Investigations On Drilling Characteristics Of Glass-Bamboo Reinforced Hybrid Composites

Abstract

Polymer matrix composites possess better properties like great strength-to-weight ratio, stiffness-to-weight ratio, and noble corrosive resistance and consequently, are chosen for high-performance applications like in the aerospace, defense, and sport goods industries. Drilling is one of the vital methods for structure products with composite panels. By adjusting the cutting speed, feed rate, and tool geometry, this work aims to highlight the machining properties of the hybrid composites. The hand lay-up approach was used to create the hybrid composite specimens. Using MATLAB's image analysis technique, the damage caused by drilling is investigated. Regression analysis and ANOVA are used to analyze the data in order to reach the ideal condition. For drilling hybrid composites, it was found that the center drill, higher spindle speed (5500 rpm), and lower feed value (0.18 mm/rev) provide the least amount of delamination. For thrust force, it was discovered that the feed rate mattered more than the spindle speed and drill geometry
