The paper is devoted to the identification of anomalous porosity level on composite structures by thermography. The thermal properties mapping of local diffusivity is used for this purpose. Experimental results obtained in different experimental conditions are reported. These results are compared with findings given by Ultrasounds. A procedure for porosity classification on carbon fibre reinforced plastics by means of two-dimensional wavelet transform and statistical analysis is presented.

Abstract
The paper is devoted to the identification of anomalous porosity level on composite structures by thermography. The thermal properties mapping of local diffusivity is used for this purpose. Experimental results obtained in different experimental conditions are reported. These results are compared with findings given by Ultrasounds. A procedure for porosity classification on carbon fibre reinforced plastics by means of two-dimensional wavelet transform and statistical analysis is presented.File in questo prodotto:
