A laminated panel-type structure particularly suited for vehicle interior applications such as headliners and door panels has a multiple denier
polyester fiber core and randomly oriented structural reinforcing fibers. The laminated structure has superior sound attenuation properties resulting from a core of intertwined
polyester fibers of differing deniers, with preferably relatively larger denier fibers on exterior areas of the core and some bicomponent fibers, short non-woven reinforcing
fiber strands which are randomly attached and intertwined with the core on opposing major sides of the core, an impervious
polymer film with a low melt layer which retains the reinforcing fibers against one side of the core and is attached to a scrim layer, and a
polymer web on an opposite side of the core which retains the reinforcing
fiber strands on the opposing major side of the core and to which a cover stock is applied. The invention further includes a method of manufacturing the laminated structure wherein the various
layers are sequentially unfurled from spools, passed through nip rollers at points of various subcombinations of materials and
layers, the reinforcing fiber strands are randomly distributed on to the carrying
layers from hoppers or directly from a fiber chopping device, and the completed laminated structure is
cut and molded.
