Optimization of Drilling Parameters of Fabricated GFRP Composite using Taguchi Method

In present era, day by day new engineering materials are forthcoming but among all, the composites, especially epoxy polymer composites have important advantages because of its superior mechanical properties such as high strength to weight ratio, high wear resistance, corrosion resistance, electrical resistance, and etc. It can replace the traditional materials for manufacturing different components with required properties. The major applications of these composites are in electronic industry, automobile industry and aerospace industry. In this work, a glass fibre reinforced polymer (GFRP) composite is fabricated using epoxy polymer Araldite LY556 matrix reinforced with 12 layers of glass fibers and properties such as tensile strength and hardness are measured. Generally, drilling of GFRP composites is difficult unlike traditional materials due to anisotropic nature. Hence, authors made an attempt to carry out the experimental study on drilling of GFRP composites and optimize the parameters based on material removal rate and delamination damage using Taguchi method.
