Front Profile

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.

The Steady flow simulation to selected the delta wing model for different angles of attack in the Maher number.The law of flow field changes with the angle of attack is gotten.Through the FLUENT simulation,The variation tendency of coefficient of lift and drag in the different angle of attack is gotten.Further reveals the change rule of Maher number, pressure, velocity and other parameters in the different angle of attack.With increasing angle of attack, Maher number distribution is sparse of the same position increases and the greater numerical.the distribution of velocity vector is sparse of the same position increases and the greater numerical.the pressure distribution is sparse of the same position increases and the greater numerical.
