Problems solved by technology
[0002] Composite gas cylinders are widely used in the aerospace field due to their light weight, high reliability, and safe failure modes. The appearance of composite spherical gas cylinders is all composite materials except for the gas port. The connection method cannot directly install the gas cylinder on the gas cylinder installation device
[0003] Existing spherical gas cylinders made of composite materials usually adopt the installation method of wrapping structure. This method has a large additional mass and a small load-bearing capacity. It is usually only used for the installation of small-volume gas cylinders. When the strap connection structure is under the expansion force and mechanical load of the gas cylinder, it is prone to breakage and failure, and cannot provide a safe and reliable installation connection.

Embodiment Construction
[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0029] In this embodiment, carbon fiber / epoxy resin is used to connect the support ring with the spherical gas cylinder body, which solves the problem of connecting the composite material gas cylinder with the support ring. This embodiment discloses a composite material spherical gas cylinder integrated with an installation interface, such as figure 1 As shown, it includes a spherical cylinder body, a support ring 3 and a support ring fixing layer 4 .
[0030] The spherical gas cylinder body includes a titanium alloy liner 1 and a carbon fiber / epoxy resin composite layer 2. The titanium alloy liner 1 is used to seal the stored gas and provides a core mold for the integrated installation interface. The carbon fiber / epoxy resin The resin composite layer 2 is wound on the outer surface of the titanium alloy lining, and is used to bear all the internal pressu...
