Abstract
The impact strength of an acrylic adhesive under high temperature was tested when impact tensile load was applied to tubular butt joints. The material of the adherend was aluminium alloy A5052-H34 and acrylic adhesive Hardloc M-372-20 was used. In the impact tensile test under high temperature, the thickness was fixed at 0.1mm. Main results are as follows: At the room temperature, the impact strength of the adhesive was higher than the staticone. The impact strength decreased with increasing the temperature, where in the adhesive layer maintained its shape for along time within 150℃ and for a short time with in 250 oC, respectively.
