Background
The shear strength is the maximum breaking load per unit area of the adhesive when it receives a stress in the tangential direction, and the conventional test principle is to apply a longitudinal tensile shear force to the faying surface of a sample and measure the maximum load to which the sample is subjected, and the average shear stress on the faying surface is the tensile shear strength of the adhesive faying. The two test materials in the adhesive shear test comprise an adhesive and a bonded material, wherein the adhesive is bonded with different bonded materials, the bonding performances of the adhesive and the bonded materials are different, and the bonding strengths of the adhesive and the bonded materials are different. Therefore, even if the same adhesive is tested, different materials to be bonded need to be replaced. In addition, the effect on shear strength when subjected to different lateral stresses is also taken into account when testing. In addition, in the sample testing process, multiple tests need to be performed, and the average value of the tests is taken, so that the test result is more accurate as the number of times is more, but the load, time and cost of the test are also increased. There is therefore a need for a clamp that can quickly replace a sample, both when replacing the material being bonded, and also can apply lateral forces to the sample and quickly perform multiple test tests.
