- a fiber reinforced composite material for example, carbon fiber reinforced plastic; CFRP
- CFRP carbon fiber reinforced plastic
- the skin may be fitted with stringers to increase its strength.
- the skin to which the stringer is attached is hereinafter referred to as a reinforcing structure.
- Fiber reinforced composite materials may be used as stringers as well as skins.
- a cured stringer is placed over the uncured skin via an adhesive.

- FIG. 8 is a schematic cross-sectional view showing a reinforcing structure in the manufacturing process.
- FIG. 1 is a schematic cross-sectional view showing a main wing member 20 to which a reinforcing structure 1 according to a first embodiment of the present invention is applied.
- the main wing member 20 has a pair of skins 2 (2-1, 2-2) and a spar 16.
- the spar 16 is disposed between the skin 2-1 and the skin 2-2.
- a fuel tank 15 is formed by an area surrounded by the skin 2-1, the skin 2-2, and the spar 16.
- the stringer 3 is joined to the skin 2, and the reinforcement structure 1 is comprised by this. That is, the reinforcing structure 1 includes the skin 2 and the stringer 3.
- fiber reinforced composites are used respectively.
- a material in which a fiber component and a thermosetting resin component are combined is used as the fiber reinforced composite material.
- a carbon fiber reinforced plastic material is used as the fiber reinforced composite material.
- edge glow may occur as described above. If the exposed fiber surface is present in the fuel tank 15, the edge glow may ignite the fuel. Therefore, for the stringer 3 disposed in the fuel tank 15, the prevention of edge glow is particularly required.
- FIG. 2 is a schematic cross-sectional view showing the reinforcing structure 1. As described above, the reinforcing structure 1 has the skin 2 and the stringer 3.
- the stringer 3 has a plate portion 4.
- the plate portion 4 has an adhesive surface 5 and an end surface 6 and is joined to the skin 2 at the adhesive surface 5.
- the end face 6 is a portion processed after curing of the stringer 3 and is a fiber exposed surface.
- the stringer 3 is provided with a protective layer 8 so as to cover the end face 6.
- the provision of the protective layer 8 protects the exposed fiber component on the fiber exposed surface. This prevents edge glow discharge.
- FIG. 3 is a flowchart showing a method of manufacturing the reinforcing structure 1.
- Step S1 Preparation of Stringer
- the stringer 3 contains a fiber component and a resin component, and the fiber component is impregnated with the resin component.
- the surface of the stringer 3 is covered with a resin component.
- the hardened stringer 3 is processed for the purpose of adjusting the size and the like.
- the end face 6 is processed. Thereby, the end face 6 becomes a fiber exposed surface.
- Step S2 Arrangement of Conductive Protective Material
- the conductive protective material 9 is applied (arranged) to the stringer 3.
- the conductive protective material 9 is attached so as to cover at least a part of the end face 6.
- a composite material in which an uncured thermosetting resin component 13 and a conductive fiber component 14 are combined is preferably used.
- a carbon fiber component is used as the fiber component 14. That is, an uncured carbon fiber reinforced plastic material is used as the conductive protective material 9.
- FIG. 5 is a schematic cross-sectional view showing the configuration of the end face 6.
- the conductive protection material 9 is attached to only a part of the end face 6 so that the conductive protection material 9 and the adhesive surface 5 are separated.
- the conductive protective material 9 is pasted so that the coated area 12-1 and the exposed area 12-2 are formed on the end face 6.
- the covering area 12-1 is an area covered by the conductive protection material 9.
- the exposed area 12-2 is an area where the end face 6 is exposed.
- the exposed area 12-2 is provided between the covered area 12-1 and the adhesive surface 5.
- the exposed area 12-2 is set to an area covered with the adhesive 10 which has flowed out as described later.
- Step S3 Placing Stringer on Skin Subsequently, as shown in FIG. 6, the stringer 3 is placed on the uncured skin 2. Specifically, first, the adhesive 10 is applied to the adhesive surface 5. The stringer 3 is then placed on the skin 2 so that the adhesive surface 5 adheres to the skin 2.
- thermosetting resin sheet is suitably used as the adhesive 10.
- Step S4 Curing Next, the skin 2 and the conductive protective material 9 are simultaneously cured. That is, the respective resin components of the skin 2 and the conductive protection material 9 are simultaneously cured. The skin 2 and the conductive protection material 9 are cured, for example, by heat and pressure. At this time, the adhesive 10 is also cured. Thereby, the stringer 3 is integrally bonded to the skin 2 to obtain the reinforcing structure 1.
- the adhesive 10 flows out of the end of the plate portion 4.
- the exposed area 12-2 at the end face 6 is covered by the adhesive 10 that has flowed out. That is, the end face 6 is covered with the conductive protective material 9 and the adhesive 10, and the protective layer 8 is formed.
- the outflow of the adhesive 10 can be a hindrance to the operation in the later process, if normal, but in the present embodiment, the outflow is used reversely.
- the reinforcing structure 1 according to the present embodiment is obtained by the method described above.
- the coated area 12-1 on the fiber exposed surface (end surface 6) is protected by the conductive protective material 9. Therefore, even when electrical energy is applied to the reinforcing structure 1, the electrical energy is released to the conductive protective material 9 before sparking.
- the exposed area 12-2 is insulated by the adhesive 10. Thus, edge glow is prevented.
