Abstract

The invention provides a process method for co-bonding forming of composite I-shaped reinforced wallboards of planes. The method comprises the steps of skin laying and pasting, process cover plate placing, stringer preparing, stringer pre-assembling, stringer and skin combining, stringer mandrel filling, vacuum bag packaging, curing and demolding, wherein in the process cover plate placing step, aprocess cover plate is placed on a laid and pasted skin, and the process cover plate is provided with a plurality of stringer reservation slots for placing I-shaped stringers.

Description

technical field [0001] The invention belongs to the field of composite material manufacturing, and in particular relates to a process method for co-gluing forming of I-shaped reinforced wall panels of aircraft composite materials. Background technique [0002] The composite material reinforced panel structure is composed of skin and I-shaped long trusses, which can obtain greater structural rigidity and buckling resistance, and improve structural efficiency. The co-gluing process is used to manufacture composite material reinforced wall panels, and the I-shaped stringer is bonded to the skin through the adhesive film, which simplifies the traditional riveting connection method, reduces the number of fasteners, and has better performance. Great reduction of assembly cost and weight reduction effect. Compared with the process of co-curing, co-gluing can not only reduce the difficulty of mold design and manufacturing, but also reduce the risk of overall scrapping of parts; com...
