Phase I

Contract Number: N60921-85-C-0257
Start Date: 9/10/1985    Completed: 00/00/00
Phase I year
1985
Phase I Amount
$49,724
The structural integrity of graphite epoxy composites can be validated by measurement of eddy-currents induced in electrically conducting fibers. Eddy-currents are diminished in damage regions of a composite structure because ruptured fibers do not provide an electrically conducting path. The program proposed herein seeks solutions to practical problems and obstacles to the realization of a practical instrument for inspection in the fields.
