The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.
With the development of pressure vessel technology, the pressure vessel gradually changes from a metal material structure to a composite material structure. Mainly comprises I type (all-metal gas cylinder), II type (metal liner straight cylinder section winding fiber), III type (metal liner full winding fiber), IV type (plastic liner full winding fiber) and the like. At present, the I type and the II type influence the application range of the I type and the II type due to large weight and low pressure bearing. The type III and type IV gas cylinders have high pressure bearing capacity and light weight, and the preparation technology is gradually mature and is in a vigorous popularization stage.
In the preparation materials of the III type and IV type gas cylinders, the inner container mainly adopts aluminum alloy, polyamide, polyethylene and the like. The winding reinforcing fiber mainly comprises carbon fiber, glass fiber, basalt fiber and the like, and the resin matrix mainly comprises epoxy resin, unsaturated polyester, polyurethane and the like.
Among them, carbon fiber is excellent in performance, but is high in price, so that the wide-range use of the carbon fiber is influenced; the glass fiber has low strength, high density and low cost, and is generally used for products with low requirements. The basalt fiber has strength slightly lower than that of carbon fiber but higher than that of common glass fiber and aramid fiber, has good corrosion resistance, thermal stability and moderate price, and is an ideal reinforcing material.
