利用考虑界面反应层的有限元模型,分析了界面反应对复合材料界面剪切强度的影响。有限元预测得出,界面剪切强度随着界面反应增强而增大。并且,建立了界面反应层厚度和界面剪切强度的关系式。
The finite element model, which considered the interracial reaction layer was developed to evaluate interracial shear strength of titanium matrix composites (TMCs) and analyze the effect of interface reaction on interracial mechanical properties. The results show that the interracial shear strength of SiC/Timetal-834 evaluated is about 500 MPa, and that the interracial shear strength increases as the interracial reaction enhances. Moreover, the relationship between the thickness of the interracial reaction layer and the interfacial shear strength is built.
