A composite product includes gypsum in an amount of 60 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.

1. A core for a fire rated door comprising: a fire resistant center panel having a bottom, a top, a first side, a second side, a first end and a second end, wherein the fire resistant center panel is made of a first fire resistant material comprising gypsum in an amount sufficient to provide fire resistance wherein the amount is 60 to 85% by weight, fibers in an amount of 1.5 to 5% by weight substantially homogeneously distributed through the composite, an aggregate in an amount of 10 to 25% by weight substantially homogeneously distributed through the composite, a starch in an amount of 2 to 7% by weight and a rheology-modifying agent in an amount of 0.5 to 4% by weight; andan extruded fire resistant border attached to the first side, the second side, the first end and the second end of the fire resistant center panel, wherein the extruded fire resistant border is made of a second fire resistant material 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. 2. The core as recited in claim 1, wherein the first fire resistant material further comprises a vermiculite or clay in an amount of 1 to 10% by weight substantially homogeneously distributed through the composite. 3. The core as recited in claim 1, further comprising: a notch in the first side of the fire resistant center panel; anda fire resistant lock block disposed within the notch and attached to the fire resistant center panel and the extruded fire resistant border, wherein the fire resistant lock block is made of the second fire resistant material. 4. The core as recited in claim 1, wherein the extruded fire resistant border is attached to the fire resistant center panel with a set of male-female connectors formed in the extruded fire resistant border and the fire resistant center panel. 5. The core as recited in claim 4, wherein the male-female connectors are triangular-shaped, curved-shaped, rectangular-shaped, angled, tongue-and-groove, or a combination thereof. 6. The core as recited in claim 4, further comprising a top panel attached to the top of the fire resistant center panel and the extruded fire resistant border, or a bottom panel attached to the bottom of the fire resistant center panel, or both the top panel and the bottom panel. 7. The core as recited in claim 6, wherein the one or more protective layers comprise one or more gypsum boards, one or more metallic sheets, one or more lead sheets, one or more Kevlar sheets, one or more ceramic sheets, a layer of urethane foam, a layer of graphite, a wire mesh or a combination thereof. 8. The core as recited in claim 7, wherein the fire resistant center panel and the extruded fire resistant border are coated with an intumescent or fire resistant material. 9. The core as recited in claim 1, wherein the extruded fire resistant border comprises: a first stile;a second stile;a first rail attached to the first stile and the second stile; anda second rail attached to the first stile and the second stile.
