Performance Study on Drilling of Glass Fibre Reinforced Polymer Nano Composites and Their Mechanical Behaviour

Abstract

Fibre-reinforced polymer nanocomposites (FRPNCs) have recently been playing a significant newlinerole in a various engineering fields and are extensively used in numerous engineering domains newlinelike functional and structural applications because of their superior engineering qualities. The newlineincorporation of nanoparticles reinforcement into the epoxy resin enhances the mechanical, newlinethermal and electrical characteristics of FRP nanocomposite laminates. Nano-fillers improve the newlinerequired qualities in composite laminates with a very minimal amount of doping material, in newlinecontrast to micro and macro reinforcing compounds. The glass fibre reinforced polymer newlinenanocomposites are heterogeneous and anisotropic (fibre as well as intra-layer anisotropy), newlinelacking plastic deformation and challenging to machine. Conventional machining methods often newlinelead to structural and health concerns, including reduced tool life, delamination, matrix newlinedebonding, smearing, fibre pull-out, heat degradation and the generation of unhealthy dust. The newlinedefects significantly impair the performance and durability of the composite components. newlineMultiple aspects, including tool geometry, thrust forces, and machining variables, can influence newlinethe quality of a machined hole. Regardless of their intended production, hole drilling is newlinefrequently essential for the assembling and joining of intricate components. In composite newlinematerials, damage-free holes are essential for attaining superior joint strengths and optimal newlinefatigue life. newlineIn manufacturing industries, drilling is an unavoidable machining process frequently used to newlinecreate holes for assembling various parts in laminated structures, ensuring the structural integrity newlineof intricate composite products. This is particularly important in aeronautical constructions, newlinewhere a single commercial aircraft may require numerous drilled holes. In the aerospace newlineindustry, a significant percentage of rejection rates are attributed to drilling-induced newlinedelamination, which can be costly concerning both time and money. Therefore, during the newlinedri
