Fibre reinforced plastic (FRP) sandwich composite materials are widely used in the construction of aerospace and marine structures. A cause for concern however in the use of these materials is the fact that internal defects can occur between layers which, if not identified early on, can lead to rapid structural degradation. This paper describes an approach, based on measuring structural vibration characteristics, to identify these internal defects. The idea being that an occurrence of a defect of this nature, within the structure, would alter the singularity properties of the structure’s vibration signal. Using the wavelet transform modulus maxima method to perform multifractal analysis, a spectrum of the distribution of the singularities p...
