Abstract

In the process of continuous improvement of manufacturing processes in the field of the automotive sector comes this study developed within the framework of the Ecovoss project. Its objective is based on substitution of aluminum welding operations with the option of adhesive operations with other types of materials such as polyamides or, in this case, a TEPEX® composite material (dynalite 202-c200 / 50% TYP 13). In this work we try to test the best texturing in the union of 7075 aluminum specimens manufactured by robotized polishing with ABB 6640 robot, with specimens in TEPEX® material cutted in order to have a surface for application of the adhesive product. It uses a structural adhesive film AF-163-2 from 3M, which must be applied with determined pressure and temperature. The tests carried out are based on the topographic measurement of the surfaces to be adhesively bonded with the Alicona interferometer and in the tests for cutting the adhesive bond. The expected results must provide the state conditions of the surfaces to optimize the adhesiveness of the materials studied.
