Abstract: Consideration of the gap between squeezer rollers in wet filament winding, with the interlayer shear strength, porosity, and fiber volume fraction as performance characterization parameters for winding products. A response surface methodology to design wet filament winding experiments with three factors and three levels is employed, and the sensitivity of the gap between squeezer rollers on the performance characterization parameters is analysed. A multivariate regression predictive model that takes into account the gap between squeezer rollers along with various process parameters and different performance characterization parameters is established, revealing the influence of the gap between squeezer rollers on product performance under different conditions. Furthermore, the coupling effects of the gap between squeezer rollers with winding tension and winding speed on product performance mechanisms is analysed. Based on a multiple regression prediction model, a multi-objective optimization scheme is developed using the main objective method, and a winding experiment is designed. The results show that the optimized process parameter combination obtained through this method not only reduces the porosity of the winding product but also improves its mechanical properties, effectively enhancing the overall quality of wet-winding products.
