摘要：

The application of structural adhesives is increasing as a method of fixation in the various segments of industry, especially in the automotive industry. This is justified by the need to reduce energy consumption and save resources, thus bringing a series of benefits to the product / process compared to traditional fastening systems with bolt, rivet or weld. This study studied some factors that influence the mechanical strength of the adhesive shear tests submitted to the Lap Shear and Cross Peel tests. Three different adhesive thicknesses were used to make the adhesive joints (0.80, 1.50 and 3.00mm). In addition, it was possible to identify the effect of different base materials on the mechanical behavior of the adhesive joints. Experimental results have shown that minor adhesive thicknesses considerably increase the mechanical strength of the joints subjected to shear traction tests. On the other hand, the results of the cross-traction test did not obtain this same behavior. However, there is a relationship between the performance of the joint and the material of the substrate to be bonded.
