Abstract
Abstract A fibrous composite material in the form of a three-dimensional block comprising a mass of combustible fibres and lamellae of a layer mineral, a method for the manufacture of the fibrous composite materials by applying lamellae of a layer mineral, preferably from a suspension, to combustible fibres and forming the fibres and layer mineral into a three-dimensional block, and use of the fibrous composite materials as insulating materials and for the fire protection of su bstrates.
