Abstract

Abstract: This paper establishes a multi-factor numerical model for the curing process of composite materials, exploring the temperature distribution of parts during resin curing using a thermo-chemical coupled heat transfer model. A constitutive model based on instantaneous linear elasticity theory, considering the evolution of material parameters, was used to describe the mechanical behavior of the material during the phase change process, predicting the curing deformation trend of end-rib honeycomb sandwich components. The reliability of the model was validated through experimental results. Based on the simulation analysis results, the tool surface was optimized. A comparative analysis was conducted between the parts prepared using the optimized tooling and the theoretical part surface. After tool optimization, the maximum deformation of the molded part’s surface compared to the theoretical part dimensions was reduced by 86.98%.

Key words: composite materials, cure deformation, finite element simulation, mold optimization, sandwich structure
