Abstract

A composite wrap is provided for damping vibration in an elongated quill shaft having a cylindrical body. The composite wrap includes interior layering for disposition about a cylindrical body, exterior layering configured to define an exterior composite wrap shape and sequential cured-in-place, vibration damping, fibrous epoxy layers. The sequential cured-in-place, vibration damping, fibrous epoxy layers are radially interposed between the interior and exterior layering to dampen vibrations of and/or to adjust a resonance frequency of the cylindrical body.
