Abstract

The present study aims to develop a novel hybrid polymer composite with reduced graphene oxide (rGO) as filler and optimize its Abrasive Water Jet Machining (AWJM) parameters for reduced kerf width. The influence of rGO addition on kerf width is analysed in detail along with Pump pressure (bar), Transverse speed (mm/min) and Standoff distance(mm). The experiments are designed based on Taguchi's orthogonal array techniques in which L27 is adopted for three input parameters at three levels. The influence of each factor is used to identify the significance of selected parameters over kerf width, and it was found that stand of distance has a major effect over kerf width irrespective of rGO %. The addition of rGO filler has a significant effect on kerf width, which decreases with the addition of rGO up to 0.2% and kerf width increases for further addition of rGO.

摘要

本研究旨在开发一种新型的混合聚合物复合材料，以还原氧化石墨烯（rGO）作为填料，并优化其磨料水射流加工（AWJM）参数，以减小切口宽度。详细分析了 rGO 添加剂对切口宽度的影响，同时分析了泵压（bar）、横向速度（mm/min）和间距（mm）。实验基于 Taguchi 的正交数组技术设计，其中采用 L27 设计了三个输入参数的三个水平。利用各因素的影响来确定所选参数对切口宽度的重要性，结果发现，无论 rGO 的百分比如何，间距对切口宽度的影响最大。rGO 填料的添加对切口宽度有显著影响，随着 rGO 的添加，切口宽度逐渐减小，当 rGO 添加量进一步增加时，切口宽度增加。
