Laser cutting has significant potential as a method of cutting fibre-reinforced polymer composites (FRPs), given that it is a non-contact, precise, low heat input, high-productivity, highly automated process. Currently, however, laser cutting of FRPs is not fully optimised and is not commonly used by industry. This report presents results of trials to develop and demonstrate multi-pass laser cutting and benchmark it against the competing processes of milling and water-jet machining. A detailed assessment of the cut edge quality and performance for all cutting methods is also provided.
