碳蜂窝液体成型工艺树脂充模仿真研究OA

The resin filling process of carbon fiber/phenolic resin honeycomb composite material RTM molding is studied using simulation and experimental methods.Firstly,the parameters of carbon honeycomb preforms and phenolic resin materials were tested,and then PAM-RTM software was used to simulate the resin filling process un-der different channel designs and injection pressure conditions.Based on the simulation results,the resin flow be-havior such as resin filling time,filling path,resin flow velocity distribution in the mold cavity,and pressure distri-bution was analyzed.The simulation results show that when the flow channel is designed with 4 injection ports,1 or 4 overflow ports,and the injection pressure is in the range of 0.3 MPa to 0.5 MPa,it is an ideal method for setting process parameters.Finally,the simulation results were verified through experimental methods,proving that the sim-ulation results provides valuable guidance for engineering applications.
