摘    要:试验研究了三维机织C/C-SiC复合材料的弹性性能, 基于复合材料的扫描电镜(SEM)照片, 分析了材料的细观结构的特点, 并提出了一系列的假设, 建立了三维机织C/C-SiC复合材料的细观力学模型, 利用均匀化方法预测了复合材料的弹性常数, 分析了材料的弹性性能随经纱倾斜角的变化规律。结果表明: 预测结果与试验结果吻合较好, 表明该预测模型和方法的正确性; 随着经纱倾斜角的增加, 经纱方向的弹性模量降低, 其它方向的弹性模量均增大, 但面内剪切模量和厚度方向的弹性模量增幅很小。 

关 键 词:三维机织C/C-SiC复合材料   弹性性能   预测   均匀化方法

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 ...
Keywords:three-dimensional woven C/C-SiC composite  elastic properties  prediction  homogenization method
