This report contains the essential findings of a comprehensive survey of the state-of-the-art in nondestructive evaluation NDE of fiber reinforced epoxy composites with emphasis on the types presently used or planned for use in Army helicopter components. Primary consideration is given to the NDE of glass fiber composites because of its extensive use in the fabrication of advanced helicopter rotor blades with secondary consideration given to the NDE of Kevlar, graphite, and boron reinforced epoxy. A computer search of the literature was performed to compile an extensive bibliography of source documents. Pertinent documents were reviewed and NDE results categorized according to NDE methodology and type of composite. For each composite type, tables were developed listing defects and property variations detected by various NDE methods. These tables along with literature references are included in the report. The status of NDE of fiber reinforced epoxy composites with respect to available techniques, ongoing research, and projected future needs is reviewed and summarized.
