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) Put the high-strength glass fiber in an oven at 80℃ for 4 hours for drying treatment;

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

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

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

[0043] 5) The aluminum alloy inner liner is used as the inner lining. Because 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;

Embodiment 2

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

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

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

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

[0072] 4) Pour the stirred resin matrix into the glue tank, and the dried glass fiber infiltrates the resin from the glue tank. The resin needs to be kept in a water bath at 45°C to ensure a good infiltration effect under low viscosity;

[0073] 5) The aluminum alloy inner liner is used as the inner lining. Because 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;

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 composite material high-pressure gas cylinders, in particular to a glass fiber full-wound aluminum liner composite gas cylinder and a manufacturing process thereof. Background technique [0002] At present, the gas cylinders used in the market can be divided into four categories according to the international standard ISO 11119 "Composite Structure Gas Cylinder Specifications and Test Methods", mainly including Type I metal cylinders and Type II metal liner circumferentially wound composite gas Cylinder, type III metal liner fully wound composite gas cylinder and type IV plastic liner fully wound composite gas cylinder. [0003] Type I metal gas cylinders are low in price, but have low safety, lack of longitudinal strength, medium quality, and low life. If the steel high-pressure gas cylinder encounters an accident, its rupture is a sudden fragmentation mode, and the fragments it produces are very harmful to people. [00...
