Eddy current testing of cfrp structures

Article preview

Specific features of technological processes of manufacturing carbon-fiber-reinforced constructions can cause non-observance of proportions of a reinforcing material and binding, a de-viation of wall thickness, porosity and rupture of threads. Difficult service conditions can lead to internal volume stratifications and formation of cracks. Above told defines necessity of carrying out of complex control of carbon-fiber-reinforced constructions at all stages of their life cycle. It is expediently to use the Eddy Current NDT for that purposes. The device with set of Eddy Current Phase and Eddy Current Frequency transducers have been developed for measurement electro-conductivity and wall thickness of constructions, detection of cracks and internal volume stratifications, and also their depth and the area. Principles of calculation and optimization of parameters of transducers, influence suppression of stirring parameters are considered.
