... |
