Abstract In this study, fatigue behaviour of angle plies woven glass fiber reinforced polymer (GFRP) composite laminates has been investigated. Tension-tension fatigue tests were carried out under different maximum applied stresses that varied in the range of 50 - 90% of the respective ultimate strength of the laminates. Damage development in the form of debond zones and their growth was monitored. The results of the study are presented in terms of stress-strain curve, Wӧhler curve, delamination growth, total dissipated energy, dynamic modulus, and creep strain, respectively. (0°/90°) and ±15° laminate witnessed global damage while localized damage occurred in (±30°)8, (±45°)8 laminate.

编织 GFRP 角层板的疲劳寿命和损伤演变

摘要 在这项研究中，研究了角层编织玻璃纤维增​​强聚合物 (GFRP) 复合层压板的疲劳行为。拉伸-拉伸疲劳试验是在不同的最大施加应力下进行的，这些应力在层压板各自极限强度的 50-90% 范围内变化。监测脱粘带形式的损害发展及其增长。研究结果分别以应力-应变曲线、Wӧhler 曲线、分层增长、总耗散能、动态模量和蠕变应变的形式呈现。(0°/90°) 和 ±15° 层压板见证了整体损坏，而 (±30°)8、(±45°)8 层压板发生了局部损坏。
