本文介绍了纤维毡预填充树脂注射成型充模过程的数值模拟和可视化实验结果。对由连续无规玻璃纤维毡和双向缝合玻璃纤维毡组成的各种毡堆进行了充模实验。在垫堆叠中使用两种不同的垫类型产生孔隙率和渗透性变化。这些渗透率变化的影响进行了研究，通过采取流动压力测量和观察的非反应性流体的流动前沿填充一个明确的丙烯酸模具，其中包含增强垫堆叠的进展。并对各试验进行了数值模拟。数值计算结果与实验测量结果进行了比较。
This work presents the results of numerical simulation and experimental visualization of the mold filling process in resin injection molding with preplaced fiber mats. The mold filling experiments were conducted with various mat stacks consisting of continuous random glass fiber mats and bidirectional stitched glass fiber mats. The use of two different mat types in the mat stack created porosity and permeability variations. The effect of these permeability variations was studied by taking flow pressure measurements and observing the progress of the flow front of a non-reactive fluid filling a clear acrylic mold that contained the reinforcement mat stack. Numerical simulation corresponding to each experiment was also carried out. The numerical results were compared to the experimental measurements.
