Abstract
Friction-based welding is one of the most cost-effective and dependable methods for joining thermoplastics. However, there has been minimal work that has demonstrated the procedure/methods/equipment for welding two distinct types of thermoplastics. There is, nevertheless, a significant possibility of connecting the various thermoplastic materials by matching their melt flow index (MFI). One way for modifying the MFI is to reinforce it with micro/nano sized fillers. Fused deposition modelling (FDM) is a fast prototyping technology that employs thermoplastic-based filament to print components. The current study focuses on connecting aluminium (Al) metal powder reinforced acrylonitrile butadiene styrene (ABS) and polyamide 6 (PA6) thermoplastic substrates (3D printed by FDM) utilising friction welding (FW) / friction stir welding (FSW) / friction stir spot welding (FSSW). It was observed that the PA6 with 50% Al fillers (PA6-50% Al) and ABS matrix with 15% Al fillers (ABS-15% Al) produced MFIs of 11.97g/10min and 11.57g/10min, respectively.
