Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a composite blade and a method of forming the same for ensuring adhesion quality and improving appearance quality and external accuracy.
[0002]
[Prior art]
In the conventional composite adhesive box structure, there are structures in which the member dimensions (plate thickness and overall height) are small and the upper and lower external members and internal members such as girders are bonded and integrated. However, there are few applications for large structures such as the main wing of a passenger aircraft.
[0003]
The conventional composite adhesive box structure uses the inner surface side of the outer surface member as the jig surface, and is manufactured using a hard jig considering that it can be removed after curing, thereby bonding the outer surface member and the inner member. Many methods have been taken to give priority to the joint strength of the part, but in this case, it is difficult to improve the appearance quality of the outer surface member.
[0004]
In the conventional composite material adhesive box structure, when obtaining the outer surface quality of the outer surface member, a technique is adopted in which the outer surface side of the outer surface member is a jig surface. In order to ensure the adhesive strength of the bonding part, gap filling material is packed between the surface member and the internal member, but it takes a lot of time to check the thickness of the gap packing material, and the cost Has been rising.
[0005]
As a conventional composite blade 1, as shown in FIG. 7, an adhesive 5 is disposed between the upper and lower outer plates 2 and 3 of the composite material and the inner surfaces of the upper and lower outer plates 2 and 3 disposed between the upper and lower outer plates 2 and 3. A structure having a plurality of I-type internal members 4 that are integrally coupled to each other is known.
[0006]
[Problems to be solved by the invention]
The conventional composite wings do not have reinforcing parts like stringers on the upper and lower outer plates, so the plate thickness changes when the composite is cured even if molded using the inner jig 100% of the bonding surface cannot be ensured, and in the portions indicated by reference signs X and Y in FIG. is difficult, if not unlikely match, a gap between the outer panel 3 and the inner member 4 can not provide adequate adhesion pressure, poor adhesion between the outer panel 3 and the inner member 4 A portion is generated, and it is difficult to ensure adhesion quality at the joint between the outer plate and the internal member, to maintain the shape of the outer plate, and to control the appearance quality of the outer surface of the outer plate.
[0007]
When trying to form a composite wing by an integral molding method that tries to achieve the final shape by curing all components at the same time at once, the forming jig becomes complicated and expensive, and the upper and lower outer plates without stringers In the molding by combining the inner member and the inner member, the upper and lower outer plates are likely to be deformed, it is not possible to give sufficient bonding pressure to the corners of the inner member, and undulation and resin defects are likely to occur. It was necessary to provide it.
[0008]
In addition, some composite wings in the main wing class of passenger aircraft have a single-piece outer plate and internal member bonded together, but a reinforcing member such as a small bone must be placed to ensure strength. The jig becomes complicated, and the outer plate on the other side must be connected to the integrated structure of the outer plate and the internal member by fastener connection, which takes time and contains liquid such as fuel. Therefore, when liquid tightness inside the box is required, further work for preventing liquid leakage is required, which increases the cost.
[0009]
The present invention has been made in view of the above points, and an object of the present invention is to provide a composite blade having improved appearance quality and appearance accuracy, and a molding method therefor.
