The failure load of single-lap steel joints (subjected to tensile force) with epoxy/nano-Al 2 O 3 adhesives was analysed experimentally. Spherical-shaped nano-Al 2 O 3 of diameter 23–47 nm and rod-shaped nano-Al 2 O 3 of diameter < 10 nm and length < 50 nm were included in the epoxy adhesive by wt% (0.5, 1.0, 1.5, and 2.0 wt%). Stress intensity factor of the adhesive layer at the corner of single-lap joints was calculated from the failure load. A substantial improvement in the failure load and stress intensity factor of epoxy/nano-Al 2 O 3 adhesives was obtained compared to the base adhesive. The maximum failure load and stress intensity factor of epoxy/nano-Al 2 O 3 adhesives were found at 1.0 wt% of Al 2 O 3 nanorods and 1.5 wt% of Al 2 O 3 nanospheres. The failure load and stress intensity factor of epoxy/nano-Al 2 O 3 a...

纳米Al 2 O 3增强环氧胶粘接单搭接钢接头的破坏载荷和应力强度因子。

实验分析了环氧/纳米Al 2 O 3胶粘剂对单搭接钢接头的破坏载荷（受拉力的影响）。重量百分比分别为0.5％，1.0％，1.5％的球形纳米Al- 2 O 3和直径<10 nm且长度<50 nm的棒状纳米Al 2 O 3和2.0 wt％）。由失效载荷计算出单搭接缝拐角处胶粘层的应力强度因子。与基础胶粘剂相比，环氧/纳米Al 2 O 3胶粘剂的破坏载荷和应力强度因子得到了显着改善。发现环氧/纳米Al 2 O 3粘合剂的最大破坏载荷和应力强度因子为1.0 wt％的Al 2 O 3纳米棒和1.5 wt％的Al 2 O 3纳米球。环氧/纳米Al 2 O 3 a ...的破坏载荷和应力强度因子
