Use of inorganic particles to produce a barrier layer on aircraft components

Abstract

The present invention relates to a plastics material component for an aircraft, comprising (i) a substrate, which comprises one or more thermosetting plastics materials, and (ii) one or more layers which are applied to the substrate, at least one layer S 1 comprising mica.

1 . A plastics material component for an aircraft, comprising
 (i) a substrate, comprising one or more thermosetting plastics materials, and   (ii) one or more layers applied to the substrate, at least one layer comprising mica.   
     
     
         2 . The plastics material component according to  claim 1 , wherein the one or more thermosetting plastics materials is selected from an epoxy resin, a phenolic resin, a polyester resin, a triazine resin, a biopolymer resin formed from renewable organic starting materials or a mixture of these resins. 
     
     
         3 . The plastics material component according to  claim 1 , wherein the substrate is a composite. 
     
     
         4 . The plastics material component according to  claim 3 , wherein the reinforcing fibres of the composite are selected from glass fibres, carbon fibres, natural fibres, aramid fibres, polyethylene fibres or combinations of these fibres. 
     
     
         5 . The plastics material component according to  claim 1 , wherein the mica is selected from phlogopite, muscovite, fluorophlogopite, micanite or a mixture thereof. 
     
     
         6 . The plastics material component according to  claim 1 , wherein the mica content of the layer is at least 80% by weight. 
     
     
         7 . The plastics material component according to  claim 1 , wherein the mica is provided in an amount of less than 50 g per m 2  substrate surface. 
     
     
         8 . A method for producing the plastics material component according to  claim 1 , comprising providing a substrate, comprising at least one thermosetting plastics material or one polymer which is crosslinked to form a thermosetting plastics material, and applying one or more layers to the substrate, at least one layer comprising mica. 
     
     
         9 . A method according to  claim 8 , wherein the mica-containing layer is applied directly to the substrate and the application is carried out before and/or during the curing of the thermosetting plastics material. 
     
     
         10 . The method according to  claim 8 , wherein the substrate is in the form of a prepreg. 
     
     
         11 . The method according to  claim 8 , wherein the substrate is provided in the form of a prepreg which already comprises a mica-containing layer. 
     
     
         12 . The method according to  claim 8 , wherein the mica-containing layer is applied to the substrate by an electrostatic application method. 
     
     
         13 . The method according to  claim 12 , wherein a mica layer is applied to a foil and held on the foil surface by electrostatic interactions, and the mica layer provided on the foil is subsequently transferred to the substrate to form the mica-containing layer. 
     
     
         14 . (canceled)
