Description

Technical Field

[0001] The invention relates to the field of vacuum testing technology, in particular to a vacuum container for simulating space environment of aerospace equipment. Background Art

[0002] A hot press vacuum tank is a kind of equipment used for material processing, especially suitable for the molding and curing process of composite materials. It promotes the flow and curing of resin by combining high temperature and vacuum environment, thereby improving the strength and density of materials. During the manufacturing process of aerospace equipment and materials, it is necessary to simulate the space environment for testing. Therefore, hot press vacuum equipment is needed to simulate high temperature and high pressure environment for manufacturing composite parts of aircraft and spacecraft.

[0003] By extracting the air in the tank, reducing bubbles and impurities, the quality of the finished material is improved. The equipment has a built-in heater to maintain a preset temperature so that the resin flows better at high temperatures and applies additional pressure to further enhance the structural properties of the composite material.

[0004] The existing technology often adopts a static placement method for the material testing process, which makes the material pressurization or heating environment single. If there is a local pressure or temperature imbalance, it is difficult to adjust during the processing. During the material curing process, volatile gas may be generated. After the test is completed, the volatile gas is discharged slowly;

[0005] Existing equipment often lacks real-time monitoring and feedback mechanisms for internal temperature and pressure, which may result in the inability to make timely adjustments or take measures when abnormal situations occur during the test process. When abnormalities occur, adjustments often rely on manual intervention, which can easily lead to greater risks and may cause unreliable test data or damage to equipment. Summary of the invention
