Abstract (en)
[origin: EP2612969A2] Fiber-reinforced composite mats are described that include a non-woven web of fibers. The web of fibers may include a first group of fibers having an average fiber diameter from about 8 µm to about 25 µm, and a second group of fibers having an average fiber diameter from about 0.5 µm to about 6.5 µm. A binder bonds together the non-woven web of fibers into the fiber reinforced composite having an air permeability of 250 cfm/ft 2 or less. Also described are gypsum boards that include one or more facers affixed to at least one surface of the gypsum board. The facers may be made from the above, described fiber-reinforced composite mats.
