摘要/Abstract

摘要： 复合材料多隔板框梁结构复杂,内外形精度要求高,本文研究了采用树脂传递模塑成型(RTM)工艺实现该类结构的精确制造。介绍了RTM成型模具的设计、预制体的制备及其注胶工艺的改进,并讨论了它们对于RTM制件质量的影响。结果表明,整体线型注胶口利于大型复杂结构的树脂注胶;适当增大注胶压力,并进行保压,有利改善制件表面质量;控制预制体和树脂中的气泡有利改善制件内部质量;预制体转角区增加额外填充材料可以避免该区域的富树脂及其脱落引起的表面缺陷。最后对其力学性能进行了测试分析。

Abstract: In the paper, a method of resin transfer molded(RTM)was introduced to produce a typical carbon fiber reinforced composites multi-clapboard frame girder. A design of the resin flow route,the fabrication method of the prefab part and some parameters of resin injection were discussed and proposed. Based on a series of experiment results, some conclusions were drawn. At first, the line resin inlet is more compatible to the great complex structures than the point one. Secondly, the raise and appropriate maintenance of injection pressure is in favor of the surface quality of parts. Third, the improvement of vacuum of prefab part and the elimination of air inside the resin is associated with the inner quality of RTM parts. Finally, the filling of extra fibers in the corner of prefab parts will avoid the surface defects caused by the local concentration of resin and its delamination. In the end, the mechanics of RTM parts were measured and discussed.

Key words: multi-clapboard frame girder, RTM, flow route
