摘要
介绍了硅酸铝短纤维增强ZL109铸铝合金(Al2O3SiO2/ZL109MMC)的静态实验和冲击实验结果。给出了这种复合材料的静态强度、动态屈服强度和层裂强度并对实验结果进行了分析讨论。
Short fiber or particulate reinforced MetalMatrix Composites (MMC) are a class of advanced materials.These composites have extensive potential for use in aerospace and automotive industries due to their lower densities and superior mechanical properties.It is imperative therefore to study the strength behavior of such MMC.In this paper,we describe the results of quasistatic tensile and compression test,or of plate impact experiments conduced on a Al2O3·SiO2 short fiber reinforced ZL109 cast aluminum alloy.The tensile strength,compressive yield strength,dynamic yield and spall strength are presented.Discussion of the mechanical characterization of the Composite is given.
