Problems solved by technology

[0009] The invention provides a glass fiber fully wound aluminum liner composite gas cylinder and its manufacturing process. The type III glass fiber fully wound aluminum liner composite gas cylinder developed by the technology of "layered processing and multiple curing" overcomes the The raw materials of carbon fiber full-wound aluminum liner cylinders are monopolized abroad, the price is high, and the molding process is complicated. The glass fiber is dried, the resin is heated and defoamed, and the prepared resin is treated with a water bath. The three processes ensure that the resin infiltrates the fibers to improve the fiber strength. Compared with the production process of carbon fiber full-wound aluminum liner cylinders, the use of new glass fibers saves the insulating layer on the surface of the aluminum liner and the surface of the cylinder. Protective layer, which simplifies the molding process and improves efficiency

Embodiment 1

[0039] 1) Dry the high-strength glass fiber in an oven at 80°C for 4 hours;

[0040] 2) Use a 20 kg metal bucket to open the epoxy resin matrix, and bake it in an oven at 40°C for 2 hours for defoaming treatment;

[0041] 3) Take the epoxy resin (Dow Chemical der331) that has undergone defoaming treatment and mix it with the curing agent (Italy Pauline MMHPA), and stir it for 10 minutes at the speed of 90r / min in a pneumatic mixer;

[0042] 4) Pour the stirred resin matrix into the glue tank, and the dried glass fiber soaks the resin from the glue tank. The resin needs to be kept warm in a 40°C water bath to ensure a good wetting effect under low viscosity;

[0043] 5) The aluminum alloy liner is used as the inner lining. Since the glass fiber reinforced resin matrix composite material is an insulating material, the glass fiber reinforced resin matrix composite material is directly wound after the process top block is installed on the winding machine;

[0044] 6) The winding ...

Embodiment 2

[0054] 1) Dry the high-strength glass fiber in an oven at 75°C for 8 hours;

[0055] 2) Use a 20 kg metal bucket to open the epoxy resin matrix, and bake it in an oven at 35°C for 4 hours for defoaming treatment;

[0056] 3) Take the epoxy resin (Dow Chemical der331) that has undergone defoaming treatment and mix it with the curing agent (Italy Pauline MMHPA), and stir it for 10 minutes at the speed of 90r / min in a pneumatic mixer;

[0057] 4) Pour the stirred resin matrix into the glue tank, and the dried glass fiber soaks the resin from the glue tank. The resin needs to be kept warm in a 35°C water bath to ensure a good wetting effect under low viscosity;

Abstract

The invention discloses a glass fiber all-winding aluminum liner composite cylinder and a manufacturing process thereof. The process comprises the following steps of: (1) carrying out drying treatment on the glass fiber, defoaming epoxy resin matrix, then uniformly mixing with a curing agent to obtain resin matrix, and carrying out water bath thermal insulation on the resin matrix; (2) soaking the glass fiber subjected to the drying treatment in the resin matrix of water bath thermal insulation to obtain a glass fiber reinforced resin matrix composite material; (3) winding the glass fiber reinforced resin matrix composite material for 2-5 layers on the surface of the aluminum alloy liner, and defoaming, curing and carrying out surface polishing after winding one layer; and (4) curing and carrying out water self-compacting treatment after winding the final layer. Compared with the production technology of a carbon fiber all-winding aluminum liner gas cylinder, the process has the advantages of saving the insulating layer of aluminum liner surface and the protective layer of the air cylinder surface, so that the forming process is simplified, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of high-pressure gas cylinders made of composite materials, in particular to a composite gas cylinder with a glass fiber fully wound aluminum liner and a manufacturing process thereof. Background technique [0002] At present, the gas cylinders used in the market can be divided into four types according to the international standard ISO11119 "Composite Structure Gas Cylinder Specifications and Test Methods", mainly including Type I metal gas cylinders and Type II metal liner circumferentially wound composite gas cylinders , Type III fully wound composite gas cylinder with metal liner and fully wound composite gas cylinder with type IV plastic liner. [0003] Type I metal gas cylinders are cheap, but have low safety, lack of longitudinal strength, medium quality and low service life. If the steel high-pressure gas cylinder encounters an accident, its rupture is a sudden fragmentation mode, and the fragments produced b...
