Abstract
A fibrous composite material comprising carbon fibres and chemically delaminated vermiculite lamellae and production of the material by applying a suspension (preferably an aqueous suspension) of the lamellae to carbon fibres and removing the liquid medium from the suspension. The composite material is useful for the insulation and fire-protection of substrates.
Claims13
A fibrous composite material consisting essentially of carbon fibres and lamellae of chemically delaminated vermiculite wherein the fibres comprise at least 10% by weight of the composite.
A material as claimed in claim wherein the vermiculite lamellae are substantially all of the maximum dimension below 50 microns.
A material as claimed in claim wherein the fibres are present in the form of a layer of fibrous material.
An article of manufacture protected from damage by heat or flame comprising a flammable and/or low-melting substrate and a fibrous composite material comprising carbon fibers and lamellae of chemically delaminated vermiculite wherein said fibrous composite material is provided as a loose covering not bonded to said substrate.
An article of manufacture protected from damage by heat or flame comprising a flammable and/or low-melting substrate and a fibrous composite material comprising carbon fibers and lamellae of chimically delaminated vermiculite wherein said fibrous composite material is bonded to and laminated with said substrate.
