Glass laminate aluminum reinforced epoxy (GLARE) is a vital class fiber metal laminates (FMLs) and advanced aircraft material. Despite the ongoing research and utilization of FMLs in applications like structures and aircraft, the weakness is particularly the materials’ delamination. This phenomenon is still observed as the primary confinement for an increased and efficient utilization of the materials. In this study, interlaminar shear strength (ILSS) of GLARE composite is improved through many chemical treatments and the anodizing process. T-peel test characterizes the ILSS through the ASTM D1876–08 standard. The numerical model was also developed to predict the ILSS of GLARE laminates and their performance. Results show that the anodizing process enhances the ILSS of GLARE composite. Anodizing makes the aluminium surface porous and improves glass fiber's adhesion with Aluminum surface. The numerical models successfully predict experimental results for un-anodized samples.

通过 T 剥离试验，阳极氧化工艺对 GLARE 复合材料层间剪切强度的影响：实验和数值方法

玻璃层压铝增强环氧树脂 (GLARE) 是一种重要的纤维金属层压板 (FML) 和先进的飞机材料。尽管 FML 在结构和飞机等应用中的研究和利用正在进行，但其弱点尤其在于材料的分层。这种现象仍然被认为是增加和有效利用材料的主要限制。在这项研究中，GLARE 复合材料的层间剪切强度 (ILSS) 通过许多化学处理和阳极氧化过程得到提高。T 型剥离测试通过 ASTM D1876-08 标准表征 ILSS。还开发了数值模型来预测 GLARE 层压板的 ILSS 及其性能。结果表明，阳极氧化过程提高了 GLARE 复合材料的 ILSS。阳极氧化使铝表面多孔，提高玻璃纤维与铝表面的附着力。数值模型成功地预测了未阳极氧化样品的实验结果。
