ABSTRACT

With steadily rising expanse of the engineering sector, demand for composite materials has been growing progressively over the years. Particularly, glass fiber reinforced polymer (GFRP) composites are being increasingly applied in various industries in the aerospace, automobile, and construction sectors due to their lightweight and superior performances. The present investigation examines the effect of traverse rate, jet pressure, standoff distance, and multi-walled carbon nanotubes (MWCNT), mixed with epoxy/glass fabric nanocomposites, on abrasive water jet machining (AWJM) responses, such as kerf taper (KT), surface roughness (R_a), material removal rate (MRR), entrance and exit delamination factor (DF) by using the Taguchi approach. The study has established that the addition of MWCNT in the GFRP laminates optimizes the machining responses. The investigation, using analysis of variance approach, revealed the most dominant parameter, which influences the machining performance of the composites. A significant enhancement in AWJM responses could be attained with optimal parameters. And also validates using surface examinations.

摘要

随着工程领域的稳步扩大，对复合材料的需求多年来一直在逐步增长。特别是，玻璃纤维增​​强聚合物（GFRP）复合材料由于其轻质和优异的性能，越来越多地应用于航空航天、汽车和建筑领域的各个行业。本研究考察了横向速率、射流压力、间隔距离和多壁碳纳米管 (MWCNT) 与环氧树脂/玻璃织物纳米复合材料混合对磨料水射流加工 (AWJM) 响应的影响，例如切口锥度 (KT) ), 表面粗糙度 (R _a)、材料去除率 (MRR)、入口和出口分层因子 (DF) 使用田口方法。研究表明，在 GFRP 层压板中添加 MWCNT 可以优化加工响应。该调查采用方差分析方法，揭示了影响复合材料加工性能的最主要参数。使用最佳参数可以显着增强 AWJM 响应。并且还使用表面检查进行验证。
