The invention discloses a fire resistant composite material comprising inorganic particles well dispersed in a polymer having reactive functional groups. The inorganic particles also contain reactive functional groups, originally or after surface modification, that can react with the corresponding reactive functional groups of the polymer to form organic/inorganic composite materials. When the composite material is burned or under fire exposure, the polymer forms a char layer and the inorganic particles radiate absorbed heat. The inorganic particles also strengthen the mechanical properties of the structure through the reaction between inorganic and organic materials, so that the formed char layer is firm and can maintain its structural integrity without peeling off or cracks, effectively preventing direct heat transferring into the interior parts. The fire resistant material is not only flame retardant but also protective toward the interior materials. As a result, the duration of fire resistant ability is tremendously improved.
