Fabrication & erosion wear response of E-glass-epoxy based hybrid composites filled with CFA/CFACP

Abstract

In this research work Coal Fly Ash (CFA)/ mixture of Coal Fly Ash (CFA) and Coal Powder (CP) filled E-glass Fiber Epoxy Resin Hybrid composites were fabricated with three weight proportions (0wt%, 5wt% and 10wt %) by manual hand layup technique. Coal Fly Ash and Coal Powder are the solid waste generated from power generation plants (VTPS, VJA). The erosion wear behavior of the composites were determined at different impingement velocities (30, 60 and 90m/sec), impingement angles (45°,60° and 75°), weight proportions (0%, 5%, 10wt %) and S.O.D (25, 35 and 45mm) at constant feed rate of Al 2 O 3 of 5grams/min and size of (50 m) following the experiments of erosion by Air Jet erosion Test Rig. It was observed that with the addition of fillers (CFA/CFACP) to E-Glass Fiber Epoxy composites. Hardness and erosion wear resistance were improved and the effect/influence of control factors (Impact velocity, Impingement angle, S.O.D and weight percentage of fillers) on erosion wear rate were determined by ANOVA.
