INTERNALLY DAMPED THIN-WALLED, COMPOSITE LONGITUDINAL MEMBER HAVING DEDICATED INTERNAL CONSTRAINING LAYERS

摘要

An internally damped structure having a thin, segmented layer of high modulus composite material acting as a constraining layer and bonded on both sides to layers of viscoelastic damping layers acting as shear layers. The arrangement forms a triple layer sandwich, which is embedded in the wall of the structure. A compliant filler is positioned between adjacent segments of the composite constraining layer. In an alternate embodiment two such sandwich arrangements are embedded in the wall of the structure.
