Abstract
The resin content of an organic resin-matrix composite material is measured nondestructively by nuclear magnetic resonance. A specimen of the composite material is placed into a constant magnetic field and subjected to a radio-frequency magnetic field pulse. The response of the material is indicative of the amount of organic resin that is present. The response may be used as a feedback signal to control the operation of a manufacturing machine.
