    为探讨颗粒增强低熔点金属基复合材料的性能和断裂特性,扩大锌合金的应用范围,本项工作采用流变铸造法制备了SiCp/Zn,Al2O3p/Zn基复合材料,对该材料进行了冲击韧性、弯曲强度、压缩强度等性能测试,观察了其断口形貌,分析了其断裂特性,提出了此类复合材料的断裂模式。
    In this paper, the fracture characteristic of a Csf/LAS composite with Li2O-A12O3-SiO2 glass-ceramic as matrix reinforced with short carbon fibres was studied. The results show that, with the increase of loading rate, the fracture work rwof of the composite decreas-es, while the bending strength increases first and then decreases. The bending strength reaches its maximum when the loading rate is 500 MIPa/s.
    对短切碳纤维增强Li2O-Al2O3-SiO2玻璃陶瓷基复合材料(Csf/LAS)断裂特性进行了研究,结果表明:随加载速率增加,材料的断裂功rwof降低,而材料的抗弯强度先增加后降低.当加载速率为 500 MPa/s时,材料的抗弯强度最大.用扫描电镜观察.当加载速率较低时,有明显的纤维拔出;
