Process Transferability of Friction Riveting of AA2024-T351/Polyetherimide (PEI) Joints Using Hand-Driven, Low-Cost Drilling Equipment

The present work deals with the transferability of Friction Riveting joining technology from laboratory equipment to adapted in-house, low-cost machinery. A G13 drilling machine was modified for requirements selected technique, and joints were performed using polyethermide plates AA2024 aluminum alloy rivets 6 mm diameter. This diameter not previously reported Riveting. produced mechanically tested under tensile loading (pullout tests) ultimate forces 9500 ± 900 N. All specimens failed through full-rivet pullout, which is weakest joint in In order understand this behavior, FE models created analyzed. agreement experimental results, failure initiated within polymer stress concentrations polymeric material above deformed metallic anchor at an value 878 MPa surface joint. Stresses decreased less than half maximum around anchoring zone while rivet removed towards surface. paper thus demonstrates potential ease applying reproducing simple machinery, contributing understanding mechanical behavior (initialization failure) joints.
