| 摘 要： | 树脂传递模塑成型（RTM）工艺是在一定温度及压力下把低黏度的树脂注入预先置有增强纤维的模具中,然后固化成型的一种复合材料液体成型方法。本文建立了RTM工艺充模过程的数学模型,并采用有限元/控制体积法实现了对复杂薄壁构件的充填模式、压力场和速度场的模拟。

| Abstract: | The resin transmission molding (RTM) process is that pours the resin with a certain temperature and under the pressure at the low viscosity to set in advanced enhancement textile fiber in the mold, then the solidif ication takes shape one kind of compound material liquid.This article has established the mathematical model of RTM filling mold process, and used the finite element/control volumetric method to realize the simulation of the filled pattern, the pressure field and the velocity field of the complex thin wall component. |

| Keywords: | composite material the resin transmission molding value simulation finite element/control volumetric method |
