混杂聚合物复合材料由于其上级特性而被广泛应用。由于纤维分层和表面损伤，这些材料中的常规切割技术产生差质量的加工。通过常规机械加工在聚合物复合材料中产生形状和切口也具有挑战性。磨料水射流加工（AWJM）可以通过控制加工过程来产生高质量的切割。本文研究了赤泥填充剑麻/聚酯混杂复合材料的加捻变形。通过实验数据建立了材料去除率（MRR）和切口锥度（KT）的二阶回归模型。所建立的模型在95%的置信水平下以最小误差预测MRR和KT。混杂复合材料的MRR受横向速度的影响最大（83.56%），而KT受射距的影响最大（SOD，45.66%）。通过对切割面的扫描电镜分析，了解了磨料磨具的破坏机理。
Hybrid polymer composites have been used in various applications because of their superior characteristics. Conventional cutting techniques in these materials produce poor quality machining because of fiber delamination and surface damage. It is also challenging to produce shapes and cuts in polymer composite materials through conventional machining. Abrasive water jet machining (AWJM) may be suitable for producing quality cuts by controlled machining process. This article investigated the AWJM of red mud–filled sisal polyester hybrid composite. The second order regression model was developed for material removal rate (MRR) and kerf taper (KT) through the experimental data. The developed model predicted the MRR and KT with minimum error at 95 % confidence level. The MRR of the hybrid composite was influenced highly by transverse speed (83.56 %) whereas the KT was influenced mostly by standoff distance (SOD, 45.66 %). Scanning electron microscope (SEM) analysis on the cut surface helps to understand the failure mechanism on AWJM.
