Abstract：By combining composite microstructure optimization with structure optimization, an integrated optimization design of structure and material of composite guide vane was developed. With the microstructure analysis model of plain weave braided composite, micromechanical finite element method was used to predict mechanical property, thermosetting coupling method was used to analyze turbine guide vane. During integrated optimization of structure and material procedure, design variables include microstructure parameter and macrostructure parameter, and the objective was mass of vane, also required to satisfy stress and displacement constraints.
