摘要: 采用真空辅助树脂传递模塑工艺(VARTM)制备了玻纤增强复合材料,测试表征了复合材料在不同温度及湿热环境下的力学性能的变化规律,简单分析了玻纤增强复合材料在不同条件下力学性能变化的原因,结果表明,在-50~150℃范围内,随着温度的升高,玻纤增强复合材料的力学性能呈下降趋势,其下降主要是由树脂的性能变化引起的;长时间的湿热环境也可引起力学性能的降低,这主要是由树脂与纤维的界面受到破坏引起的。温度和湿热对玻纤复合材料力学性能的影响研究为玻纤增强复合材料在工程上的应用提供了技术支撑。

Abstract: Samples of glass fiber reinforced composite are prepared by vacuum aided resin transfer molding process, and the influences of temperature and humid heat environment on mechanical properties of glass fiber reinforced composite are evaluated. The results show that, the aggregation state of the resin changes from glassy state to elastic state with the increasing of temperature during -50~150℃, and the mechanical properties of glass fiber reinforced composite decrease. Similarly, the mechanical properties also decrease with the increasing of test time in humid heat environment. This phenomenon is suggested to be caused by the damage of interface between resin and fibers. This study provides technological support for the engineering-application of glass fiber reinforced composite.
