The present invention discloses a flame-retardant, thermal-insulating, and fireproof material for batteries, and relates to a silicone rubber flame-retardant and thermal-insulating material, which comprises a flame-retardant and thermal-insulating layer and an impact-resistant layer, wherein the flame-retardant and thermal-insulating layer comprises organic silicone rubber, a ceramic-forming filler, a flame retardant, an auxiliary agent, and glass powders with different initial melting temperatures, and molten-state temperature ranges of the glass powders cover 300 °C to 1500 °C. Various glass powders with different molten-state temperature ranges are added to the material, so that when being burned to form a ceramic layer in the temperature range of 300 °C to 1500 °C, the fireproof material always has glass powders in a molten state. The glass powders in the molten state can timely fill holes and cracks that appear at different temperatures in the ceramic layer, and ensure the continuity, integrity, and compactness of the ceramic layer as far as possible, so that the fireproof material has the characteristics of quick ceramic formation at a low temperature and high temperature resistance of about 1500 °C. The problems that the existing glass powder has a single molten-state temperature range, holes are produced in the ceramic layer due to gasification of the glass powder at a high temperature, the structural compactness is reduced, and the ceramic layer is easily burned through are solved.

The present invention relates to sandwich panels used as aircraft interior parts. In addition to provide a finishing function, the sandwich panels need to have certain mechanical properties and have sufficient fire resistance to retard the spread of fire within the vehicle interior. The present invention provides an aircraft interior panel with skins comprising natural fibre reinforced composites based either on an inorganic thermoset resin or a thermoplastic resin. Such panels provide the required flame and heat resistance, allow easy recycling and disposal, are cheaper and offer significant weight savings over conventional sandwich panels.
