Optimization of multi parameters of WEDM using ANN based on principal component analysis for AA6063/B4C metal matrix composites

Abstract

Improved mechanical characteristics for composites using a linear low-density propylene (PP) matrix and a carbon fibre (CF) filler were the focus of this study. The material was fabricated by a hand layup process in an oven. Oxygen plasma treatment of the PP matrix enhanced adherence. Before being filtered and dried for manufacture, CF and PP were first combined with standard stirring, ultrasonication, and mechanical stirring. The highest tensile strength was achieved in plasma-treated propylene (PPP) with 10 wt% CF, with overall property performance increasing by 13.46 % comparison to non-PP with the same CF addition. Tensile strength was reduced from 19.4 MPa to 18.3 MPa when carbon fibers were added at 14 and 16 wt%. As a result of CF aggregation with plasma-treated and untreated PP, tensile strength (TS) was reduced. Better tensile qualities were seen in a factory setting with temperatures of 180 °C for 20 min. After plasma treatment, the PP/8% CF blend had a flexural strength (FS) of 26.19 MPa, which was higher than that of untreated PP by a significant margin.
