Abstract:
The efficiency of two ways to reduce vibration and sound emission of a plate made of paper-laminated plastic (high-pressure laminate) has been investigated. It has been found that the inclusion of a polymer polyvinyl acetate film in the plastic structure or using constrained damping layer treatments based on polyvinyl acetate film and aluminum foil or plastic leads to a significant improvement in its vibroacoustic characteristics. The greatest reduction in vibration and sound emission was obtained when applying a coating with aluminum foil whose thickness was six times less than that of the damped plastic plate.
Keywords:
vibration absorption, sound emission, vibration-absorbing composites, high-pressure laminate.
