Multi-layer tubular structure for aerospace aerodynamic loading mechanism and application of multi-layer tubular structure

The invention discloses a multi-layer tubular structure for an aerospace aerodynamic loading mechanism and application of the multi-layer tubular structure. The multilayer tubular structure includes: an outer layer comprising a first polymeric material that prevents adhesion of an inner layer material; an inner layer comprising one to two layers of a second polymer material; the first polymer material is polyimide; the second polymer material is selected from fluorine-containing resin or a combination of fluorine-containing resin and nylon. The polyimide layer is additionally arranged on the outer side of the fluorine-containing resin and the nylon through a simple structural design, so that on the basis of ensuring the excellent physical and chemical properties of the original material, the gas transmission pipe is further enabled to better adapt to the aerospace environment, and the conditions that the internal pressure resistance of the gas transmission pipe is reduced and the gas transmission pipe adheres
