One such composite material is the Glass/Epoxy which is considered in this research work. The kerf taper angle which is an important cutting performance measure of the abrasive water jet machined composites were calculated. The Grey based Taguchi method was adopted in order to find the significance the input parameters. The standoff distance, traverse rate were found to be the most significant parameters as it had the highest grey relational coefficient. This study is based on single response experimentation (kerf taper angle). The kerf taper angle is an undesirable inherent phenomenon in abrasive water jet machining. Polymer matrix composites are being widely used in various industries due to their superior properties. The abrasive water jet machining proves to be a better cutting technology for such difficult to machine materials because it produces numerous advantageous characteristics like self cleaning, low thermal stress induces etc. Since these underlying characteristics are very much required when considered at an industrial scale, the abrasive water jet machining has attracted the attention of the manufacturing industry over the other unconventional machining processes. Even though AWJM presents these characteristics, the kerf taper remains to be unavoidable and undesired. A literature study shows that the AWJ cutting can produce good quality kerf if the cutting parameters are properly optimized. The traverse rate and the standoff distance were found to have a profound effect on the kerf width. This work focuses on minimizing the kerf taper angle by selecting the optimum machining parameters (pressure, standoff distance and traverse rate) through an experimental design and the significance of parameters is obtained by using Grey Taguchi method.

Because of the expanding natural concerns, bio composite produced out of regular fiber and polymeric resin is one of the latest advancements in the business and constitutes the present extent of experimental work. The use of composite materials field is increasing gradually in engineering. The composite consists of mainly two phases i.e. matrix and fiber. The accessibility of characteristic fiber and simplicity of assembling have enticed scientists worldwide to attempt by regional standards accessible inexpensive fiber and to learn their achievability of fortification determinations and to what degree they fulfill the obliged of great strengthened polymer composite aimed at structural requisition. Fiber reinforced polymer composites has numerous preferences, for example a minimal effort for creation, better quality contrast than perfect polymer tars. Due to these reasons, fiber strengthened polymer composite utilized within an assortment of provision as class of structural material. This work describes the mechanical behavior of banana fiber reinforced polymer composite with extraordinary references to the impact of fiber loading and the length of fiber on the properties of composite in mat form.
