Abstract: Reinforced composite materials quickly rise to prominence in advanced material applications due to their lightweight nature as well as their exceptional resistance against high temperatures and corrosion. They are currently a focal point in researches related to advanced material science, such as high-speed rail technology and other emerging fields. This study aims to provide a more precise analysis of solidified dynamic physical simulations relating to composite components. In this study, we choose the COMSOL Multiphysics software to conduct comprehensive simulations on the temperature field and the solidification field of a C-beam structure. First, we establish simulation models about the temperature field and the solidification field of the C-beam structure. Second, we analyze the solidification dynamic physical process during the forming process of the composite material pressure vessel, using the numerical analysis of finite element under the preset attributes of the composite material molds and parts when the pressure vessel is formed. Finally, we acquire a deviation not above 2.5% through analyzing the simulation data. Meanwhile, this study proposes new directions on the optimizing the solidification process of composite material parts in pressure vessels through analyzing the temperature curves of the C-beam structure on five feature points.
