Eddy current testing in CFRP production

Eddy current testing has established itself as a nondestructive test method in CFRP production. By exploiting the electrical conductivity of carbon fibers, it is possible to detect fiber orientation, surface weight, area density and fiber volume content as well as ripples and folds in stacks, preforms and composite components. This article presents recent applications and discusses future perspectives for deployment in CFRP production.
