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<br/>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.<br/>Different combinations of materials have been successfully joined, using metals such as aluminum, steel and titanium. Polymeric materials have been joined in unreinforced and<br/>reinforced configurations, of both thermoplastics and thermosets. The process-controlling method here systematically investigated is force-control. Response surface methodology and<br/>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<br/>polyetherimide. Several process responses have been studied, such as the plastic deformation of the rivet, mechanical performance and energy input during the process. These<br/>investigations aimed for a deep understanding of the force-controlled process.
