A method for detecting an impact at a structure (100), which is made of a fibre composite material. The method involves capturing a structure vibration of the fibre composite structure by means of at least one sensor (11a, 11b, 11c), wherein the fibre composite structure has not been excited by an actuator of a structure monitoring system, detecting an impact induced vibration characteristic or signature in the structure vibration by analysing the structure vibrations with respect to the frequencies and/or amplitudes by means of an evaluation unit (12), and detecting an impact event at the structure (100) as a function of the detection of the impact induced vibration characteristic. The evaluation unit compares sensor measurements to threshold frequencies / ranges. Preferably, the vibration sensors are strain gauge, acceleration, optical or piezoelectric sensors. Vibration or amplitude / frequency spectrums with signatures or characteristics which are indicative of an impact may be predetermined from experiment or test data analysis.
