Abstract
The use of composite materials in aircraft manufacturing is increasing, driven by the need for reduced weight and improved fuel efficiency. This trend extends to military aircraft, as defence manufacturers and suppliers seek to minimise operating costs. However, these composites are susceptible to various defects, which require the use of advanced Non-Destructive Testing (NDT) techniques for their detection and evaluation. Phased Array Ultrasonic Testing (PAUT) is such an NDT technique that provides precise defect characterisation, including delaminations, cracks, voids, and porosity. Active Thermography (AT) is an alternative NDT technique that is emerging as a non-contact and full-field technique for identifying such defects. PAUT and AT are complementary techniques, and a synergistic approach that combines their capabilities promises enhanced aircraft safety and composite structure reliability. This paper presents research findings using PAUT equipment and active infrared thermography for identifying and evaluating defects in composites. The presented combined approach is expected to improve aircraft safety and composite structure reliability in aerospace applications.
