Abstract
For practical applicability of friction stir welding (FSW) in repair/assembly of thermoplastics, it is required to have compatibility between two dissimilar polymers (from mechanical, morphological, chemical, and thermal view point). This study highlights that reinforcement of 15% Al powder in ABS (as ABS-15Al) and 50% to PA6 (as PA6-50Al) resulted in similar melt flow index (MFI) range of 11.57 g/10 min and 11.97 g/10, which further confirmed the enhanced material compatibility with possibility of FSW. The processing of polymer composite on twin-screw extrusion (TSE) process followed by substrate preparation on fused deposition modeling (FDM) as digital manufacturing tool has been used in the present study (to prepare functional prototypes for FSW on milling setup). The output parameters such as grain size number on stirred zone, break load, break strength, and Young’s modulus of welded joints have been investigated.
