摘要
为了研究可回收环氧树脂R与风电叶片中常规环氧灌注树脂的区别,采用真空灌注工艺制备了玻璃纤维增强可回收热固性复合材料,对比分析了树脂之间的材料性能以及其复合材料之间的力学性能.结果表明,可回收树脂R的粘度与常规灌注树脂相近,适用期长于常规灌注树脂,适用于风电叶片的真空灌注工艺;放热峰出现时间略早于常规灌注树脂,有利于减少生产工时;其本体性能、复合材料力学性能与常规灌注树脂大体相当;可回收树脂R与常规灌注树脂的之间具有良好的界面性能,表明该树脂可以通过先制备部件然后整体灌注成型的方式制造大型复合材料制件.
Abstract
To explore the distinctions between recyclable epoxy resin R and traditional epoxy resin employed in wind turbine blades,a vacuum infusion method was employed to fabricate glass fiber-reinforced recyclable thermosetting composites.A comprehensive comparison and analysis of the material properties of the resins and the mechanical properties of their respective composites were conducted.The findings revealed that the viscosity of recyclable resin R closely resembled that of the conventional resin,while exhibiting a more extended pot life,rendering it suitable for the vacuum infusion process in wind turbine blades.The onset time of the exothermic peak was slightly earlier than that of the conventional resin,which proved advantageous in reducing production time.Both the bulk and mechanical properties of the composite generally paralleled those of the conventional resin.The favorable interfacial properties between recyclable resin R and conventional resin suggested the potential for manufacturing large composite parts by pre-preparing the components and subsequently executing the overall infusion process.
