Abstract:

Lap shear strength developed at -67 F, room temperature, and 260 F on FPS-0003-cleaned 2020 T6 Al alloy bonded with AF-31 adhesive was determined. Average lap shear strengths of 2024T3 clad aluminum bonded with AF-31 are 3780 psi at room temperature, 2460 psi at -67 F, and 2210 psi at 260 F. Except for one result at -67 F, the 2020T6 results are somewhat higher than those obtained with 2024 clad alloy. Since 2020T6 is a high-temperature-resistant alloy, it is of significance that lap shear results at 260 F are 15 above those obtained on 2024. Author
