Abstract

The invention relates to a co-curing process for an omega-stringer vertical and horizontal reinforcement composite integral wallboard. The process comprises the following steps: 1) preparing a composite integral tool; 2) preparing a pneumatic rubber bag and arranging a ventilating mouth on the end part of the pneumatic rubber bag; 3) laying a wallboard skin composite on a wallboard forming die; 4) laying a stringer composite on the composite integral tool and carrying out vacuum-pumping and compacting; 5) integrally turning over the composite integral tool and the composite thereon prepared in step 4), combining the composite integral tool and the composite thereon with the laid wallboard skin composite and carrying out integral packaging; 6) curing a packaged wallboard with omega-stringers and allowing the pneumatic rubber bag to be filled with high pressure gas all the time; and 7) polishing positions of the cured wallboard needing bonding of rib angle sheets. The co-curing process has simple and short processing steps, shortens a production cycle of a product, reduces errors in assembling of the tool and guarantees positioning accuracy of co-curing of the stringers.

Description

technical field

[0001] The invention relates to a co-curing process for integral wall boards of Ω long stringer vertical and horizontal reinforcement composite materials, which is used for co-curing the stringer and the skin of the wall board as a whole, and then bonding and co-curing with rib angle pieces perpendicular to the direction of the stringer Advanced manufacturing process to form the effect of vertical and horizontal reinforcement of the wall panel skin. Background technique

[0002] At present, when the component is a large curvature hyperboloid structure and the skin and the stringer are manufactured by the co-curing process, the traditional methods for ensuring the axis of the stringer include the clamping method, the metal composite mold method, and the soft rubber sleeve method. The positioning accuracy of axis combination is difficult to guarantee.

[0003] At present, the technological methods used in hollow Ω stringers in China are mainly metal mandrel me...

Embodiment Construction

[0020] Such as figure 1 As shown, the Ω long truss vertically and horizontally stiffened composite material overall wall plate is not only large in size, but also complex in shape, and the number of Ω long stringers is three. The co-curing process of the Ω long truss vertically and horizontally reinforced composite material integral wall plate includes the following steps :

[0021] 1) Preparation of overall tooling of composite materials: the overall tooling of composite materials is manufactured with tooling prepreg, and its inner profile is consistent with the overall outer profile of the Ω stringer to be processed. After the manufacturing is completed, its edges and surfaces are corrected to reach the surface smooth and smooth;

[0022] 2) The rubber airbag is made by vulcanizing the rubber layer. The outer surface of the rubber airbag is consistent with the inner surface of the long stringer to be processed, and the end is provided with a ventilator;

[0023] 3) Lay the...
