Abstract
The goal of this study is to quantify the surface roughness of drilled holes in a novel sandwich composite made of pineapple fiber reinforced with aluminium wire mesh and compare their performance to that of Plain epoxy. Composite made from pineapple fiber. Group1 specimen is prepared by using Pineapple fiber reinforced and epoxy composite, whereas the Group 2 specimens additionally reinforced with Aluminium wire mesh. Sample size calculated was 20 per group total samples 40. ASTM D 4417 standard followed for the sample’s preparation and testing. The samples drilled in the CNC vertical milling centre and roughness measured and compared. Cut rate (in millimeters per revolution), RPM, and drill diameter (in millimeters). Results acquired in T-independents PSS-based statistical analysis was P = 0.000 (P < 0.050)and the observations are found statistically significant. The aluminium mesh reinforcement in the composite improved the surface roughness from 3.10 µm to 3.57 µm. In the scope of this investigation, the proposed novel AWMC increased the SR on drilled holes by 15.16%.
