CHARACTERIZATION OF LAMINATE COMPOSITION AND PREDICTION OF DESIGN PROPERTIES NOW POSSIBLE USING METHODS AND APPROACH OF NONDESTRUCTIVE TESTING,

Abstract

In studies conducted on glass fabric reinforced laminates, the long-standing problems of laminate compositional characterization and properties variability have yielded to the methods and approach of quantitative nondestructive testing (NDT). The investigation included 181 style, E-glass fabric with five resin systems, epoxy, phenolic, polyester, polybenzimidazole, and silicone. The ultrasonic and gamma radiometric NDT methods provided more than 20,000 quantitative units of data for use in correlations with design properties derived from tensile, flexural, shear, hardness, glass volume content, resin volume content, and porosity volume content destructive tests. As a result of this work, the feasibility of developing an extensive set of practical equations for the complete characterization of reinforced plastics materials and hence the prediction of design properties has been shown.
