Investigation the effect of electroplating and filler material on the tensile properties of wollastonite reinforced ABS composites

This paper deals with effects of wt. % of wollastonite (CaSiO₃) filler in acrylonitrile-butadiene-styrene (ABS) polymers prepared by injection moulding process and electroplating on the specimens. The influence of filler was examined by the different wt. % (3, 5 and 7) of wollastonite (CaSiO₃) in ABS. Filler was mixed with ABS polymer by twin screw extrusion process and pelletized. The composite pellets are used for the injection moulding process and specimens are prepared as per ASTM. The specimens are coated with nickel, copper and chromium with a thickness of 0.8 microns each by electroplating technique. The dispersion of fillers are studied by SEM. The improvements in tensile properties of 5 wt. % of filler in ABS and same wt. % of filler with electroplating components were 66% and 87 % respectively when compared with pure ABS.
