Abstract

The natural fiber reinforced polymers have been successfully used in applications such as automobiles, constructions, infrastructure and other Industries because of its low cost, acceptable strength and stiffness, low weight and ease of degradable. The thermal, dimensional stability and machinability behaviours are generally studied in order to propose the application of composites. The thermal characteristics such as weight loss due to temperature and phase transition were studies for sisal-epoxy composites in the present investigation. The water, oil and chemical absorption characteristics were studied for coated and coated fiber reinforcements in composites. Drilling is a metal removal process and is important for the application of products during assembly. The present investigation is focused on the study of influence of drilling parameters such as spindle speed, feed rate on drilling characteristics such as thrust force, torque and delamination factor on uncoated and coated sisal fiber reinforced epoxy composites. The HSS twist drills were used and drilling test was carried out using MAXMILL CNC drilling machine. From the experimental observations, the drilling characteristics for various drill bits for the uncoated and coated sisal-epoxy composites were listed.
