摘要/Abstract

摘要： 设计了四种预固化制度对风电叶片用树脂静力性能和单向织物的复合材料疲劳性能进行了研究,研究结果表明预固化温度对环氧树脂基体和复合材料的静力学性能影响不显著,但对复合材料的疲劳性能具有较大的影响,通过实验测试验证了预固化温度对疲劳性能m值的影响趋势,结合叶片制造不同预固化温度对复合材料叶片制造出现的泛白现象进行了分析,明确了玻纤增强树脂基复合材料的制造固化过程的温度边界。

Abstract: This paper studies the static properties of resin and fatigue performance of unidirectional fabric composite material at four different pre-curing temperatures. The results show that the pre-curing temperature has no effect on the performance of epoxy resin and FRP statics mechanical properties, but has a great influence on the fatigue properties of the fiber reinforced epoxy resin. The relationship of precuring temperature and the fatigue m value trend is verified by experimental test, different precuring temperature on composite blade manufacturing blushing phenomena are analyzed. In this paper, the temperature boundary is proposed for the curing process of glass fiber reinforced resin matrix composites.

Key words: wind turbine, precuring temperature, fatigue properties, crack, whitening, composites
