摘要: 针对碳纤维/酚醛树脂蜂窝复合材料树脂传递模塑(Resin Transfer Molding,RTM)成型工艺,运用仿真和试验方法对树脂充模过程进行研究。首先测试了碳蜂窝预制体及酚醛树脂材料参数,然后运用PAM-RTM软件对不同流道设计、不同注射压力工况下树脂充模过程进行了仿真模拟。根据仿真结果,分析了树脂充模时间、充模路径、模腔内树脂流速分布、压力分布等树脂流动行为。仿真结果显示,流道设计为4个注胶口、1个或4个溢胶口,注射压力在0.3~0.5 MPa范围内,是比较理想的工艺参数设置。最终通过试验对仿真结果进行了验证,证明该仿真方法对工程应用具有一定的指导意义。

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.
