Abstract
A method for manufacturing a preform having a desirably uniform distribution of structural forms (for example and without limitation, particles, flakes, and fibers) therethrough. The method according to the present invention includes using an electrical charge reaction between cationic and anionic agents (such as, without limitation, cationic and anionic polymers) to cause the structural forms to floc or clump together in a mass in which the structural forms are desirably uniformly distributed therethrough. The flocculent mass is then dewatered and/or dried to form a preform that is ready for further processing.
