树脂传递模塑制品的缺陷控制及流程优化

Defect Control and Process Optimization of Resin Transfer Molding Products

树脂传递模塑(RTM)是一种高效的树脂基复合材料成型方法,其中RTM工艺的缺陷控制方法是目前研究的主要方向。首先介绍了RTM工艺和其传统工艺流程,然后通过试验成型RTM制品,分析制品缺陷及其产生机理,提出缺陷控制的4项原则和改进的工艺流程,最后进行论证试验。试验证实改进工艺解决了RTM制品中的气泡、滑移和干斑缺陷,对RTM工艺的研究和工业实践具有一定的指导意义。

RTM（Resin transfer molding） is a high performance molding method for producing the resin matrix composite, and the method of RTM defect control is the main research direction in this field. RTM technology and the traditional process are introduced, then by the means of experimental molding of RTM products, analysis of product defect and its mechanism, four defect control principles and improved process are proposed. Finally, the demonstration test is carried on. The test proves that the improved process has solved the defects such as air bubbles, slip and dry spots of the RTM products, and has the certain instruction significance to the research and industrial practice on RTM.
