Jezzard P., Wiggins CJ., Carpenter TA., Hall LD., Barnes JA., Jackson P., Clayden NJ.
Nuclear magnetic resonance imaging has been used as a method of void detection in carbonfibre reinforced polymer composites. This is accomplished by observation of signal from water molecules which have ingressed into surface-connected defect regions within the polymer composite. Problems associated with the conductivity of these samples are discussed, along with methods of overcoming those difficulties. © 1992 Chapman & Hall.
