Description

Technical Field

[0001] The invention relates to the technical field of composite material structure forming, and more specifically to a composite material T-shaped reinforced wall panel co-curing integral forming method. Background Art

[0002] At present, composite materials are increasingly used in the field of civil aviation. Composite materials have been used in secondary load-bearing structures such as fairings, leading and trailing edges, spoilers, etc., to main load-bearing structures such as wings and fuselages. The proportion of composite materials is constantly expanding, making the structure lighter and reducing manufacturing costs at the same time has become a hot topic in the research of composite parts.

[0003] Composite T-shaped stiffened wall panels are composed of skins and long spars, and are mainly used in structures such as wings, rudders, and fuselages. The tolerance of composite parts is affected by factors such as forming methods and processes, mold materials and structures, and mold accuracy.

[0004] The traditional molding process uses many molds, and the positioning tooling is complex. The mold and the composite material are hard-fitted, and the fitting clearance is uncontrollable, resulting in uneven pressure transmission, which is easy to cause defects such as R-angle delamination and debonding, resulting in poor molding quality of the final composite component and increasing the mold manufacturing cost. When the positioning tooling is cured together with the parts, the thermal conductivity is inconsistent, resulting in uneven heat transfer in different parts of the parts, which increases the deformation of the parts. In the co-bonding and secondary bonding process steps, the skin or the long stringer must be cured first, and then the two are bonded, which will increase certain manufacturing costs. The tolerances of composite reinforced wall panels mainly involve the tolerance of the long stringer axis, the wall thickness tolerance, and the warping tolerance after forming. During the curing process, the wall thickness tolerance deviation is large due to the inconsistency between the thermal expansion coefficient of the mold and the composite material.

[0005] In summary, composite components formed by traditional forming process methods have problems such as poor forming quality, low forming precision and high forming cost. Summary of the invention

The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments:

[0050] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of the present invention provides a method for co-curing and integrally forming a composite material T-shaped stiffened wall panel, comprising the following steps:

[0051] The skin prepreg is laid on the skin forming mold 1 to form a skin preform 2; specifically, the profile of the skin forming mold 1 is completely consistent with the outer profile of the skin to be finally formed to ensure the quality of the skin outer surface. According to the size of the part, the skin forming mold 1 is a frame mold or a flat mold. Generally, large molds are frame molds, and their outer shapes are supported by the frame so that they do not deform during use and forming. The skin can be laid by an automatic tape laying machine, an automatic wire laying machine or manually according to the outer shape to form a skin preform 2.

[0052] Laying T-shaped bar prepreg on the T-shaped bar mold 10 to form a T-shaped bar preform 3;

[0053] Positioning and installing the T-shaped rib preform 3 on the skin preform 2, and removing the T-shaped rib mold to obtain a T-shaped reinforced wall panel preform;

[0054] Laying auxiliary materials on the surface of the T-shaped reinforced wall panel preform 3 for packaging;

[0055] After the packaging is completed, the dimensional pieces 4 are placed on both sides of the vertical ribs of the T-rib preform, and the two dimensional pieces 4 are clamped by the clamping piece 5 to maintain the verticality of the vertical ribs to obtain a molded component; specifically, the shape of the dimensional piece 4 is L-shaped, the vertical side of the L-shaped is consistent with the shape of one side of the vertical rib of the T-rib preform 3, the height is 0-5mm higher than the height of the vertical rib, and the width of the bottom edge is 10mm-1 / 2 of the distance between the T-shaped vertical ribs. The material constituting the dimensional piece is determined according to the curing process of the molding, and materials such as aluminum, composite materials, iron or stainless steel can be selected. Specifically, the clamping piece 5 can be a quick clamping piece or a mechanical clamping piece, which is determined according to the material and weight of the dimensional piece 4 used. More specifically, the dimensional piece 4 is preferably a material with a certain structural strength and a thermal conductivity coefficient that is not much different from the thermal conductivity coefficient of the composite material T-shaped reinforced wall panel to be molded.

[0056] The formed assembly is placed in an autoclave and heated and cured to obtain a composite material T-shaped reinforced wall panel 100.

[0057] In one embodiment, the clamping force f generated by the clamping member 5 satisfies f>2g / m, where g is the weight of the dimension member and m is the number of the clamping members. Specifically, by setting the clamping force generated by the clamping member 5 within this range, the dimension member 4 can be stably clamped, and excessive clamping force will not cause excessive squeezing of the ribs, thereby ensuring the forming quality of the ribs.

[0058] In one embodiment, the clamping member 5 has a clamping opening, and the width of the clamping opening is 1 / 2(2h1+h) to 5(2h1+h), wherein h1 is the thickness of the dimensional member, and h is the thickness of the rib. Figure 1 As for the U-shaped opening clamp shown, the width of its clamping opening directly affects the magnitude of the clamping force. According to different process requirements, the width of the clamping opening can be set within the above range to ensure the final forming quality of the vertical rib.

[0059] In one of the embodiments, the auxiliary materials are, from the inside to the outside, an isolation material 6, an air-conducting material 7, and a vacuum bag 8. Furthermore, a sealing strip is used to achieve a sealed connection between the vacuum bag 8 and the skin forming mold 1, thereby facilitating subsequent vacuuming. A uniform pressure plate 13 is installed in the area not covered by the T-rib on the T-rib preform 3. The uniform pressure plate 13 has certain temperature and pressure resistance characteristics and should be consistent with the thickness of the bottom of the T-rib. Rubber ribs 11 are provided at both ends of the skin preform 2 on the skin forming mold 1. The rubber ribs 11 are used to limit the two ends of the skin preform 2 to ensure the molding quality of the two ends of the skin preform 2.

[0060] In one embodiment, positioning and installing the T-shaped rib preform 3 on the skin preform 2, and removing the T-shaped rib mold to obtain a T-shaped reinforced wall panel preform includes the following steps:

The edge of the positioning fixture 9 is designed with a positioning pin for the skin forming mold 1, and is positioned on the skin forming mold 1 through two pins or positioning columns at the end, so as to realize the fixed installation of the positioning fixture 9 on the skin forming mold 1.

[0062] The positioning tool 9 is removed from the skin forming mold 1, and then the T-shaped rib mold is removed to obtain a T-shaped reinforced wall panel preform.

[0063] In one embodiment, the height of the vertical rib is 15 mm to 80 mm.
