Composites made using Resin Transfer Molding (RTM) processes have attractive properties to the aerospace and automotive industries because they can produce complex composite parts with good surface finishing. However, it still has a problem filling a large part with high fiber content at low injection pressure. Therefore, during the experiment, resin flow has to be the primary concern. This work presents a resin flow simulation of two types of mold where it will visualize the manufacturing process without actually doing it. Numerical simulation for the RTM manufacturing process is attempted by using Fluent-Ansys. It allows us to simulate the resin flow through the porous medium and obtain the total mold filling time and volumetric flow rate. It will lead to an explanation of the strength of the composite produced. Several assumptions and techniques are used to simplify the problem. Some variables, such as porosity and pressure injection, will be varied to see the effect of those variables on the RTM manufacturing process. According to the simulation result, porosity and pressure injection affect the RTM manufacturing process, especially for resin filling time and volumetric flow rate. The increase of porosity will increase the flow time, while pressure injection will decrease the flow. It happens due to how easy the resin flows through the porous medium, and the total area needs to be filled by the resin. This work is validated by comparing the obtained results with analytic solutions for a specific mold of Darcy’s law.

使用树脂传递模塑 (RTM) 工艺制成的复合材料对航空航天和汽车行业具有吸引力，因为它们可以生产具有良好表面光洁度的复杂复合材料零件。然而，在低注射压力下填充高纤维含量的大部分部件仍然存在问题。因此，在实验过程中，树脂流动必须是主要关注点。这项工作展示了两种模具的树脂流动模拟，它可以在不实际操作的情况下将制造过程可视化。使用 Fluent-Ansys 尝试对 RTM 制造过程进行数值模拟。它允许我们模拟树脂流过多孔介质并获得总模具填充时间和体积流量。这将导致对生产的复合材料的强度的解释。几个假设和技术被用来简化问题。一些变量，例如孔隙率和压力注射，将改变以查看这些变量对 RTM 制造过程的影响。根据模拟结果，孔隙率和压力注射会影响 RTM 制造过程，尤其是树脂填充时间和体积流量。孔隙度的增加会增加流动时间，而压力注射会减少流动。这是因为树脂很容易流过多孔介质，总面积需要被树脂填充。通过将获得的结果与达西定律的特定模型的解析解进行比较来验证这项工作。将变化以查看这些变量对 RTM 制造过程的影响。根据模拟结果，孔隙率和压力注射会影响 RTM 制造过程，尤其是树脂填充时间和体积流量。孔隙度的增加会增加流动时间，而压力注射会减少流动。这是因为树脂很容易流过多孔介质，总面积需要被树脂填充。通过将获得的结果与达西定律的特定模型的解析解进行比较来验证这项工作。将变化以查看这些变量对 RTM 制造过程的影响。根据模拟结果，孔隙率和压力注射会影响 RTM 制造过程，尤其是树脂填充时间和体积流量。孔隙度的增加会增加流动时间，而压力注射会减少流动。这是因为树脂很容易流过多孔介质，总面积需要被树脂填充。通过将获得的结果与达西定律的特定模型的解析解进行比较来验证这项工作。而压力注射会减少流量。这是因为树脂很容易流过多孔介质，总面积需要被树脂填充。通过将获得的结果与达西定律的特定模型的解析解进行比较来验证这项工作。而压力注射会减少流量。这是因为树脂很容易流过多孔介质，总面积需要被树脂填充。通过将获得的结果与达西定律的特定模型的解析解进行比较来验证这项工作。
