Abstract

Glass fiber reinforced plastic (GFRP) composite materials are continuously replacing the traditional engineering materials and are finding increased applications in many fields, such as automobile, marine, sport goods etc,. Machining of these materials is needed to achieve near-net shape. In machining of composite materials, optimization of process parameters is an important concern. This paper presents, the use of Fuzzy logic combined with Taguchi method for the optimization of multiple performance characteristics considering surface roughness, cutting force, specific cutting pressure and cutting power. Experiments were planned using Taguchi's L₂₅ orthogonal array with the cutting conditions prefixed. The process parameters considered are workpiece (fiber orientation), cutting speed, feed, and depth of cut. The machining tests were performed on a lathe using carbide (K20) cutting tool. The results indicated that the optimization technique is greatly helpful in optimizing the multiple performance characteristics simultaneously in machining of GFRP composites.

Abstract

A composite is usually made up of at least two materials out of which one is binding material called as matrix and other is a reinforcement material known as fiber or whisker. The important characteristics of composites are their strength, hardness rigid light in weight. Composites can be produced by using natural fibers such as banana fiber, bamboo fiber, jute, coir and silk. Bamboo posses better properties than other natural fibers. In the present work, composites are produced from epoxy resin with bamboo fibers. The bamboo fibers of 3mm in diameter (approximately) of fixed percentage (08% by weight fraction) are placed in different orientation i.e.30°, 45°, 60°, and 90°. The mechanical properties such as tensile strength, flexural strength, and impact strength tests are conducted.
