This paper introduces a new numerical framework that speeds up calculations and demonstrates modeling methods for two critical factors in composite profile manufacturing processes. The research shows that pulling force can advance die detachment and reduce swelling, while the initial compressive stress state has the opposite but more significant effect.
Process-induced stress and deformation are critical factors when ensuring product quality and structural integrity of composite profiles manufactured using thermoset pultrusion processes. In this paper, we present a new steadystate 3D-Eulerian numerical framework that enables 9?35 times faster computations compared to the current state-of-the-art quasi-static 3D-methods. In addition, we show how process-induced effects from the profileadvancing pulling force and an initial compressive stress state can be modelled. We demonstrate in theoretical parameter studies that the pulling force advances die-detachment and reduces die-swelling, while the initial compressive stress state has the opposite but a more pronounced effect.
