  • Method and apparatus for testing fastener arcing and sparking
    Patent number: 4916401
    Abstract: A method and apparatus for testing arcing and/or sparking of a fastener installed in a carbon fiber composite (CFC) panel. The fasteners are installed in a test panel which is attached to a light-tight enclosure including a camera. Current is injected to the fasteners through current injection tabs attached to each of the fasteners from the outside of the enclosure. As the current level injected from a current source is varied, the camera records images of the manner in which electrical arcing and/or sparking occurs between the fastener and the test panel.
