Abstract

The invention discloses a light-weight aviation interior composite film. The light-weight aviation interior composite film is formed by successively compounding three layers, namely a fluorine-containing coating as a surface layer, a PET aluminum plating thin film or a PI aluminum plating thin film as a substrate layer and a fiber fabric as a reinforcement; the total thickness of the light-weight aviation interior composite film is roughly 24 to 50 mu m, wherein the fibers are paved on the aluminum plating surface of the substrate layer in a grid shape, and the fluorine-containing coating as the surface layer directly coats the surface of the substrate layer. The light-weight aviation interior composite film disclosed by the invention exerts the advantages of a composite structure and has the characteristics of good weather-resisting property and excellent corrosion resistance and fouling resistance of the fluorine-containing layer as well as high strength of the fabric.

Description

technical field [0001] The invention relates to the technical field of composite membrane materials, in particular to a lightweight aviation interior composite membrane. Background technique [0002] Due to the stability of the C-F bond in the molecular structure, the fluorine-containing film has special surface properties such as extraordinary weather resistance, durability, good non-adhesion, low surface tension, low friction, water repellency, and oil repellency. As well as electrical properties such as high insulation and low electrolytic constant, it has become the first choice material for solar protective films, and it is entering the aerospace field, and it is the first choice for aircraft interior surface protective films. [0003] At present, compared with PVF film and PVDF film, fluorine-coated composite film also has the characteristics of radiation resistance and chemical corrosion resistance, and is mostly used to protect objects and materials. However, the fi...
