Abstract:
A cementitious board (100) and a method for manufacturing the cementitious board (100) has a facing layer (105) having an areal weight of about 300 grams/M2, and an air permeability rating of no greater than about 300 CFM/ft2 (FG 436-910 test method). The facing layer (105) reduces the penetration of a slurry (28) of cementitious material during the manufacture of the board (100), and passes water vapor from the slurry (28) while the slurry (28) cures. Binders, coatings or saturants (107) decrease pore size, increase or decrease the contact angle of liquids, promote adhesion to cementitious cores (101), promote adhesion to the facing layer (105) and promote adhesion or affinity to adhesive compositions used to join cementitious boards to exterior insulation systems and exterior finishing systems (EIS and EIFS).

Abstract:
The present invention relates to mutidirectionally reinforced fiber preforms that conform easily to complex curvatures, such as, composite turbine fan cases, jet engine containment rings, aircraft fuselage frames, aircraft window frames, and flanged rings for attaching nacelles to aircraft engines. The present invention provides mutidirectionally reinforced shape woven preforms with improved strength for composite structures that are axisymmetric as well as non-axisymmetric in nature. The invention is a preform used to reinforce a composite structure which includes a contour woven fabric portion, bi-axially braided, tri-axially braided or bias fabric portion, and/or a polar woven fabric portion, and a method of making thereof. The preform may optionally include a three-dimensionally woven portion. The combination of different forms of fabrics allows the preform to be produced without cutting and darting of the individual plies. Eliminating these cuts and darts improves the strength and performance of the resulting structure.
