摘要

Composite materials are widely used in the aerospace field due to their excellent properties. However, the curing deformation of the composite part will occur in the forming process, which will cause adverse effects on the forming part, such as the decline of precision and so on. This paper introduces the thermochemical model of composite parts and the influence mechanism of heating rate, curing temperature and demolding temperature in temperature curve on curing deformation, and simulates the curing process of a complex curved part based on ABAQUS finite element simulation software. The correctness of the simulation model is verified by comparing the digital measurement results. Based on the optimized temperature and demolding rate, the appropriate temperature was obtained.
