Abstract

The Friction Riveting process was developed to perform multi-material point-on-plate hybrid connections. The basic configuration of the process consists on joining a featureless
metallic rivet with a single unreinforced polymeric plate (Figure 1). Different configurations can be performed, joining multiple overlapping layers of a single or multiple materials.
Different combinations of materials have been successfully joined, using metals such as aluminum, steel and titanium. Polymeric materials have been joined in unreinforced and
reinforced configurations, of both thermoplastics and thermosets. The process-controlling method here systematically investigated is force-control. Response surface methodology and
central composite design of experiments were used to define the joining parameter sets. The materials used for this investigation were aluminum 2024-T351 (rivet) and unreinforced
polyetherimide. Several process responses have been studied, such as the plastic deformation of the rivet, mechanical performance and energy input during the process. These
investigations aimed for a deep understanding of the force-controlled process.
