Abstract
In this work, nondestructive methods for the quantitative evaluation of composite microstructure are described. Parameters of interest in this regard might include fiber volume fraction, porosity, degree of cure (thermoset resins) and crystallinity (thermoplastic resins). These methods rely upon the high degree of accuracy which can be obtained with ultrasonic measurements of acoustic velocities; hence the mechanical properties of the material, and well established composite micromechanics relationships between elastic properties and composite microstructure. This results in sets of nonlinear equations which can be solved for the unknown microstructural parameters.
