Abstrakt

Carbon fibre textiles are a class of high performance materials that for example are used in aerospace applications. Such applications have exceptionally high requirements regarding quality and reliability of carbon fibre textiles. Eddy current testing is a non-destructive testing method, which can be applied to both pure textile as well as the cured carbon fibre reinforced composite. However, the resulting data is hard to interpret because the local anisotropic conductivity and permittivity divert the signal from one of a simple metal. Simulation can help to understand the complex current paths in the carbon fibre textile and their influence on the sensor signal. Feasible modelling strategies are discussed, implemented, and compared to experimental results of regularly occurring faults in the textile, like gaps in different depths.
