Abstract
In this master thesis, a new method for SL joints improvement is proposed. It has been carried out a study of the behaviour of the SL adhesive joints when the surface of the adherends is modified by placing a certain geometry on them. Moreover, it has been studied the possibility of benefiting from the additive manufacturing processes in order to fabricate these geometries, since this technology provides limitless possibilities when it comes to geometry generation. Research on SL joint improvement reveals some studies that focus on the surface modification to improve the strength of the joint. These studies may be separated in two groups: those who propose a mechanical modification of the surface, and those who use additive layer manufacturing to assembly both components together.
In one hand, studies that propose mechanical modifications consist in a very simple geometry and does not let space for further improvements or modifications on them; since the geometries are performed through mechanical deformations of the current surface of the components, the geometries that may be generated are limited with few variations
