Definitions
- the present invention relates to the stacking structure of a piece of composite material with a large change in thickness that is manufactured by autoclaving said stack and, more particularly, to the stacking structure of a piece of composite material of a structure aeronautics.
- layers of a composite material such as the prepreg which is a mixture of fibrous reinforcement and polymer matrix capable of storage are placed in a mold / useful.
- thermosetting matrices the resin is generally partially cured or taken by another process at a controlled viscosity, called B-stage.
- Composite fabrics are not placed randomly but are arranged in each area in a number and with an orientation of their fibrous reinforcement, typically of carbon fiber, determined according to the nature and magnitude of the efforts to be supported The piece in each zone.
- ATL Automatic Tape Lay-up
- Automatic wrapping machines are very efficient for manufacturing flat or substantially flat laminates since the slopes allowed by said machines are small. This limitation has the consequence that in those aeronautical structures with zones of different thickness there are that extend much the ramps of change of thickness especially when the differences of thickness are very pronounced, with the consequent impact on weight.
- the present invention is oriented to the solution of that problem.
- An object of the present invention is to provide a stacking structure of a piece made of composite material with a large change in thickness between two zones that facilitates its optimization in weight and dimensions.
- Another object of the present invention is to provide a stacking structure of a piece made of composite material with a large change in thickness between two zones that can be executed with an ATL machine.
- these and other objects are achieved by providing a piece with a first zone of a thickness E1 and a second zone of a thickness E2 that is made as a unit piece with a transition zone between said zones, whose outer surfaces have Earrings of magnitudes P1, P2, with a structured stack with:
- a plurality of fabrics that extend in the first zone and in the transition zone, ending staggered in the transition zone, to compensate for the difference in thickness between the first and the second corresponding zones on one side to the slope P1 and by other side to the slope P2.
- the stack structure comprises:
- a stacking structure optimized for parts with thickness changes is achieved, such as that corresponding to the area for taking out components of the trailing edge and / or of attack in the lining of the torsion box of a horizontal tail stabilizer of a aircraft, by taking advantage of the ramp that must exist in the cradle of stacking of said liner so that there is aerodynamic continuity between the liner and the leading edge and / or leading edge component, to configure an optimized transition zone in weight and dimensions.
- the mentioned objects are achieved with manufacturing processes of the piece comprising the stacking of composite fabrics on a stacking tool with the shape of the outer surface of the piece in different stages, depending on the structure of the stacking and curing in an appropriate device.
- Figure 1 a is a view of the assembly of the torsion box and the trailing edge of a horizontal tail stabilizer of an aircraft, with a torsion box whose lining is a piece with a large change in thickness and
- Figure 1 b is a partial detail view of a catch area of the drawer liner to a component of the trailing edge.
- Figure 2 is a cross-sectional view of a solution known in the art for assembling pieces of composite material with large thickness changes.
- Figure 3 is a schematic cross-sectional view of the assembly of pieces of composite material in which one of the parts is a piece with large thickness changes according to the present invention.
- Figures 4a, 4b, 4c and 4d are schematic views of the wrapping process of a piece with large thickness changes according to the present invention.
- the present invention is applicable to parts made of composite material with large thickness changes.
- parts made of composite material with large thickness changes in the aeronautical industry, it is worth mentioning the torsion drawer linings of the horizontal glue stabilizers shown in Figures 1 a and 1 b in which there is a large change in thickness between the lining 5 of the drawer proper and the skirt 7 to catch a panel 9 of the trailing edge.
- the outer surface of the lining 5 and the surface of the panel 9 of the trailing edge must be aligned to ensure aerodynamic continuity.
- the conventional solution of the prior art to be able to manufacture parts with different thickness zones together using an ATL machine is that the ramps of the transition zones between the zones with different thicknesses are compatible with the requirements of said machines.
- the basic idea of the present invention to achieve the objective that said piece can be manufactured as a unitary piece with a smooth transition between the zones of different thickness and limiting the length of the transition zone to the maximum is to use the step existing on the face external areas of different thickness, that is to say on the outer surface of the piece, to properly structure the stacking of the transition zone.
- the part 10 comprises: a first zone 11 of a thickness E1, a second zone 15 of a thickness E2 and a transition zone 13 between both of which surfaces 17, 19, of longitudinal dimensions L1, L2, respectively, have slopes P1, P2.
- the fabrics 31 of section 21 are taped that follow the outer geometry of the piece 10 and of the stacking cradle 49.
- the fabrics can be stacked by an ATL machine since the slope P1 is compatible with its requirements .
- the fabrics 33 of section 23 are taped.
- fabrics 33 in the transition zone 13 are "killed” causing a first decrease in thickness in the piece 10 corresponding to the step formed in the cradle 49.
- the fabrics 35 of the central section 25 are taped.
- the fabrics 37 of section 27 are taped.
- fabrics 37 in the transition zone 13 are "killed” forming a step and causing a second decrease in thickness in the piece. 10.
- the perimeter of these fabrics does not coincide in plan with the perimeter of the "dead” fabrics in the second stage. The "death” of these fabrics is therefore inserted between the "death" of the fabrics of the second stage.
- the fabrics 39 of section 29 are taped.
- the fabrics can be stacked by an ATL machine.
- the stack there could be continuous fabrics 31, 35, 39 continuous interleaved between the fabrics 33, 37 that die in the transition zone 13 in which case the ATL machine will be stacking successively on the stack cradle 49 both the continuous fabrics 31 , 35, 39 along the three zones 11, 13, 15 as the fabrics 33, 37 that "die” in the transition zone 13.
- the execution of the stacking one would proceed first to go killing fabrics against ramp 17 and once the stack has exceeded the thickness of the second part 15 continue killing fabrics on the other side (that of ramp 19) until the thickness of the first piece 11 is achieved.
- the slopes P1, P2 of the surfaces 17, 19 of the transition zone 13 must be equal to or less than the maximum allowable slope for a curb with an ATL machine that can currently be set at 1/5.
- the part 10 corresponds to the area where the torsion drawer lining is taken from a horizontal tail stabilizer to a component of the leading edge or the trailing edge illustrated in Figure 2, if the panel 9 has , for example, a thickness of 3.5 mm, that determines that, considering as maximum permissible slope for an ATL machine a slope of 1/5 the length L1 of the surface 17 of the transition zone 13 is 17.5 mm . From there, the length L2 and slope P2 of the surface 19 are determined by the difference in thicknesses of the coating 5 and the catch zone 7.
- the transition zone 13 normally has the shape represented in Figures 4a-4b with its two Ramp surfaces 17, 19 within a transition zone of length L because the difference in thickness of the lining 5 and the catch zone 7 allows the slope P2 to be equal to or less than P1. This is desirable because the length of the transition zone is optimized since the ramps are not suitable for joining other parts such as stringers in the case at hand. However, if the difference in thicknesses required by ramp 19 could have a greater longitudinal extension than ramp 17.
- the present invention is considered to be applicable for parts in which the difference between the thickness E1 of the first zone 11 and the thickness E2 of the second zone 15 is in the range 1.5-15 mm.
