摘要

本文研究了玻璃纤维增强聚合物(GFRP)复合材料试样在高周疲劳加载条件下的疲劳行为分析。因此，建议在材料开发过程中对制备的GRFP进行进一步研究后进行性能验证。本研究旨在评估制备的GFRP疲劳试样在高周疲劳载荷下的行为，并将其与现有研究进行比较。采用手工叠层法将GFRP疲劳试样制作成矩形平板，然后将其切割成28×2×0.2 cm的小尺寸疲劳试样。在不同的等幅载荷或在极限抗拉强度的40% ~ 80%之间的应力水平下，对5个平面试样进行疲劳试验，得到了制备的GFRP的应力-寿命曲线。结果表明，80%的高应力水平对GFRP疲劳寿命周期的缩短贡献最大。这一结果与以往的研究结果一致，并且在已发表的生命周期范围内，验证了制备的GRFP。一个叫做失效模量(Mf)的新参数可以用来量化一组特定的疲劳试验。

High-Cycle Fatigue Life Behaviour of Fabricated Glass Fibre-Reinforced Polymer

This study focuses on the fatigue behaviour analysis of glass fibre-reinforced polymer (GFRP) composite specimens under high-cycle fatigue loading conditions. Therefore, property validation is recommended in the material development process upon further investigation of the fabricated GRFP. This study aims to evaluate the behaviour of the fabricated GFRP fatigue specimen when subjected to high-cycle fatigue loads and compare it to existing studies. A GFRP fatigue test sample was fabricated using the hand layup process into a flat rectangular panel, which was then cut into a small dimension of 28×2×0.2 cm fatigue specimen. Fatigue tests were performed on five flat specimens at different constant amplitude loads or stress levels between 40% and 80% of ultimate tensile strength to obtain the stress–life curve for the fabricated GFRP. Results showed that the high-stress levels of 80% contributed to the most reduced fatigue life cycle of GFRP. This result is consistent with previous studies and lies within the published life cycle range, validating the fabricated GRFP. A new parameter called the failure modulus, or Mf, may be used to quantify a particular set of fatigue tests.
