In this work a microwave sources were used to heating the water inside composite materials in order to detect with thermographic technique the damaged area of materials. The tests were performed with traditional thermographic techniques and the new technique proposed on CFRP and GFRP damaged specimens. A new algorithm was developed to processing the thermographic data obtained by microwave stimulation in order to evaluate in automatic mode the damaged areas of analyzed component. A microwaves lock-in thermography was carried out to detect the impact damages on composite material specimen using a algorithm based on FFT analysis.

Abstract
In this work a microwave sources were used to heating the water inside composite materials in order to detect with thermographic technique the damaged area of materials. The tests were performed with traditional thermographic techniques and the new technique proposed on CFRP and GFRP damaged specimens. A new algorithm was developed to processing the thermographic data obtained by microwave stimulation in order to evaluate in automatic mode the damaged areas of analyzed component. A microwaves lock-in thermography was carried out to detect the impact damages on composite material specimen using a algorithm based on FFT analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
