Comparison of Nondestructive Testing Methods on Detection of Delaminations in Composites
Delamination is one of the most common defects in carbon fibre reinforced plastic (CFRP) components, such as those used in aircraft and wind turbine blades. To detect delaminations, different NDT methods such as ultrasonic (UT), eddy current (EC) scanning, flash thermography, and recent developed pulsed-eddy-current-(PEC-) simulated thermography are conducted for comparison and evaluation of th...
متن کاملSignal Reconstruction and Feature Extraction of Pulsed Eddy Current Thermography for Aerospace Composites
Pulsed eddy current (PEC) stimulated thermography is proposed as a powerful non-destructive evaluation (NDE) technique, allowing the operator to observe the heating developed from the eddy current distribution in a structure using infrared imaging, detecting defects over a relatively wide area within a short time. Some defects (impact, delamination, disbond or crack) commonly occur in aerospace...
متن کاملNDT characterisation of carbon-fibre and glass-fibre composites using non-invasive imaging techniques
The prerequisite for more competent and cost effective transport has led to the evolution of innovative testing and evaluation procedures. Non-destructive testing and evaluation (NDT & E) techniques for assessing the integrity of composite structures are essential to both reduce manufacturing costs and out of service time of transport means due to maintenance. Smart methods for assessing the in...
