ABSTRACT:
Thermal damage in resin-matrix composite materials is detected using a low field NMR nondestructive testing technique. The technique involves subjecting the resin-matrix composite material to an NMR measurement of the spin-lattice relaxation (T.sub.1) at a low magnetic field strength and/or the spin-lattice relaxation of local field order (T.sub.1D) at any field strength. Thermal damage is evident as an increase in T.sub.1 and T.sub.1D.
