Abstract : The primary goal in developing nondestructive test methods and techniques for evaluating reinforced plastics is the establishment of a thorough knowledge of the important material-energy interactions which occur in the composite system of interest. This has been applied to the quantitative nondestructive evaluation of 181 style, E-glass fabric reinforced laminates containing five resin systems, epoxy, phenolic, polyester, polybenzimidazole, and silicone. From this work has come the ability to predict Young's modulus and laminate volumetric composition. Observations and analysis of data crossplots and type of failure mechanisms in glass fabric laminates. The data obtained appear to be sufficient for developing a set of equations which will eventually allow the characterization of laminate composition and the prediction of design properties, i.e., tensile, compressive, shear, and flexural.
