The mechanical properties of synthetic glass and natural sisal fiber-reinforced polyester laminates were evaluated in this investigation. The drilling operations were performed in the fabricated synthetic and natural fiber composites using CNC milling machine with measuring set up. The effect of input parameters such as point angle, spindle speed and feed rate on the drilling responses namely delamination factor, temperature in the drilling zone and noise level during drilling were analyzed. A systematic fuzzy model was developed to predict the drilling responses for varying drilling conditions in glass-polyester and sisal-polyester composite laminates.

Abstract


The mechanical properties of synthetic glass and natural sisal fiber-reinforced polyester laminates were evaluated in this investigation. The drilling operations were performed in the fabricated synthetic and natural fiber composites using CNC milling machine with measuring set up. The effect of input parameters such as point angle, spindle speed and feed rate on the drilling responses namely delamination factor, temperature in the drilling zone and noise level during drilling were analyzed. A systematic fuzzy model was developed to predict the drilling responses for varying drilling conditions in glass-polyester and sisal-polyester composite laminates.
