Secondary Processing of Reinforced Polymer Composites by Conventional and Nonconventional Manufacturing Processes

Machinability investigation in electric discharge machining of carbon fiber reinforced composites for aerospace applications

“…[1][2][3][4] Due to their extreme hardness, toughness, as well as their anisotropic nature, CNT/CF is considered difficult to cut materials by using conventional machining methods because these result in high tool wear, delamination, and fiber pull-out. [3,5,6] The failures arising from the machining of these materials were found to reduce the strength and fatigue life of the components. The electric discharge machining (EDM) is one of the non-conventional machining techniques which involves the melting and evacuation of debris from the electrically conductive workpiece.…”
