Optimization of abrasive water jet machining parameters for basalt fiber/SiO2 nanofiller reinforced composites
Original language description
To minimize machining-induced delamination and surface roughness during abrasive water jet machining (AWJM) of basalt-fiber/silica dioxide (SiO2)-nanofiller epoxy laminates and to define process windows for high-quality holes/slots. Laminates were fabricated from basalt fiber mats (0 degrees/90 degrees) in an epoxy matrix containing 2-8 wt% SiO2 nanoparticles. AWJM trials systematically varied cutting speed, abrasive flow rate, and stand-off distance (SOD), with jet pressure examined to interpret damage mechanisms. Responses included entry/exit delamination factor (image-based, equivalent-diameter metric) and surface roughness (R a), complemented by scanning electron microscopy (SEM) of cut edges. A response surface methodology (RSM) with multi-response desirability optimization was used to develop predictive models and identify optimal settings. Lower cutting speeds, moderate abrasive flow, and higher SOD consistently reduced delamination and improved surface finish; SEM revealed that higher jet pressure suppressed matrix washout and fiber pull-out, whereas low pressure increased surface defects. The RSM models showed strong predictive agreement with validation experiments, enabling contour maps and trade-off curves for concurrent delamination-roughness control. The study provides experimentally validated guidelines for precise parameter control in AWJM of basalt/SiO2 laminates, supporting low-damage, assembly-grade machining of composite components. The resulting process windows are directly applicable to aerospace (e.g., brackets, panels, fittings), automotive (lightweight structures), and construction where surface integrity and structural reliability are critical.
