In this paper, the feasibility of Direct-Friction Riveting is demonstrated for Ti6Al4V rivet and carbon-fiber reinforced polyether-ether-ketone laminate single lap joints. Due to high shear rates, elevated process temperatures (500–900 °C) and fast cooling rates (38 ± 2 °C/s) experienced by the rivet tip, α′-martensitic structures were identified in the rivet anchoring zone along with fiber and polymer entrapment at the rivet-composite interface. An average ultimate lap shear force of 7.4 ± 0.6 kN similar to conventional lock-bolted single lap joints was achieved. These results indicate that Direct-Friction Riveting is a competitive method with potential for improvement and further application in aircraft structures.en1873-4979Materials letters20183134Direct-Friction RivetingTi6Al4VWoven carbon-fiber reinforced compositesTechnology::600: TechnologyDirect-Friction Riveting of polymer composite laminates for aircraft applicationsJournal Article10.1016/j.matlet.2017.12.033Journal Article
