  • Patent number: 9796167
    Abstract: A method of fabricating an artifact (15) includes treating natural fibers (110) with a non-halogenated flame retardant agent (120), the fibers (110) also being treated with a smoke suppressant (120). At least one pre-preg is formed (170, 180) from the treated natural fibers and from a resin composition (160) including a smoke suppressant (150) admixed therein (160). An uncured artifact is formed from a core or substrate (12) and the pre-preg, which provides a skin, and is cured (210). A non-fibrous silicate fire resistant material (190, 230) is introduced by: (i) admixing the fire resistant material with the resin composition, and/or (ii) applying the fire resistant material to an outer surface of the pre-preg or an outer surface of the skin of the uncured artifact, and/or (iii) applying the fire resistant material to an outer surface of the skin of the cured artifact. The invention extends to a flame-proofed artifact (15).

  • Patent number: 8242035
    Abstract: A textile web material impregnated with a mixture that contains at least a prepolymer prepolymerized from a starting material of one or more bifunctional or polyfunctional organic cyanates and from a starting material of one or more bifunctional or polyfunctional aromatic alcohols, wherein the one or more bifunctional or polyfunctional organic cyanates and the one or more bifunctional or polyfunctional aromatic alcohols are present in weight ratios ensuring a molar ratio of the OCN groups to the OH groups between 95:5 and 70:30 prior to prepolymerization. The mixture further contains one or more fillers.

  • Publication number: 20110284689
    Abstract: The present invention relates to an aircraft cabin panel for sound reduction in an interior space. The invention in particular also relates to an aircraft comprising an interior lining with sound-absorbing and sound-reducing panels. In order to provide a panel that is optimized in terms of the design space required by it and in terms of its weight, for use in aircraft, which panel provides improved sound reduction and sound absorption characteristics, an aircraft cabin panel for sound reduction in an interior space is provided, which aircraft cabin panel in at least one region comprises a sandwich construction with a core layer, a first covering layer and a second covering layer. The core layer comprises sound absorbing open-pore core material. The first and the second covering layer are connected to the core layer in a planar fashion. The first covering layer is arranged towards the sound waves to be absorbed and the second covering layer is arranged opposite the first covering layer.
