摘要整理
树脂传递模塑（RTM）技术广泛应用于汽车、船舶和航空航天领域。在零件开发初期阶段，需要评估设计和生产关键决策对最终成本的影响，这促进了数值仿真的广泛应用。准确的RTM分析的主要难点在于所涉及材料的可靠表征。本文提出了一套经过验证的材料表征方法，该方法可在ESI PAM-RTM软件中实现并进行数据处理。通过实验研究了增强体渗透率和树脂粘度的测量方法，并对实验结果进行了详细讨论。最后，将获得的材料数据导入软件进行RTM工艺仿真，并与实验结果进行对比验证，以确认所述表征方法的有效性和可靠性。该研究为RTM工艺的数值模拟提供了系统的材料参数获取方案，有助于提高仿真预测精度，支撑RTM零件的设计优化和工艺参数确定。
