Fibre reinforced polymer (FRP) components can have visible or non-visible damages because of an impact, crush, or fatigue during the regular operation hours. These components or structures have to be continuously monitored in order to ensure an early detection of deterioration. This paper uses the vibration decay rate experimentally as a method to detect damages in a FRP component. Measurement of reverberation time RT60 is executed in three different damage conditions of a specimen made of fibre reinforced polymer. The conditions of the specimen vary based on the damage existence in it. The major concern is on predicting damages presence by the measured data. The resulted data showed a clear difference among the three conditions proving the damages existence.
