Sathishkumar Assistant Professor Department of Mechanical Engineering RVS College of Engineering and Technology, Coimbatore – 641402 Abstract The objective of this paper is to compare and analyse the effect of inclusion of Glass fibre and Basalt fibre on the Vinyl ester and Vetiver fibre composite during machining process. The machining process selected is drilling operation because it carried out in most of the assembling process. The thermal loadings were done for all the compositions that are chosen and The analysis will predict the better performance among the two composites with varying proportion on ANSYS14.5 (WORKBENCH). The analysis shows the basalt fiber reinforced hybrid composite show the low heat flux and smooth temperature distribution than the glass fiber reinforced hybrid composite.

INTRODUCTION Now-a-days, the use of Glass fibre reinforced composites has increased in various areas of science and technology due to its special property. The wide range of application in Aircraft industries. On Aircraft’s for Assembling two structures accomplish machining process. The mechanical drilling is used as generally for application mainly, 1) To Create hole, 2) To enlarge hole, As drill is rotated and advanced into a work piece a material is removed in the form of chips that move along the fluted shank of the disk. Fibre Reinforced hybrid Composite Consists of two or more fibres which are reinforced along with the resin system. So, the properties of the resulting composite material will combine something of the properties of resin on its own with that of fibre on their own. Overall, the property of their composite depends mainly on 1) Property of fibre 2) Property of composite 3) Fibre Volume fraction (ratio of fibre to resign) II. MATERIALS FOR ANALYSIS Glass Fibre: A. Generally, the Glass fibres were used in manufacturing of air craft structures, but they were very costly and non-biodegradable. Their composition includes S-Glass has a typical nominal composition of SiO 2 65wt%, MgO 10st%. Some other materials may also be present a impurity levels. Table 1: Properties of Glass fibre.
