Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of composite material structure manufacturing, in particular to a square composite material cylinder curing pressurizing device. BACKGROUND

[0002] Resin-based composite material products need to be fully pressurized during the curing process. The existing curing pressurizing technology mainly includes gas pressurization, wrapped cloth bag pressurization, rigid plate pressurization, etc. Among them, the gas pressurization is generally carried out in a gas pressure kettle, and there is no special requirement for the shape of the product, but it is only suitable for dry-winding products; the wrapped cloth bag pressurization and the rigid plate pressurization are suitable for wet-winding products, and in practical application, the wrapped cloth bag pressurization is generally suitable for central-symmetrical products, and the rigid plate pressurization is often applied to the pressurization of laminated plates.

[0003] When the wrapped cloth bag pressurization method is used for curing the composite material cylinder with a square cross section, it is found that the four surfaces of the square composite material cylinder are all convex. The reason is that the product with a square cross section is a flexible plate beam with two edges fixed on any surface, and the gas pressure formed by the volatilization of the composite material acts on the flexible cloth bag plate beam during the curing process, forming an outward deflection and presenting a convex phenomenon. In summary, the existing wrapped cloth bag pressurization method is not suitable for the curing and pressurization of the square composite material cylinder, and a new solution needs to be explored.
