Abstract : A comprehensive report on the subject of acoustic emission (AE) as applied to characterization and testing of composite materials and structures has been written. First, an extensive bibliography of over 300 references of the literature in this field is presented. This part includes author and subject indexes as well as a guide to the more significant literature. Second, the technical principles which must be adhered to in order to do a technically sound AE test on a composite sample are described is some detail. This part includes all aspects of standard testing and data analysis. Third, a representative survey of typical proven applications of AE to composites is presented. This survey has two basic divisions: (1) the application of AE to material studies of composites; and (2) the application of AE to quality control and/or nondestructive evaluation. Finally, a review of the progress in the research areas of AE and composites is given. This review covers the specific areas which have not yet been brought to maturity. In appropriate cases critical comments are made as well as suggestions for future work.
