Fabrication, Characterization and Drilling Operation of Natural Fiber Reinforced Hybrid Composite With Filler (Fly-Ash/Graphene)

Abstract

The aim of the work is to investigate mechanical properties and machining (drilling) behaviour glass-sisal-epoxy hybrid composite (GSEHC) with filler as fly-ash and graphene. Hybrid composites are fabricated by hand lay-up technique using Eglass and sisal as reinforcement fiber and epoxy as binder. Mechanical and physical properties like tensile, bending, impact strength, hardness, density and water absorption percentage are examined. The interfacial properties, internal cracks and internal structure of fractured are observed using Scanning Electron Microscope (SEM). Further drilling operation on the fabricated Hybrid composite was carried by varying the spindle speed as 600 rpm, 900 rpm, 1200 rpm to observe suitable drilling speed to carry the circularity test and delamination factors.
