Abstract
Provided are a method and device for detecting arrangement disorder of fibers in a conductive composite material. A coil () is disposed at a position at which the coil () faces the conductive composite material, and thereby a current can be applied to the conductive composite material. Thus, work or the like for attaching electrodes to the conductive composite material is not required. As a result, the arrangement disorder of the fibers in the conductive composite material can easily be detected. A method for detecting meandering of fibers in a conductive composite material includes a step of disposing a magnetic field sensor () at a position at which the magnetic field sensor () faces a surface (Sa) of the conductive composite material such that a direction (D) of a magnetosensitive axis is horizontal with the surface (Sa) and is parallel to coil faces (). Therefore, the magnetic field sensor () measures a magnetic field, and thereby a portion at which the arrangement disorder of the fibers in the conductive composite material is present can be detected.
