Abstract

Abstract: 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 under different channel designs and injection pressure conditions. Based on the simulation results, the resin flow behavior such as resin filling time, filling path, resin flow velocity distribution in the mold cavity, and pressure distribution 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 simulation results provides valuable guidance for engineering applications.
