EPR Imaging Investigations of Glass Epoxy Composite Materials and Tracer Diffusion in Ceramics
Nondestructive evaluation (NDE) of flaws and defects in non-metallic materials including polymers, ceramics, semiconductors and composites is important for scientists and engineers involved in a wide variety of applications. Magnetic resonance techniques are potentially powerful tools for this purpose. The ability to map out details of internal structure in a noninvasive manner using Nuclear Magnetic Resonance (NMR) has revolutionized diagnostic medicine. Some of the same benefits are realizable for the NDE of solid materials using Electron Paramagnetic Resonance (EPR) and EPR Imaging (EPRI) . This technique has the potential to yield three-dimensional images of manufacturing defects and damage sites in nearly any non-metallic solid.
