Abstract
A moldable fibrous mat from which a permanently rigid product of predetermined shape can be molded by the application of heat and/or pressure. The mat consists essentially of base fibers and carrier fibers and a thermosetting ingredient, with the base fibers having a substantially higher softening temperature, if any, than the carrier fibers. The fibers intertwine to resist separation. The carrier fibers are bonded to the base fibers and to each other to form connections, the thermoset remaining dormant in the making of the mat. There is also disclosed a method by which the moldable fibrous mat is made and product made from the mat, which product may be of uniform density or have areas of differing density.
