ABSTRACT
Finite Element Analysis of the Pressure Behavior During the Pultrusion of Composites
| A common problem associated with the manufacture of composites is the formation of voids in the final product. The voids in the composite adversely affect the strength of the final product. A high pressure rise in the die inlet region can eliminate the voids. The elimination of voids can lead to a better quality final product. The purpose of this research is to determine the effect that various process control parameters have on the pressure rise during the pultrusion process. A numerical approach referred to as the Finite element method is employed in this study. Finite element analysis is used to investigate the effect of the process control parameters of pull speed, fiber diameter, and fiber volume fraction on the pressure rise in the pultrusion die region. |
