Kenaf Fiber is one of natural fibers which becoming popular as a reinforced for plastic composite material in the industrial application such as aircraft, automotive, sporting goods, and marine engineering. In machined kenaf fiber composite, the important factor should be control is the delamination factor in order to control the quality of product. The delamination of a milled kenaf reinforced plastic is depending on the milling parameters (spindle speed, feed rate and depth of cut). Therefore, a study was carried out to investigate the relationship between the milling parameters and their effects on a kenaf reinforced plastic. In this study, the composite panels were fabricated using vacuum assisted resin transfer molding (VARTM) method. A full factorial design of experiments was used as an initial step to screen the significance of the parameters on the defects using Analysis of Variance (ANOVA). If the curvature of the collected data shows significant, Response Surface Methodology (RSM) is then applied for obtaining a quadratic modeling equation which has more reliable in expressing the optimization. Thus, the objective of this research is obtaining an optimum setting of milling parameters and modeling equations to minimize delamination factor of milled kenaf fiber reinforced plastic composite. The spindle speed and feed rate contributed the most in affecting the delamination factor of kenaf fiber composite.
