| 摘 要： | 碳纤维平纹编织物和穿透厚度的碳纤维Z-pins制作的预成型体,通过化学气相渗透工艺制备了Z-pins增强平纹编织C/SiC复合材料。采用双缺口剪切压缩试验测定了Z-pins增强平纹编织C/SiC复合材料的层间剪切强度,通过断口的电镜照片分析了层间剪切的破坏机理。研究了Z-pins个数对层间剪切强度的影响。结果表明:与未增强陶瓷基复合材料相比较,当Z-pins个数达到一定数量时,Z-pins插入能够提高层间剪切强度,层间剪切强度随Z-pins个数的增多而增加。Z-pins插入改变了陶瓷基复合材料的层间破坏机理,使层间织物与基体的脱离变为Z-pins的剪切破坏和层间织物与基体脱离的双重破坏机制。

| Abstract: | A preform consisting of plain-woven carbon fabric and Z-pins made of through-thickness carbon fiber bundles was prepared and then the Z-pin reinforced plain-woven C/SiC composite was fabricated by a chemical vapor infiltration.Double-notched shear compression tests and scanning electron microscopy were used on Z-pin reinforced plain-woven C/SiC ceramic matrix composite to measure interlaminar shear strength and to analyze fracture mechanism of the interlaminar shear,respectively.Effect of the number of Z-pi... |
