Experimental Study on the Drilling Parameter Analysis of Banana Fiber Reinforced Vajram Mixed Phenolic Resin Composite Laminates

ABSTRACT

Drilling operation of fiber reinforced polymeric (FRP) composites is significantly dissimilar from conventional drilling operation of metals; hence, identification of optimum drilling process parameters for FRP composites has become mandatory. In this work, drilling parameter optimization for banana fiber reinforced Vajram mixed phenolic resin composite has been carried out using Taguchi method. Three drilling input parameters such as point angle, spindle speed, and feed rate were optimized for two output responses, namely, thrust force and torque. Two composite samples were fabricated with 5% NaOH-treated banana fiber at 30% fiber volume ratio; sample 1 with 100% phenolic resin and sample 2 with 80% Vajram + 20% phenolic resin. Signal-to-noise ratios for all the output responses were calculated, and other statistical analysis were carried out. Highly contributing factor for sample 1 thrust force was point angle with 64.34% contribution and for torque was feed rate with 28.43% contribution. Highly contributing factor for sample 2 thrust force and torque was point angle with 60.47% and 41.37%, respectively. The residuals are fall on near straight line which ensures the normal distribution of errors; hence, no abnormality was noted on any analysis.

摘要

纤维增强聚合物 (FRP) 复合材料的钻孔作业与金属的常规钻孔作业有很大不同, 因此, 必须确定FRP复合材料的最佳钻孔工艺参数. 在这项工作中, 使用田口方法对香蕉纤维增强金刚砂混合酚醛树脂复合材料的钻孔参数进行了优化. 针对推力和扭矩两种输出响应, 优化了三个钻孔输入参数, 如点角, 主轴转速和进给速度. 用5%NaOH处理的香蕉纤维以30%的纤维体积比制备了两种复合材料;样品1为100%酚醛树脂, 样品2为80%金刚+20%酚醛树脂. 计算所有输出响应的信噪比, 并进行其他统计分析. 样本1推力的主要影响因素是点角, 贡献率为64.34%, 扭矩的主要影响因素是进给率, 贡献率为28.43%. 样本2推力和扭矩的主要影响因素是点角, 分别为60.47%和41.37%. 残差落在近似直线上, 这确保了误差的正态分布, 因此在任何分析中均未发现异常.
