Abstract

One of the machining failures in composite materials is delamination damage. In this paper, machining parameters and delamination damage caused by the drilling process on ramie woven reinforced composite material with an unsaturated polyester matrix were investigated. The ramie woven used is ramie yarn type 12S/3. The machining process used 1.5 kW Pillar drills, where variations in the diameter of the "brad & spur" drill are 4 mm, 6 mm, 8 mm, and 10 mm, respectively. In this work, focuses on the influence of machining parameters like feeds rate and spindle speed. Holes quality was analyzed in terms of thrust force and delamination failure. From the results of this study, the thrust force value obtained at the time of drilling is very closely related to the delamination damage that happens. Delamination damage occurs on both sides of the holes drill.
