Non-Destructive Evaluation of Aircraft Structural Components and Composite Materials at DSTO Using Sonic Thermography

摘要

This report outlines the results of a series of non-destructive evaluations using sonic thermography. It examines the detection of closed cracks, delaminations, impact damage and other defects in a variety of structural components and composite materials used in aircraft structures. The results confirm the efficacy of the technique and highlight its potential to fill some of the capability gaps that currently exist in relation to challenging non-destructive inspection problems.
