In order to analyze the influence of the adhesive layer on the surface quality during the manufacturing process of the sandwich structure, modeling and analysis are carried out in the finite element analysis software ABAQUS with PMMA as the main research object. During the hot-pressing manufacturing process of the sandwich structure, the influence of the adhesive on the surface quality is studied through the 2 processes of heating and pressurization. The results show that when only the heating process is considered, due to the viscoelasticity of the adhesive, PMMA will become softer as the temperature rises, which will lead to an increase in the surface waviness; when only the pressurization process is considered, the viscoelasticity has almost no effect on the surface waviness. When the hot-pressing is coupled, the surface waviness will be greater than that when only heating or pressurization is considered alone; the softer the adhesive, the greater the surface waviness. By adjusting the characteristics of the adhesive, the surface quality of the sandwich structure can be effectively controlled, thereby improving the overall quality of the product.
