This study experimentally investigates the use of stainless-steel woven wire mesh (SSWWM) as a patch material for repairing damaged glass fibre-reinforced (GFR) composite laminates. The effects of several factors on the three-point bending (3PB) behaviour of the parent laminate were examined, including the repair method (the plugging of open hole and the external patch repair), the mesh count of the SSWWM, and the number of SSWWM layers. According to the findings, all parameters considered in this study play a pivotal role in 3PB behaviour. Employing SSWWM as a patch material can recover 66.02-129.2% of the undamaged 3PB failure load, depending on the repair method, mesh count of the SSWWM, and number of SSWWM layers. Overall, decreasing the mesh count and increasing the number of SSWWM layers and applying an external patch repair method yield better results in terms of failure load and patch efficiency. This can be attributed to the increased wire diameter, improved bending rigidity, and better load distribution over a wider area. The SSWWM bridges the damaged zone, ensuring effective load transfer between the patch and parent laminate while preventing crack propagation. Utilising SSWWM as a patch material provides a quick, reliable solution for damage scenarios in engineering applications.
本研究通过实验研究了不锈钢编织丝网（SSWWM）作为修补受损玻璃纤维增强（GFR）复合材料层压板的贴片材料的应用。研究了几个因素对原始层压板三点弯曲（3PB）行为的影响，包括修补方法（开孔堵塞和外部贴片修补）、SSWWM的目数以及SSWWM的层数。根据研究结果，本研究中考虑的所有参数在3PB行为中都起着关键作用。使用SSWWM作为贴片材料可以恢复未受损3PB失效载荷的66.02%-129.2%，这取决于修补方法、SSWWM的目数以及SSWWM的层数。总体而言，减少目数、增加SSWWM的层数以及采用外部贴片修补方法在失效载荷和贴片效率方面能产生更好的结果。这可归因于线径增加、弯曲刚度提高以及在更大面积上更好的载荷分布。SSWWM跨越受损区域，确保贴片与原始层压板之间有效载荷传递，同时防止裂纹扩展。在工程应用中，使用SSWWM作为贴片材料为损伤情况提供了一种快速、可靠的解决方案。
