【Abstract】 The effect of gradient interface elastic modulus on the mechanical properties of the in-situ composite SiC_p/7075Al was analyzed using finite element software ABAQUS. The results show that the elastic modulus of the in-situ composite SiC_p/7075Al is related to the minimum elastic modulus of the interface gradient layer, and the elastic modulus increases with the increase of elastic modulus of the interfacial layer. The tensile strength of the composite increases with the increase of the elastic modulus of the interfacial layer, which is consistent with the change of elastic modulus of the composite with the gradient of the interface elastic modulus.更多还原
