A multi-laminar material for the containment of heat and/or flame comprises a layer of ceramic material and a layer of carbon material. The ceramic is preferably alumina fibre paper. The carbon material is preferably carbon felt produced by pre-oxidising polyacrylonitrile. The preferred laminate comprises (in order) a structural layer, ceramic layer and carbon layer, and also adhesive or sealant layers. The preferred structural layer comprises a coated core, preferably a cellular metal, alloy or aromatic polyamide core, especially aluminium alloy honeycomb, coated with carbon fibre reinforced (CFR) thermoset epoxy or phenolic resin. The laminate is a fire guard, especially for a traction battery pack 12 for a motor vehicle with an adjacent fuel tank 14. |
