Dynamic Response and Acoustic Fatigue of Stiffened Composite Structure

Abstract

This paper summarizes the results obtained from acoustic fatigue and dynamic response tests and the L-1011 composite aileron and integrally stiffened graphite/epoxy panels. The nature of the damping in integrally stiffened composite panels, its theoretical prediction and its implication on internal noise are briefly discussed.
