Abstract

The invention discloses a method for preparing a composite material pressure container with a PbSn alloy lining by plasma spray, belonging to the material field. By the invention, the problem that the conventional composite material pressure containers have excessive weight is solved. The method comprises the following steps of: firstly, preparing a carbon fiber enwinding composite material enwinding layer provided with epoxy resin by immersion on a core module according with the pressure container in shape; secondly, preparing a resin transition layer doped with metal powders on the inner wall of the carbon fiber enwinding composite material enwinding layer; thirdly, curing the prepared fiber enwinding layer and the resin transition layer doped with the metal powders; and fourthly, preparing the lining layer of the pressure container on the inner wall of the cured resin transition layer in a plasma spray mode. The method is used for preparing light pressure containers.

Description

technical field [0001] The invention relates to a method for preparing a PbSn alloy-lined composite material pressure vessel by plasma spraying, and belongs to the field of materials. Background technique [0002] Composite pressure vessels are an important part of space system engines, and their purpose is to solve the problem of gas fuel carrying in space vehicles. Because the composite material pressure vessel not only takes into account the good processability, air tightness, corrosion resistance, high strength and high toughness of the metal lining, but also combines the light weight, good safety and good designability of the composite material. Advantages, compared with pure all-metal pressure vessels, composite material pressure vessels have significant characteristics such as light structure weight, flexible selection of external dimensions, high safety and reliability, corrosion resistance, and fatigue resistance. The performance factor of the container is high, wh...
