| 摘 要： | 对三维编织C/SiC复合材料进行剪切试验和压缩试验,得到两组试验的载荷位移曲线以及剪切强度和压缩强度.实验发现,相同宽度的剪切试件,剪切厚度小的试件剪切强度比剪切厚度大的试件高;相同剪切截面的剪切试件,XY剪切强度高于YX剪切强度;横截面积相同,高度不同的压缩试件在X方向的压缩强度相差不大.对三维编织C/SiC复合材料热端构件进行分析,结果表明,构件的压缩强度和剪切强度都能满足强度要求.

| Abstract: | Shear and compress tests of 3-D braided C/SiC composites were carried out,and load-displacement curves and shear strength,compress strength were gained.The following conclusions were reached.With the same width,average shear strength of specimens of greater height was less than that of specimens of lower height.With the same shear cross section area,average shear strength of XY shear specimens was greater that of YX shear specimens.And with the same cross section,compress strengths in X direction of specimens with different height were almost the same.FEA results revealed that maximum shear stress and compress stress of 3D braided C/SiC structure were less than material's strength. |
