Abstract: Resin matrix composites, due to their excellent physical and chemical properties, are widely used in aerospace, automotive, and shipbuilding industries. The curing deformation process directly impacts the performance and reliability of the components. In this study, an L-shaped component made of thermoset resin matrix composite 3234/T300B is selected as the research object. A finite element analysis model is established, and Abaqus is used to simulate the curing process, analyzing the effects of curing temperature and lay-up angle on the curing deformation of the L-shaped component. First, the curing deformation behavior of the L-shaped component under different curing temperature regimes is investigated to determine the optimal curing temperature. Then, by changing the layup angle at this temperature, the influence of the layup angle on curing deformation and functional integrity was studied. The research results can provide a reference for the optimization of the curing process and engineering structural design of resin-based composite L-shaped components.
