Abstract
Abstract A fibrous composite material of essentially two-dimensional form in the form of individual fibres, sheets or layers comprising combustible fibres and lamellae of a layer mineral of size below 50 microns, a method for the manufacture of the fibrous composite materials by applying lamellae of a layer mineral to the fibres preferably from suspension followed by removal of the liquid phase of the suspension, and use of the fibrous composite materials for the fire-protection of substrates.
