| 摘 要： | 通过开发计算机程序与有限元/控制体积分析软件,能够实现对任意复杂三维形状复合材料构件的造型和RTM工艺充模过程的模拟。研究了改变工艺参数时工字孔平板的RTM工艺模拟结果和实验结果,两者基本保持一致;证明了恒压注射情况下,充模时间与注射压力、渗透率成反比,与树脂粘度成正比;也证实了该模拟软件确实可用于预测树脂流动模式以及成型效率,为RTM实际工艺设计与优化提供了有效的技术手段。

| Abstract: | A developed computer code and a FEM/CV analysis software can combine to model any complex 3D composite parts and simulate the RTM mold-filling process. The simulation and experiments of I-shaped 2D plane with different processing parameters were investigated, and the results show that the mold-filling time is inverse proportion to pressure and penetrability, and direct proportion to resin viscosity. The experimental data are in good agreement with the numerical data, which validates that the simulation software is reliable to predict resin flow patterns and processing efficiency. The results can be further utilized to find the optimal processing conditions for RTM parts. |
