This study aims to explore the open-hole tension of fibre metal laminates containing thermoplastic particles experimentally and theoretically. In this regard, a vacuum bagging infusion process has been used to manufacture glass and glass metal laminates. Further, the tensile strength and damage failure modes were predicted using the Abaqus software, finite element analysis (FEA). This prediction was performed under a tensile test for notched composite laminates. The results of experimental tests indicated that the notch sensitivity is very important in terms of fracture and failures of composites. Furthermore, the findings show that the fibre metal laminates are less notch sensitive than glass composite laminates because of enhancing the composite ductility. In total, 28% of tensile strength decrease has been achieved after having holes for glass composites while the reductions were only 22%, 15% and 13% for glass composite laminates that have one, two and three aluminium layers, respectively. This reduction also becomes 4% for glass composite laminates that have one aluminium layer and thermoplastic particles and they exhibit typical ductile damage failures compared to other laminates. Further, the findings of numerical simulation for tensile strength and damage failure modes follow experimental results both qualitatively and quantitatively for notched composite laminates under tension loading.

热塑性颗粒对缺口纤维金属层压板机械性能和损伤失效的影响

本研究旨在从实验和理论上探讨含有热塑性颗粒的纤维金属层压板的开孔张力。在这方面，真空袋灌注工艺已用于制造玻璃和玻璃金属层压板。此外，使用 Abaqus 软件有限元分析 (FEA) 预测拉伸强度和损坏失效模式。该预测是在缺口复合材料层压板的拉伸测试下进行的。实验测试结果表明，缺口敏感性对于复合材料的断裂和失效非常重要。此外，研究结果表明，由于增强了复合材料的延展性，纤维金属层压板比玻璃复合材料层压板对缺口敏感度更低。玻璃复合材料开孔后，拉伸强度总共降低了 28%，而具有一层、两层和三层铝层的玻璃复合层压板的拉伸强度分别仅降低了 22%、15% 和 13%。对于具有一层铝层和热塑性颗粒的玻璃复合材料层压板，这种减少也变为 4%，并且与其他层压板相比，它们表现出典型的延性损坏失效。此外，拉伸强度和损坏失效模式的数值模拟结果在定性和定量上都遵循拉伸载荷下缺口复合材料层压板的实验结果。
