A fire resistive and insulating bonded composite structure includes a binder made from a mixture of a weak acid and a powdered base metal oxide wherein the acid and metal fuse as a mixture under an exothermic reaction into the binder. A fibrous cellulose material is encapsulated within the binder and rendered non-flammable thereby. The subject invention further provides a method of making the bonded composite structure including the steps of mixing the weak acid and powdered base metal oxide, encapsulating the fibrous cellulose material within the binder and rendering the fibrous cellulose material non-flammable thereby, forming the slurry mixture into a predetermined form, and setting the formed mixture into a solid.

A bonded composite structure consisting essentially of: a binder made from a mixture of mono aluminum phosphate and a powdered base metal oxide at a ratio of 3:1 to 1:3 by weight of powdered base metal oxide to weak acid, said acid and metal fusing as a mixture under an exothermic reaction into said binder without releasing any noxious gases, and intact fibrous cellulose material particles mixed throughout said binder at a ratio of 1:1 to 1:6 of said fibrous material to said weak acid and encapsulated within said binder and rendered non-flammable thereby in a single essentially homogeneous layer, said structure having a melting temperature greater than 3000°F. A method of making a bonded composite structure consisting essentially of the steps of: mixing mono aluminum phosphate and a powdered base metal oxide which fuse as a mixture under an exothermic reaction into a binder; mixing fibrous intact cellulose particles into the binder to suspend the fibrous cellulose particles throughout the binder while encapsulating the fibrous cellulose particles within the binder and rendering the fibrous cellulose particles non-flammable thereby; forming the mixture into a substantially homogenous layer of intact fibrous particles encapsulated in the binder; and setting the formed mixture.
