A device, system and method for detecting flaws in a magnetic material includes a wheeled scanner having two detectors and arranged for travel over a flat surface. The first detector is a horizontal magnet-sensor arrangement that generates a magnetic field in a direction generally parallel to a central horizontal axis of the scanner. The second is a vertical magnet-sensor arrangement that generates a magnetic field in a direction generally perpendicular to the central horizontal axis of the scanner. A set of computer executable instructions uses data collected by the first detector to detect a flaw in the magnetic material and data collected at a same time by the second detector to determine a location of the detected flaw relative to a top and bottom surface of the magnetic material.

Velocity independent two-component magnetic flux leakage detective system

A method of making a fiber reinforced composite material having a two-part liquid solution forming magnetic nanoparticles. The method includes the steps of preparing a fiber reinforced composite having dispersed fibers and a polymer matrix and having a plurality of vascular channels therethrough. A first liquid solution is incorporated in at least one of the vascular channels and a second liquid solution is incorporated in at least one other of the vascular channels. When the liquid solutions are joined together because of damage or cracking to the composite, the liquids form a ferrous magnetic material. Non-destructive evaluation of internal damage to the fiber reinforced composite material may be accomplished by magnetic field disturbance detection, thermal detection, or visual detection.
