Abstract
Carbon fibre reinforced polymer (CFRP) composites are among the most widely used composite materials in the aerospace industry, thanks to the high specific mechanical properties offered. These composites combine the fundamental aeronautical requirements of lightness and strength, which have sparked great research interest in improving the properties and the production process of composite materials. CFRP composites can be manufactured in near net shape; however, they often require further machining processes such as drilling, particularly for joining purposes. Fibre orientation plays a fundamental role in CFRP composite materials, affecting the mechanism of chip formation and the quality of the cut surface and making machining of CFRP a challenging task. Proper optimisation of the drilling process can substantially improve CFRP parts quality, which may be affected by several faults generated during the process. In order to simplify the assembly operations and reduce manufacturing costs, efforts are increasingly spent with the aim to optimise CFRP drilling.
