Abstract:

Five methods of non-destructive material evaluation NDE were used to inspect various forms of damage commonly found in aerospace fiberglass composites voids, edge and sub-surface delaminations, surface burning, and cracking. The images produced by X-ray, X-ray Computed Tomography, terahertz THz imaging, ultrasound, and flash IR thermography were analyzed for the detection of defects. Test results and analysis of each NDE methods capabilities provide a comparison study of conventional techniques versus the emerging technology of THz imaging for the non-destructive evaluation of aerospace composite materials. A comparison guide to the five methods damage detection effectiveness for fiberglass composites is provided by defect type.
