ABSTRACT

One of the biggest research discipline todays is the weight reduction of the vehicles. The manufacturers are focusing on making new hybrid materials and innovative technologies that satisfy the newest requirements, such as light weighting. There exist many solutions to reach lower vehicle weight, reduce the air pollution and CO2 emission. One of them is the hybrid materials pairing in the different part of the vehicle body. These joining technologies have to complete the new requirements for hybrid joints for this the weakest part of the bonding have to increased. The strength of the adhesive joining can be increased with different surface preparation methods. In this research five different surface treatment were investigated to increase the tensile stress of the overlapped Glass Fiber Reinforced Plastic and Aluminum sheets. The macro geometry of the connecting materials, the tension stress and the breaking method were investigated during the analysis. The research investigates the connection between the surface properties and the adhesive technology using hybrid materials connection.
