This paper describes an evaluation of promising, mobile NDI (non-destructive inspection) methods for the inservice inspection of composite aerospace structures. The evaluation makes use of carbon fibre reinforced specimens representative for primary composite structures in current and next generation aircraft and helicopters. The specimens comprise solid laminates and sandwich structures with/without stiffeners, and include relevant damage types such as impact damage, interply delaminations and disbonds. A range of promising, mobile NDI methods are evaluated including visual inspection, vibration analysis, ultrasonic inspection (including different phased array methods), shearography and thermography inspection. An important aspect of the evaluation is the capability of the NDI methods for the detection, sizing and depth estimation of the defects present in the specimens. Further evaluation parameters are the portability of equipment, field of view, couplant requirements, speed of inspection, level of training required and the cost of equipment. The paper gives an overview of the advantages and limitations of the different NDI methods, and concludes with general guidelines for the inservice inspection of composite aerospace structures.
