In order to meet the development of composite materials in the aerospace field of replacement. Aiming at the carbon fiber composite material preparation process in the hand-layup molding process molding parts porosity is too large, the mechanical properties of the parts is low and other problems. This paper introduces TRIZ theory to analyze the problematic conflicts in the hand-layup molding process.The problems are decomposed into components and logically connected before and after, and the problems are analyzed by applying innovative thinking to system analysis, including functional analysis, cause and effect analysis, and the nine-screen analysis method. Then the final ideal solution, ARIZ algorithm, and contradiction matrix in TRIZ tool are applied to derive an innovative and optimized solution in conjunction with the steps of the hand lay-up molding process. Ultimately, the goal of reducing porosity and applying it to modern hand lay-up molding composites is achieved.
