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.

A soft, flexible, handleable fibrous mat from which a permanently shaped product can be molded by the application of predetermined heat and pressure in a compression molding operation, said mat consisting essentially of cellulose base fibers, and means for linking and bonding and for resisting separation of said base fibers and adding tensile strength to said mat including carrier fibers intertwined with said based fibers and bonded to said base fibers and to each other forming connections therebetween, said mat having, in addition to said base fibers and means for linking and bonding, a dormant, uncured thermosetting ingredient, said thermosetting ingredient having a curing temperature not greater than the temperature of said compression molding operation so that said thermosetting ingredient will cure when said mat is subjected to said heat and pressure in said compression molding operation.
