Abstract

A wide bandwidth 1-3 connectivity piezocomposite air transducer has been used to detect laser-generated ultrasound in a variety of composite materials. Through thickness waveforms in various carbon fibre reinforced polymer (CFRP) composite plates will be presented, as well as a selection of Lamb waves. Signals were also obtained in samples of pultruded glass fibre reinforced composite of different thickness. Using the laser/air-transducer system, images were obtained of machined defects and delaminations by conventional C-scanning methods, and tomographic reconstruction techniques.
