摘要/Abstract

摘要： 采用拉拉单向剪切疲劳测试评价了叶片用环氧结构胶的疲劳性能,根据ISO 9664:1995,设定平均应力τ_m=0.35τ_R,频率为30Hz,振幅为2.0≤τ_a≤3.0MPa,测试环氧结构胶疲劳次数,得到S-N曲线并计算疲劳极限,研究胶层厚度、增韧剂及试样破坏形式等因素对疲劳性能的影响。本研究证明叶片用环氧结构胶疲劳性能指标对叶片设计和使用具有重要价值。

Abstract: This study give out the fatigue property of the epoxy structure adhesive used for wind power blade. According to ISO 9664:1995, the tensile shear fatigue character was tested periodicity vibration with the parameter of 30Hz frequency, τ_m=0.35τ_R mean stress, 2.0≤τ_a≤3.0 stress amplitude. The fatigue stress limit was calculated from the S-N curves obtained in the above test. In addition, we still studied thickness of the adhesive layer, proportion of flexibilizer, broken pattern of sample and other factors that would affect the fatigue property. The result shows that the fatigue property of the epoxy adhesive is very important to wind power blade's design performance and service life.

Key words: epoxy structure adhesive, fatigue testing, fatigue limit, S-N curve, factors fatigue testing
