Abstract : Filamentary composite materials, such as boron fibers in an epoxy matrix, are being used in modern USAF airframes. The objective of this project the development of a prototype acoustic emission system, including amplitude and frequency discrimination,. which would provide definitive results and form the basis of a laboratory tool for monitoring tests of composite coupons and small components.
