The eddy current non-destructive inspection technique can be used effectively on fibre metal laminates. It uses the principle of electromagnetic induction, i.e. the interaction between a magnetic field with an electrically conductive object. With this method, the different Fibre Metal Laminate types can be easily discriminated and fatigue cracks in the metal layers of the laminate can reliably be detected in, e.g. plain material, lap joints and spliced laminates.
