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

A method for producing 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, the method 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;
• 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, and
• wherein the mica-containing layer is applied to the substrate by an electrostatic application method, and
• 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.
