Embodiment

[0020] A fiber-reinforced aviation interior composite film, with PVF film as the outer protective film, PET film as the matrix layer, fiber tows in the warp and weft directions as the reinforcement, and the side of the PET film layer in contact with the fiber is covered with There is an aluminum-containing epoxy resin coating; the total thickness of the fiber-reinforced aviation interior composite membrane is 35 μm; wherein, the outer protective film and one side of the base layer are bonded by an adhesive, and the fiber tow is in accordance with the first It is laid on the other side of the base layer in the form of a grid frame in the warp and weft direction, and the interlayer peel strength between the outer protective film layer and the base layer is 3 lbs / inch.

[0021] The thickness of the PVF film is 17.5 μm, the front side is an inert surface, which has self-cleaning ability, and the back side is an active surface, which can be bonded to the substrate layer with an adhe...

Abstract

A fiber-reinforced aviation interior composite film, with PVF film as the outer protective film, PET film as the matrix layer, fiber tows in the warp and weft directions as the reinforcement, and the side of the PET film layer in contact with the fiber is covered with There is an aluminum-containing epoxy resin coating; the total thickness of the fiber-reinforced aviation interior composite membrane is about 30-90 μm; among them, the outer protective film and one side of the base layer are bonded by an adhesive, and the fiber filaments The bundles are laid on the other side of the base layer in the shape of a grid frame according to the first warp and then the weft direction. The invention takes advantage of the composite structure, makes up for the shortcomings of a single PVF film, which is insufficient in mechanical strength and inert to the adhesive, and is inconvenient to use, and realizes the combination of excellent protection performance of the PVF film and enhanced self-applicability.

Description

technical field [0001] The invention belongs to the technical field of composite membrane materials, and in particular relates to a fiber-reinforced aviation interior composite membrane and a preparation method thereof. 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 material of choice for solar backplane films, and has entered the aerospace field. [0003] At present, due to its radiation resistance and chemical corrosion resistance, PVF film is also an example of choosing PVF film as the surface protection film for aircraft interior materials. Among them, the problems of cladding and mechanical properties of PVF film ar...
