Production technology of carbon fiber composite aircraft

Abstract

The invention discloses a production technology of a carbon fiber composite aircraft. The production technology comprises the steps that a product drawing is determined; a latex airbag inner container and an EPS central spindle are designed according to the drawing; an aircraft manufacturing mold and an EPS central spindle manufacturing mold are designed and manufactured; the EPS central spindle and the latex airbag inner container are manufactured; forming materials are prepared; carbon yarn fabric is cut according to an arranging and stacking sheet; the shape of the aircraft is rolled on the surface of the latex airbag inner container in advance; the latex airbag inner container is placed in an aircraft forming mold, the mold is closed and fed to a furnace stage to be heated, meanwhile, air pressure is provided for the interior of the latex airbag inner container through a charging port, a product is fed to be cooed after being formed, finally, the mold is opened, and the formed aircraft is taken out; trimming and cutting are carried out; other components which cannot be integrally formed are bonded and fixed to the aircraft; and polishing and puttying are carried out on the surface of the aircraft. The latex airbag inner container is inflated with high-pressure air for pressurization, extrusion forming is achieved, and the finished carbon fiber composite aircraft with steps on the inner wall of a shell can be obtained.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber composite material aircraft forming, and in particular relates to a production process of wind pressure forming carbon fiber composite material aircraft. Background technique [0002] Conventional carbon fiber composite aircraft with uniform wall thickness, no steps on the inner wall, and undercuts can generally be formed by compression molding or nylon airbag air pressure molding. The compression molding process uses the forming furnace to pressurize and heat the mold, and pressurizes and heats the product to be formed through the mold to realize the molding of the product, which includes drawing confirmation, mold design and manufacturing, material preparation, yarn cutting, preforming, forming, Processing steps such as trimming and cutting, gluing, fine soil filling, and painting. However, this molding process is not suitable for the production of products with uneven wall thickness and in...
