通过树脂传递模塑（RTM）工艺制造聚合物复合材料涉及将反应性聚合物树脂浸渍到具有预先放置的纤维增强物的模具中。RTM工艺条件的确定需要了解各种参数，如材料特性、模具几何形状和模具填充条件。整个RTM工艺的建模为分析重要参数之间的关系提供了工具。基于控制体积有限元法，建立了RTM充模过程的非等温三维计算机模拟模型。该模型将能够模拟模具填充在模具复杂的三维几何形状。RTM工艺的数值研究结果表明了该模型的应用。
The manufacture of polymer composites through the process of resin transfer molding (RTM) involves the impregnation of the reactive polymer resing into a mold with preplaced fibrous reinforcements. Determination of RTM processing conditions requires the understanding of various parameters, such as material properties, mold geometry, and mold filling conditions. Modeling of the entire RTM process provides a tool for analyzing the relationship of the important parameters. This study developed a nonisothermal 3-D computer simulation model for the mold filling process of RTM based on the control volume finite element method. The model will be able to simulate mold filing in molds with complicated 3-D geometry. Results of some numerical studies in RTM show the applications of the proposed model.
