A proposal for a new method of testing the impact strength of adhesive joints
The usefulness of the proprietary method of testing the impact strength of adhesive joints under shear loads was checked. An adhesively bonded lap sample of flat bars with a thickness of 5 mm, loaded on the side surface of the overlap, was proposed. Numerical calculations have shown that in such a l...

| description | The usefulness of the proprietary method of testing the impact strength of adhesive joints under shear loads was checked. An adhesively bonded lap sample of flat bars with a thickness of 5 mm, loaded on the side surface of the overlap, was proposed. Numerical calculations have shown that in such a loaded lap joint, shear stresses dominate. Impact tests of such specimens can be performed on conventional Charpy hammers. Experimental tests were carried out on samples made of steel, brass and aluminum alloy bonded with various adhesives: Epidian57/Z1, Raychem S1125, Loctite 9464 and DP 420. The conducted experimental tests showed high reproducibility of the results of such tests and as expected, higher destruction energy of flexible adhesive and adhesive layers of greater thickness was obtained. |
