The paper aims at the problems of inaccurate positioning of part, mould deformation at high temperature condition, and deformation of component surface in the process of composite materials. Laser tracker and laser radar equipment are used to detect and analyze the physical and technological process of composite materials. The solutions that digital detection technology is used for auxiliary locating and guiding assembly, applied for surface inspection of product and mold, and conducting manufacturing are put forward, and effectively improve the quality of composite materials.
