Joining Strength of Self-Piercing Riveted Vibration-Damping Steel and Dissimilar Materials

A vibration-damping steel panel is used for lightweight vehicles to block any noise subjected the passenger cabin replacing heavy fiber-based insulators. Conventional weld joining methods often encounter problems due presence of viscoelastic compounds reducing joint quality and making process unproductive. In this work, we present experimental results that show self-piercing riveting (SPR) can be produce high-quality joints between (i) commonly alloy (SPFC590DP), (ii) carbon-fiber-reinforced-plastic (CFRP) panels. Various die shapes are investigate resulting interlock width bottom thickness tensile shear load tests were performed evaluate strength. The possible all dye types configurations, in study, producing up 6.2 kN load. High-quality also with CFRP 4.0 kN, however, acceptable formed only when panels on top during severe cracking.
