摘要/Abstract

摘要： 为研究碳纤维增强树脂基复合材料构件固化过程的压力分布规律,搭建了以毛细管压力传感器为核心的压力在线监测系统,应用该系统在线监测得到了复合材料帽型加筋构件固化过程各关键部位的压力分布。在此基础上,分析了帽型加筋构件固化过程各部位压力分布受芯膜调型孔孔占比X_s的影响,研究了不同孔占比芯模固化帽型加筋构件的成型精度和微观质量。结果表明,当芯膜调型孔孔占比为0.099时,帽形加筋构件固化过程的压力分布均匀性较好,构件成型精度和微观质量较高。

Abstract: In order to study the pressure distribution of polymer matrix composite during its curing process, this paper builds a pressure online monitoring system with capillary pressure sensor as the core.With this system,the pressure distribution of the key parts of the curing process was obtained. The pressure distribution in each part of the hat-stiffened component curing process was analyzed by the influence of the rubber mandrel adjusting hole ratio. The forming precision and the microscopic quality of hat-stiffened component cured with different adjusting hole ratio were studied. The results show that when the adjusting hole ratio is 0.099, the pressure distribution of the hat-stiffened component during curing is better, and the forming precision and the microscopic quality of the component are higher.

Key words: composites, curing pressure distribution, online monitoring, forming quality
