In this study, the adhesive characteristics of double cantilever beam specimens with the inhomogeneous adhesion materials due to tensile and out-of-plane shear fractures have been investigated. The experiments were conducted by applying a forced displacement rate of 3 mm/min at the upper position and fixing the lower position, while each experimental condition was maintained to be identical. In the tensile fracture of mode Ⅰ, the maximum reaction force was observed to be highest in the order of CFRP-Al, Al–Al_Foam, and CFRP-Al_Foam. The maximum energy release rate was highest in the order of Al–Al_Foam, CFRP-Al, and CFRP-Al_Foam. When the overall crack resistance curves were examined, all of the highest energy release rates could be seen to be produced at an early stage of cracking. In mode Ⅲ, the maximum reaction force was highest in the order of CFRP-Al, Al–Al_Foam, and CFRP-Al_Foam. The maximum energy release rate was observed to be highest in the order of CFRP-Al, CFRP-Al_Foam, and Al–Al_Foam. Considering that the higher reaction forces and energy release rates were produced in the specimen containing, it could be inferred that the use of a material with high rigidity increased the maximum strength of the adhesive.

在这项研究中，研究了双悬臂梁试样与由于拉伸和平面外剪切断裂而产生的不均匀粘结材料的粘结特性。通过在上部位置施加3 mm / min的强制位移速率并固定下部位置进行实验，同时保持每个实验条件相同。在模式Ⅰ的拉伸断裂中，观察到最大反作用力以CFRP-Al，Al-Al_Foam和CFRP-Al_Foam的顺序最高。最大能量释放率最高的顺序为Al–Al_Foam，CFRP-Al和CFRP-Al_Foam。当检查整体抗裂性曲线时，可以看出所有最高的能量释放速率都在裂纹的早期产生。在Ⅲ模式下 最大反作用力按CFRP-Al，Al-Al_Foam和CFRP-Al_Foam的顺序最高。观察到最大能量释放速率最高，依次为CFRP-Al，CFRP-Al_Foam和Al–Al_Foam。考虑到在包含样品的样品中产生了更高的反作用力和能量释放速率，可以推断出，使用具有高刚性的材料会增加粘合剂的最大强度。
