The automotiveindustry is one of the most dynamic, advanced and innovative industries in Europe, being in constant search of solutions to reduce fuel consumption and pollutant emissions while maintaining or even improving the safety of passengers. One of the main directions in which the research of all car manufacturers is focused to reduce the weight of the car, through the increasing use of light metal alloys and polymeric materials. Polyethylene is one of the most widely used polymeric materials in the world, being widespread in many industries.The increasing use of this category of materials has led to the need to develop new reliable and efficient techniques for joining different materials to be used in complex structures. In the aeronautical and aerospace field, polymeric materials are used due to their low weight. The paper presents the macroscopic and microscopic analysis of the joining of these materials by FSW.
