SMOOTH REINFORCED CEMENTITIOUS BOARDS AND METHODS OF MAKING SAME.

摘要

A composite fabric for use in reinforcement (18) of cementitious boards and similar prefabricated building wall panels (10). The fabric includes an open mesh first component (20) of continuously coated, high modulus of elasticity strands and a nonwoven second component (22) fabricated from alkali resistant thermoplastic material. The high modulus strands of the first component are preferably bundled glass fibers encapsulated by alkali and water resistant thermoplastic material. The composite fabric also has suitable physical characteristics for embedment within the cement matrix of the panels or boards closely adjacent the opposed faces thereof.
