<P>PROBLEM TO BE SOLVED: To provide methods for enhancing one or more physical properties of wet-laid or dry-laid fiber mats, such as a glass fiber, cellulosic or polymeric fiber mats, and to provide the fiber mats produced according to such processes. <P>SOLUTION: Certain embodiments of the methods involve vibrational compression of a wet-laid or dry-laid fiber mat. In some embodiments, the methods produce a fiber mat having increased apparent density and/or tensile strength as compared to a mat that has not been vibrationally compressed. Exemplar fiber mats suitable for use in the disclosed methods include, for example, glass, polyolefin, ethylene terephthalate, or cellulose fibers, or mixtures thereof. Glass, cellulosic, or polymeric fiber mats that are structurally improved by the disclosed methods are also disclosed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
