A Distribution Medium Considered Resin Flow Simulation Model for Vacuum Infusion Molding Process
摘要整理
Based on the flow characteristics of resin in fiber perform, a simulation model considering distribution medium was developed, and impregnation of fiberglass reinforced resin matrix composites was numerically simulated. The fiberglass layer thickness on VIMP microscopic impregnation was analyzed in simulation. The results show that increasing fiberglass layer thickness can reduce the flow velocity of the resin and the resin flow front profile approximates a straight line type, so the fluctuation is small, and the final product has few dry spots; reducing the glass fiber layer thickness can improve wetting speed but resin flow front profile approximates a parabolic type, so the fluctuation is large, and the final product has more dry spots, the resin flow front profile can provide guidance for prediction and optimization of the infusion process.
