Paper Abstract

Composite joints with specially designed viscoelastic inserts could act as effective vibration absorbers. The damping performance of a novel viscoelastic material used as an interlayer in a composite Top-hat stiffener is studied following experimental and FE modal analysis. The damping performance of the same material embedded inside Aluminum Beams in different shapes but constant volume is also evaluated. Results from the experimental and numerical analysis are discussed.
