Abstract
In 2012 SABCA Limburg N.V., a Belgian aerospace company, started with the production of the Flap Support Fairings for the A350-800 commercial aircraft. These parts are manufactured using a combination of honeycomb and carbon fiber pre-preg laminates. After part curing all fairings are inspected for defects. The most straightforward and common inspection method is the 'tap test'. As this inspection method is labor intensive and also subject to interpretation, different alternative methods for inspection will be compared. Key requirements for these alternative methods remain validity, reliability and objectivity. This paper will focus mainly on two inspection methods that are used in the aerospace industry: ultrasonic inspection and thermography. Ultrasonic inspection on composite parts is largely used in the composite manufacturing industry to detect porosities, delaminations, cracks etc. Thermography has only been introduced more recently to inspect composite aerospace components. Research shows that it is possible to detect subsurface defects with the aid of thermography. To validate this research, a comparison is made between these two inspection methods using the A350 Flap Support Fairings as test pieces. Both methods are also compared using IRP panels.
