Open Hole Tensile Test for Measuring Residual Tensile Strength and Delamination of Glass Fibre Metal Mesh Polymer Composites

Glass Fibre Metal Mesh Polymer Composites (GFMMPC) are one of the alternative for engineering materials because their elevated mechanical properties. This work focuses on tensile test with open hole which is based on optimization of parameters. For the drilling experiment, Taguchi L8 two level orthogonal array a strategy was used to examine each parameter’s influence and systematically evaluate the experimental parameters. Spindle speed, feed rate, and condition (dry and wet) with two levels are some of the drilling parameters that were chosen. Eight drilling tests were carried out, each in a different order. After the drilling trials are finished, hole properties are observed using Scanning Electron Microscope (SEM) this was done to assess the degree to which drilled holes are delaminated. The Corel draw was used for measuring the delamination factor. Also residual tensile properties measured using tensile test. Based on responses the optimized parameters are higher for high spindle speed (4000 rpm) and low feed rate (50 mm/min). Morphological study of the fractured samples are analysed using SEM.
