Integral molding method for vertical-rib composite material stiffened wallboard through autoclave

Abstract

The invention relates to an integral molding method for a vertical-rib composite material stiffened wallboard through an autoclave and belongs to the technical filed of composite material molding. Theintegral molding method for the vertical-rib composite material stiffened wallboard through the autoclave includes the steps of soft mold manufacturing, product blanking, and product manufacturing. Askin molding mold is paved with a composite material faceplate, is placed into the autoclave and is taken out of the autoclave after solidified molding. The composite material faceplate is paved witha skin. All webs, middle flange strips and radius fillers are laid on respective tools. The middle flange strips and the radius fillers are demolded after laying is finished. U-shaped groove webs, the middle flange strips, the radius fillers, and bilateral L-shaped webs are placed on a positioning mold and combined and then placed into the autoclave so as to be preformed into a long purlin: the skin with the composite faceplate and the skin molding mold are together placed into the autoclave to be preformed; the long purlin and the skin are taken out of the autoclave; the long purlin is demolded and is positioned with the skin in a combination mode; a stripping cloth, an isolating film, the soft mold, and a ventilated felt are positioned on the long purlin; and the long purlin is encapsulated with a vacuum bag to enter the autoclave to be solidified; and after solidified well, the long purlin is taken out of the autoclave, and is demolded and milled to form a product. The integral molding method is used for manufacturing the vertical-rib composite material stiffened wallboard.

Description

technical field [0001] The invention belongs to the technical field of composite material molding, and in particular relates to an integral molding method of a composite material reinforced wallboard autoclave with vertical ribs. Background technique [0002] The utility model relates to a composite material reinforced wall plate with vertical ribs, which is mainly used for raising and lowering rudder surfaces. The elevator is the controllable part of the horizontal tail of the aircraft. Its main function is to control the pitching movement of the aircraft. When the aircraft needs to fly upwards, the pilot will control the elevator to deflect upward. At this time, the aerodynamic force on the elevator is downward, and the aircraft A head-up moment is generated, and the aircraft is raised up. Conversely, if the pilot manipulates the elevator to deflect downward, the aircraft will bow under the action of aerodynamic moment. The strength of this pitching motion is determined ...
