Abstract

The formation of voids during processing of glass fiber reinforced polymer may have a significant effect on the mechanical properties. In this paper, CFD simulation has been used for modelling of resin vacuum infusion process of fiberglass reinforced plastic pultruded sheet. The simulation results show that the velocity of resin flow decreases gradually as the infusion process continues, and reaches stability finally. The pressure gradient in the horizontal flow channel is an order of magnitude larger than the normal channel. The quality of the resin infusion process is closely related to the velocity of resin flow. The regions where the infusion defect occurs always have a lowest resin flow rate. The pressure gradient field in resin flows involves the infusion defect which usually appears in the area with a lower pressure gradient. This article research will provide references for the resin infusion process of bulk composite with fiberglass reinforced pultruded sheet.
