Abstract
Disclosed is a system and method for constructing fibrous mats. In accordance with the disclosure, continuous lengths of filament are pre-coated with a liquefied thermoplastic. The pre-coated filaments are then laid down upon a belt to form a fibrous mat. The filaments can be laid down in continuous lengths or they can be chopped into discontinuous lengths. The filaments are heated after they have been laid down in order to re-liquefy the thermoplastic and facilitate bonding between intersecting fibers. The disclosure further relates to a system and method for incorporating constructed fibrous mats into a composite building board.