- the curing of the conductive protective material 9 and the curing of the skin 2 are performed in the same step. It is possible to seal the fiber exposed surface (end surface 6) without newly adding a process for curing the conductive protective material 9. That is, a reinforcing structure capable of preventing edge glow can be obtained without increasing the number of manufacturing steps.
- step S2 the conductive protective material 9 is attached to only a part of the end face 6 so that the conductive protective material 9 and the bonding surface 5 are separated. Thereby, the fiber component contained in the conductive protection material 9 is prevented from being mixed between the adhesive surface 5 and the skin 2.
- the strength of the reinforcing structure 1 may be reduced by the incorporation of the fiber component.
- the mixing of the fiber component is prevented, the reduction in the strength of the reinforcing structure 1 is prevented.
- Carbon fiber reinforced plastic materials have high strength. Therefore, even if carbon fiber which is a fiber component is mixed between the bonding surface 5 and the skin 2, the strength of the reinforcing structure 1 is not reduced. From this point of view, a carbon fiber reinforced plastic material is preferably used as the conductive protective material 9.
- the conductive protective material 9 it is not necessary to use a carbon fiber reinforced plastic material as the conductive protective material 9 as long as it is a composite material in which the thermosetting resin component 13 and the conductive fiber component 14 are combined. It is also possible to use materials. In particular, as compared with the case where the fiber exposed surface is covered with an insulating material, in the present embodiment, since the conductive protective material 9 is used, it is possible to expand the choice of materials.
- the “conductive fiber component 14” also includes a semiconductor.
- the fiber component 14 contained in the conductive protective material 9 it is also possible to use a SiC fiber as a semiconductor other than the carbon fiber.
- the reinforcing structure 1 applied to the fuel tank 15 of the main wing member 20 has been described.
- the reinforcing structure 1 does not necessarily have to be used for the fuel tank 15, and can be suitably used for other applications if it is necessary to prevent edge glow.
- the resin component contained in the skin 2, the resin component contained in the stringer 3, the resin component 13 contained in the conductive protective material 9, and the adhesive 10 are preferably the same component. By making these components identical, the physical properties of the respective parts become close, and the overall strength of the reinforcing structure 1 can be enhanced.
- these resin components for example, epoxy resins and acrylic resins can be used.
- the stringer 3 is disposed on the skin 2.
- the conductive protection material 9 may be applied to the stringer 3 after the stringer 3 is disposed on the skin 2. Even in this case, it is possible to cure the skin 2 and the conductive protective material 9 in the same process.
- step S2 the conductive protection material 9 is applied so as to cover the entire end face 6. That is, the conductive protective material 9 is also applied to a part of the bonding surface 5. Thereafter, the adhesive 10 is applied to the adhesive surface 5, and the stringer 3 is placed on the skin 2 (step S3). Thereafter, the skin 2 and the conductive protection material 9 are cured (step S4).
- the fiber exposed surface (end surface 6) is completely covered with the conductive protection material 9, it becomes possible to prevent the edge glow more reliably.
- the conductive protection material 9 is mixed in a part between the skin 2 and the plate portion 4.
- an insulating material such as glass fiber
- the strength of the reinforcing structure 1 may be reduced.
- a high strength material such as a carbon fiber reinforced plastic material
- the strength of the reinforcing structure 1 is obtained even if the conductive protective material 9 is mixed between the skin 2 and the plate portion 4. Does not decline.

Abstract
Description
図1は、本発明の第1実施形態に係る補強構造体1が適用された主翼部材20を示す概略断面図である。図1に示されるように、主翼部材20は、一対のスキン2(2-1、2-2)、及びスパー16を有している。スパー16は、スキン2-1とスキン2-2との間に配置されている。スキン2-1、スキン2-2、及びスパー16により囲まれた領域により、燃料タンク15が形成されている。また、スキン2には、ストリンガー3が接合されており、これによって補強構造体1が構成されている。すなわち、補強構造体1は、スキン2及びストリンガー3を含んでいる。
まず、硬化済みのストリンガー3が準備される。ストリンガー3は、既述のように、繊維成分と樹脂成分とを含んでおり、繊維成分は樹脂成分に含浸されている。ストリンガー3の表面は樹脂成分に覆われている。硬化済みのストリンガー3は、寸法の調整などを目的として、加工される。本実施形態では、端面6が加工される。これにより、端面6が繊維露出面になる。
次いで、図4に示されるように、ストリンガー3に、導電性保護材9が適用(配置)される。導電性保護材9は、端面6の少なくとも一部を覆うように、貼り付けられる。
続いて、図6に示されるように、ストリンガー3が未硬化のスキン2上に配置される。具体的には、まず、接着面5に接着剤10が適用される。その後、接着面5がスキン2に接着するように、ストリンガー3がスキン2上に配置させられる。
次いで、スキン2及び導電性保護材9が同時に硬化させられる。すなわち、スキン2及び導電性保護材9のそれぞれの樹脂成分が、同時に硬化させられる。スキン2及び導電性保護材9は、例えば、熱及び圧力により、硬化させられる。この際、接着剤10も硬化させられる。これにより、ストリンガー3がスキン2に一体に結合し、補強構造体1が得られる。
続いて、第2の実施形態について説明する。本実施形態では、第1の実施形態と比較し、導電性保護材9の適用位置が変更されている。その他の点については、第1の実施形態と同様の構成を採用することができるので、詳細な説明は省略する。
