Description

PROCESS FOR MAKING SWAGED LIGHTING HOLES IN PLANAR AREAS OF PREIMPREGNATED COMPOSITE PARTS
FIELD OF THE INVENTION
This invention relates to a process for making swaged lighting holes in planar areas of preimpregnated composite parts, and particularly in parts made by means of automatic laying machines.
BACKGROUND OF THE INVENTION
The use of swaged lighting holes in structural parts is common in order to achieve an increase of stiffness without increasing the weight and with a minimum cost. The processes for making swaged lighting holes on sheet metal are common in industry and achieve the desired deformation of the sheet by means of its plastic deformation.
In the case of composite parts formed with stiff continuous fibers, however the mechanism allowing the adaptation to the desired shape of the swaged lighting hole is based on the relative slippage of fibers.
In parts made with composites, the traditional process for making swaged lighting holes consists of manually laminating each layer, adapting it to the geometry of the swaged lighting hole. This process is expensive, since it is completely manual and requires the use of materials that can adapt to the complex geometry of the swaged lighting hole without forming wrinkles. The most adaptable type of material is fabric, which, compared with the tape, is more expensive and has worse structural properties.
SUMMARY OF THE INVENTION
This invention proposes a new process for achieving swaged lighting holes in planar or quasi-planar areas of laminated parts of preimpregnated composite that is particularly applicable to parts made using preimpregnated tape the laminate of which is carried out with an automatic laying machine.
Parts of this type are used quite particularly in the aeronautical industry.
The process comprises the following steps:
- Arranging the part between a female tooling with the final shape of the bottom side of the swaged part and a caul plate with the final shape of the top side of the swaged part and applying pressure on the caul plate throughout the process to prevent forming wrinkles on the area of the part that must be maintained sufficiently planar. The caul plate will not act on the area of the part with the swaged lighting hole. - Applying a male tooling on the area of the part that must be swaged at a forward speed allowing flow of the resin during the slippage of the fibers of the composite such that said area can be deformed, adapting to the shape of the female tooling.
The process may additionally include the application of heat to the part while carrying out the process to achieve a temperature in the resin facilitating the slippage of the fibers of the material and a final cooling step if its handling is required immediately after making the swaged lighting hole.
Other features and advantages of this invention will be understood from the following detailed description of an illustrative embodiment of its object in relation to the attached drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 shows the starting part in the process according to this invention.
Figure 2 shows the part of Figure 1 after making two swaged lighting holes following the process object of this invention.
Figure 3 shows a part in which the flanges are formed first and after that the swaged lighting holes are made following the process object of this invention.
Figure 4 shows a schematic view of the part and of devices used to carry out the swaged lighting hole process according to this invention upon beginning the process.
Figure 5 shows a schematic view of the part and of said devices upon concluding the process.
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the process according to the invention for carrying out the swaged lighting hole 1 consisting, as is shown in the cases represented in
Figures 2 and 3, of a recess of an area 3 of the part 5 surrounding the opening 7, with an S-shaped contour, is described below. As the person skilled in the art will understand, the swaged lighting hole may have another shape.
The swaged lighting holes 3 are made in a planar or quasi-planar area of the part 5, but the latter may have a non-planar shape like the part 5 shown in
Figure 3, which corresponds to a rib with a C-shaped section, in which the flanges 6 have been formed prior to making the swaging according to this invention.
The part 5 is covered with a thin plastic film (not represented) to prevent it from adhering to the tooling of the swaged lighting hole process and is placed, suitably centering it, on a female tooling 11 the top side of which reproduces the shape that the part must be given during the swaging process, particularly including the cavity 13 with the desired shape for the swaged lighting hole 1.
A male tooling 17 and a caul plate 19 are arranged on the part 5. This caul plate 19 must cover the entire area affected by the movement that the swaging process will cause on the fibers of the composite, except in the very swaged lighting hole areas. The part 5 is therefore enclosed between the female tooling 11 and the caul plate 19, except on area 3.
The male tooling 17 is responsible for forming the part 5 with the shape of the female tooling 11 , and particularly forming its area 3 with the shape of the cavity 13. The male tooling 17 must initially be lifted above the part 5, which is achieved by supporting it on the female tooling 11 by means of springs 15.
The male tooling 17 may have the final shape of the swaged lighting hole 1 on its side that is applied on the part 5 or, as is shown in Figures 4 and 5, with the part 21 coming into contact with the part 5 made of a deformable material such that it may begin contact with the part in the area 23 where the swaged lighting hole begins and progressively become deformed until exerting pressure uniformly on the area 3 of the part 5 against the cavity 13 of the female tooling 11.
After the foregoing, the swaged lighting hole process is carried out in the following steps:
- Applying pressure P1 on the caul plate 19 such that the part 5 is enclosed and compressed between the caul plate 19 and the female tooling 11 , preventing the formation of wrinkles.
- In the case of using a material preimpregnated with a high viscosity resin, applying heat until achieving the suitable temperature to reduce the resin viscosity, facilitating the slippage of the fibers among one another. - Applying pressure P2 on the male tooling 17 so that it moves on the part 5 at a rate such that it allows the slippage of the fibers inside the part as the geometry of its area 3 evolves until achieving complete adaptation on the female tooling forming the swaged lighting hole 1.
- In the case of having heated the part 5 and a subsequent handling being necessary, cooling it to room temperature to return it to its initial consistency.
Any modifications comprised within the scope defined by the following claims can be introduced in the preferred embodiment described above.
