Problems solved by technology

[0002] At present, the high-pressure cylinders of extrusion rocket engines all use metal cylinders. Although the molding of metal cylinders is simple and reliable, it adds a lot of negative mass. The shell of composite materials has higher specific strength and better performance. The bonding strength of metal connectors with special structures is difficult to reach the welding strength of metal gas cylinders, and it is difficult to adapt to elastic deformation during vibration
The weak point of the existing technology lies in the connection between the bottle body and the support. When the engine is working, high-frequency vibration will occur, and stress concentration will occur at the connection between the bottle body and the support, resulting in fracture of the connection between the bottle body and the support.

Embodiment Construction

[0022] pass below Figure 1 ~ Figure 2 As well as listing some optional embodiments of the present invention, the technical solutions (including preferred technical solutions) of the present invention are further described in detail. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] like figure 1 As shown, the anti-high-frequency vibration band support winding high-pressure gas cylinder forming method designed by the present invention is characterized in that it comprises the following steps:

[0024] S1. Before winding the gas cylinder, use ethyl acetate to scrub the surface of the inner liner 1. After standing for 5 minutes, apply 730 adhesive twice, with an interval of 15 minutes between each pass....

Abstract

The invention designs a forming method of a high-frequency vibration resistant high-pressure gas cylinder wound with a support, which is characterized by comprising the following steps: S1, cleaning the surface of a lining, and brushing an adhesive; s2, longitudinally winding, annularly winding and reinforcing the winding layer according to the thickness of the composite layer required by the design, and then pre-curing; s3, bonding of the support is completed; s4, outer reinforcement and winding of the support are completed; and S5, the wound gas cylinder is subjected to final curing. According to the gas cylinder connecting structure, the negative mass of the extrusion type rocket engine high-pressure gas cylinder is reduced, and the reliability of the gas cylinder connecting structure is improved; the winding core mold is simple in principle, easy to process, detachable and low in cost; and the prepared composite material has the advantages of high reliability, good loading capacity and the like.

Description

technical field [0001] The invention belongs to the technical field of extrusion rocket engine high-pressure gas cylinders, and in particular relates to a high-frequency vibration-resistant belt support winding high-pressure gas cylinder molding method of a carbon fiber reinforced epoxy resin matrix system Background technique [0002] At present, the high-pressure cylinders of extrusion rocket engines all use metal cylinders. Although the molding of metal cylinders is simple and reliable, it adds a lot of negative mass. The shell of composite materials has higher specific strength and better performance. The bonding strength of metal connectors with special structures is difficult to reach the welding strength of metal gas cylinders, and it is difficult to adapt to elastic deformation during vibration. The weak point of the prior art lies in the connection between the bottle body and the support. When the engine is working, high-frequency vibrations will be generated, and s...
