A Digital Image Analysis to Evaluate Delamination Factor after Drilling GFRP Composites using a Kevlar Drill Bit
Objectives: Evaluation of three important delamination factor models and compare their values with varying spindle speeds and feed rates in drilling GFRP composites. Methods: Digital image analysis is adopted for measurement of the dimensions of delamination damage. Accurate assessment of delamination damage is essential for the analysis and design of optimum drilling parameters. Experiments were conducted on GFRP composite materials with feed rates ranging from 100-400 mm/min and spindle speeds ranging from 1000-2500 rpm. Findings: These experiments reveal that delamination reduces with increase in the spindle speed and reduction in the feed rate, but higher spindle speeds may increase the delamination damage. Results also reveal the consideration of area of delamination damage in the assessment of delamination is more important than the maximum damage diameter. Applications: The good mechanical properties of GFRP composites allow their use in compartment panels and doors. Digital image analysis improves the accuracy in measurement of delamination damage.
