Abstract
An investigation was performed to study the mechanisms of abrasive waterjet cutting of unidirectional carbon/epoxy composite rods. The objective of the study was to determine the feasibility of using abrasive waterjet cutting to machine high quality, standard dimension screw threads. Experimental trials were performed to identify suitable cutting conditions for machining threads in unidirectional, carbon/epoxy rods. Parameters including traverse speed, crossfeed and nozzle / orifice dimensions were varied and conditions providing high quality screw threads were determined. Scanning electron microscope (SEM) examinations of the machined threads revealed different surface characteristics at different locations along the thread profile. Evidence of several composite failure mechanisms, including fiber-matrix interface failure, fiber pullout and fiber failure, was observed. It is concluded that through careful control of the abrasive waterjet machining parameters, high quality screw threads can be obtained.
