| Abstract Scope |
Superwood is a lightweight, renewable structural material being investigated as a substitute for metallic alloys in automotive applications. To be more readily adapted into existing automotive manufacturing facilities, the new material was tested for compatibility with industry standard joining processes. This paper will examine joining of superwood to aluminum 5754 via self-pierce riveting and rivbonding. Both finite element modelling of the SPR process and lab testing of joints were used to determine joining practices suitable for superwood with a focus on the effect of rivet geometry and insertion speed on the prevention of cracking in superwood during rivet insertion and optimizing the quality and strength of joints in lap-shear. The joints created are stronger than wood-wood joints and showing the same joint quality as wood-Al. |
