Abstract

The delamination at hole entrance surface has a significant impact on the strength and stiffness property of material on delamination factor calculation methods used by Chenand Davim. Delamination frequently happens around the holes in drilling even though interlaminar strength is good. In this study, the drilling of functionalised amine based multi-wall carbon nano tubes (MWCNTs) carbon fiber laminate composite was examined for hole quality by three different point angles as one major parameter. Numerous drilling operations need to perform for assembly of carbon-fiber-reinforced-plastic (CFRP) in aircraft parts. Drilling carried out with Design-of-Experiment (DOE) from Taguchi based on the feeding rate, cutting parameter, and point angle as L27 Orthogonal array. The impact of machining quality on stiffness degradation was further examined by NDT (Non-Destructive Testing) i.e., infrared thermography and digital microscope in which cutting speed 1000 rpm, feed rate 20 mm/sand point angle 118º interpreted the values as minimum delamination in both the NDT observations and are plotted the same using Python programming.
