The mechanisms that can cause the destruction of a Remotely Piloted Aircraft (RPA) are investigated through experiments with a 2 kW fiber optic laser and a 0.35 mm thick carbon fiber/epoxy plate. It was found that 1 s of resin irradiation, with fluences of 1 to 2 kJ/cm2, are capable to damage the resin’s integrity. For carbon fiber sublimation, a fluence of 20 kJ/cm² is required. Related to the interaction time, tree damage mechnisms can be found: structural failure, combustion and ablation.
