【 摘 要 】

In order to reduce the weight of a vehicle the designers have to use different materials pairing. During the light building the vehicle needs to complete the mechanical and structural requirements, these quality properties are especially important in the competition racings. To fulfil the needs while minimize the weight hybrid material usage and bonding are used. One of the critical joining is the Carbon Fiber Reinforced Plastic (CFRP) and aluminium pairing. In this paper we investigated the adhesive joining technologies of these hybrid pairings using hybrid and high strength adhesive. Our goal is to optimize the hybrid bonding while different surface treatment methods are used on the aluminium substrate. The mechanical properties, the surface roughness and the breaking method were investigates using tensile test and macro geometry inspection. In the results the connection between the surface topography and the mechanical properties were analysed.
