摘要:
Z-pins植入平纹编织C/SiC陶瓷基复合材料层压板能提高层间I型断裂韧性.作为一种一体化设计的新型材料,Z-pin 增强陶瓷基复合材料具有重要的应用前景.研究Z-pins 增强陶瓷基复合材料的层间断裂韧性对于指导材料的设计与应用具有十分重要的理论意义和实用价值.基于离散弹簧-悬臂梁模型研究了Z-pins 直径、Z-pins 间距、单位厘米宽度上Z-pins 个数对平纹编织陶瓷基复合材料I 层间断裂韧性的影响.结果表明:增加Z-pins 直径、减小Z-pins 间距和增加单位厘米宽度上Z-pins个数可以提高Z-pins增强平纹编织C/SiC 陶瓷基复合材料I 型层间断裂韧性.
Abstract:
Interlaminar fracture toughness of mode I is improved by Z-pins insertion into woven C/ SiC ceramic matrix composites. As integratedly designed new materials, Z-pins reinforced ceramic matrix composites (CMCs) have wide application. The researches in interlaminar fracture toughness of Z-pins reinforced CMCs is very important both theoretically and practically for guiding the design and application of materials. Based on discrete spring-cantilever beam model, the effect of the diameter and the spacing of Z-pins and the number of Z-pins per cm width on mode I delamination fracture toughness were investigated. Conclusions are shown as following: Increasing diameters of Z-pins, and reducing spacing of Z-pins and increasing the number of Z-pins per cm width can improve mode I delamination fracture toughness of woven C/ SiC ceramic matrix composites.
