Acousto-ultrasonics for defect assessment of composite materials

Abstract :

The research presents a study of the application of the acoustic-ultrasonic non-destructive test method to composite structures. Internal defects in high performance composites have the potential to cause significant performance degradation. A series of experiments were used to assess the method’s capability of detecting defects such as that caused by impact and delamination. In addition, the experiments proved that the acousto-ultrasonic method can be used to quantitatively determine a material’s anisotropy, variations in resin and fibre orientation. It was also demonstrated that the use of selective frequencies can be used to improve the detection of internal defects.
