Abstract
A method for producing laminate composite materials, as well as the laminate composite materials produced by this method and their use are described. The laminate composite materials are sandwich-like in construction and based on halogenated polymers and comprise a first laminar structure formed from halogenated polymer and a second laminar structure formed from halogenated polymer as well as at least one textile mat structure based on inorganic fibres, which is disposed between the first and the second laminar structure. The textile mat structure based on inorganic fibres comprises regions with high air permeability and regions with low air permeability, through which the two laminar structures formed from halogenated polymer are monolithically bonded together.
