Investigations for improving solid-state weldability of dissimilar thermoplastic composites through melt processing

Abstract

This study deals with melt processing of Al electrolytic particle reinforcement in thermoplastic matrix (for enhancement of weldability of dissimilar thermoplastics). Further, the melt flow compatible substrates of Al-reinforced thermoplastic matrix were 3D printed, followed by joining on vertical milling machine. The study also deals with mechanical properties evaluation with traverse force monitoring for input process variables selection. The outcome of study suggested that maximum mechanical strength was obtained at 1400 rpm, transverse speed 30 mm/min, and plunge depth 4 mm. The study is supported by 3D surface topology and optical micrographs.
