Abstract: Aiming at the application requirements of extreme environment, extreme lightweight and high in-tegration of Aerospace precision structural parts, the design idea of functionally gradient materials is applied to the design and development of SiC_P/Al composites. Based on the parameters of mate-rial preparation method, gradient composition change, macro/micro gradient interface and material properties, the calculation model of gradient SiC_P/Al composites was established by ANSYS Workbench software. The interaction between material interface and stress was predicted by transient dynamic analysis method. The comprehensive evaluation method of gradient structure, mate-rial composition and material properties was established, which provided theoretical support and technical support for the future research of gradient functional structural parts and the develop-ment of aerospace precision structural parts.
