摘要

A thermoformed contoured three-dimensional laminated structure (10) having improved sound absorbing characteristics and which can be formed with shorter mold cycle times includes a porous thermoformable fibrous batt layer (12) and a rigid foam layer (14). The laminated articles are suitable for use as decorative sound absorbing panels for automotive applications, and are well suited for use as vehicle headliners.
