1. Claims for the Contracting States : BE, CH, DE, FR, GB, IT, LI, LU, NL, SE Consolidated microporous material comprising a stack of fibres deposited on a perforated rigid substrate, the said stack containing carbon fibres and being consolidated by a fluorine-containing polymer, characterized in that the carbon fibres have a length distribution such that the length of at least 80% of the fibres corresponds to the mean length of the said fibres to within about plus or minus 20%. 1. Claims for the Contracting State : AT Process for obtaining a consolidated and microporous material, comprising the deposition of a fibrous structure on a perforated rigid substrate, characterized in that it comprises the deposition by filtration of a suspension containing carbon fibres and a binder based on fluorine-containing polymers on a perforated rigid substrate, the carbon fibres having a length distribution such that the length of at least 80% of the fibres corresponds to the mean length of the said fibres to within about plus or minus 20%. |
