Acoustic Emission for Damage Detection in USAF Composite Structural Components.

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.
