ABSTRACT:
A sound dampener for a disk brake assembly comprising a composite of vinyl ester and glass. Preferably, the composite is comprised of a region of woven glass sandwiched between a layer of vinyl ester and another layer of vinyl ester in which random strands of glass are embedded. The composite dampens the vibrations induced by the friction associated with the disk brake assembly to eliminate brake squeal. The composite also has low rates of thermal conductivity and thermal expansion which aid in reducing break squeal.
