    摘要:

    研制开发出了一种低黏度、高活性、高性能的室温RTM 成型用树脂体系———R602,其凝胶温度
    为105℃,固化温度125℃,后处理温度175℃,Tg 为178℃;该树脂体系室温黏度较低,适用期在50 h 以上;固
    化产物和复合材料具有优异的综合力学和抗吸水性能,树脂的拉伸强度为97. 2 MPa,断裂延伸率为4. 12%,弯
    曲强度为162. 6 MPa。SEM 结果显示R602 树脂体系对纤维具有很好的浸润性。

    Abstract:

    This paper introduce a new R602 resin system for room temperature RTM process, which have low
    viscosity, high reaction activity and good properties. The resin began to gel at 105℃, to cure at 125℃ and to handle
    for better properties at 175℃, the Tg is 178℃. R602 resin system have low viscosity at room temperature and its potlife
    is more than 50 hour. The cured resin and composites of R602 resin system also exhibit excellent mechanical properties
    and hygroscopic resistance property. The tensile strength of the cured product is 97. 2 MPa, fracture elongation
    percentage is 4. 12%, and flexural strength is 162. 6 MPa. In addition, the SEM reveal that the impregnation of the
    R602 resin to fiber is very good.
