Effect of the friction riveting process parameters on the joint formation and performance of Ti alloy/short-fibre reinforced polyether ether ketone joints

摘要: Abstract The feasibility of friction riveting on short carbon fibre-reinforced thermoplastic polymers was investigated in this work. A design experiments (DoE) used to investigate the impact rotational speed, time, pressure and forging joint formation performance. studied using mushrooming efficiency, rivet penetration depth mechanical energy input. tensile pull-out force describe performance metallic-insert joints made grade 3 titanium polyether ether ketone (PEEK). All samples were scanned with X-rays before any testing acquire dimensions anchored inside reinforced polymer, elucidating their correlations DoE model can be tailor parameter-set that improves determined an analysis variance. revealed high time caused forces. reached strength between 6.3 kN 10.7 kN. deformed metallic correlated joint: larger widening tip, higher pull out was. Furthermore, tip by 70% led maximal (10.7 kN), corresponding base material (10.7 kN). At threshold value (70%), failure mode also changed from III (pull-out rivet) I (rivet failure).
