Kraiburg GmbH & Co. (Waldkraiburg, Germany) had an interactive stand displaying laminate panels both with and without the company’s Kraibon lightweight rubber damping material. When whacked with a drumstick, the panels exhibited dramatic acoustic differences. Kraibon is a thin film of uncured rubber added to the laminate stack, which cures with the laminate. Aimed at automotive parts, the very thin rubber material ply is significantly lighter than the aluminum butyl vibration insulation material typically added by the auto industry for acoustical damping and NVH (noise/vibration/harshness) control. And, Kraibon improves composites’ damage tolerance, says the company.
