Characterization of Carbon Fibre Reinforced Composite by Means of Non-Destructive Eddy Current Testing and FEM Modeling
The limitation of non-destructive methods for the inspection of carbon fibre reinforced plastic (CFRP) composites is a major problem for many practical applications of the material, especially in the aircraft industry. This paper presents a study which is directed towards non-destructive characterization of CFRP using eddy current methods. The relationship between the signal from different types of inductive probes and the microstructure of CFRP samples has been observed. The measurement of a bulk equivalent electrical conductivity of the material was based on the Deeds and Dodd?ˉs analytic solution, which provides the fundamentals for the prediction and detection of fibre fracture and material defects. Characterisation of the fibre direction has also been performed on unidirectional and multidirectional CFRPs using a highly directional probe. Finally, 3D finite element method (FEM) computer simulations have been developed to demonstrate the coupling of the probes and samples, and to support the experimental method.
