Abstract: Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. Upon application of heat to the boards or blanks or parts in the mold, the binder material is melted so as to allow the nonwoven material to expand in one or more directions, and thereby fill all or part of the mold. Upon cooling, the binder material again hardens, and the molded component is retrieved from the mold.
