A composite product includes gypsum in an amount of 70 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.

The fire resistant composite product as recited in claim 8, wherein the composite does not include any cement or flyash. 14. A fire resistant composite product comprising: a composite comprising gypsum in an amount sufficient to provide fire resistance wherein the amount is 70 to 90% by weight, glass fibers in an amount of 2 to 10% by weight substantially homogeneously distributed through the composite, cellulose fibers in an amount of 2 to 8% by weight substantially homogeneously distributed through the composite, polyvinyl alcohol fibers in an amount of 1 to 4% by weight substantially homogeneously distributed through the composite, polypropylene fibers in an amount of 0.3 to 4% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight;the composite is caused or allowed to cure to form a cured composite; andthe cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel, wherein the fire resistant component is selected from a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, and a door insert. 15. The fire resistant composite product as recited in claim 14, wherein the fibers have a diameter of 6mm to 25mm. 16. The fire resistant composite product as recited in claim 14, wherein the rheology-modifying agent comprises hydroxypropoyl methyl celluose (HPMC), methyl hydroxyethyl cellulose (MHEC), hydroxyethyl cellulose (HEC) or carboxymethyl cellulose (CMC). 17. The fire resistant composite product as recited in claim 14, wherein the fire resistant component has a cross-sectional thickness of 0.125 inches to 2 inches, a width of 1 inch to 4 feet and a length of 3 to 10 feet. 18.
