Definitions
- the present invention relates to a composite sandwich panel.
- Composite sandwich panels are materials that are more and more frequently used in various applications because of their excellent mechanical properties with respect to their low mass.
- a composite sandwich panel generally comprises a central layer forming a sandwiched core, sandwiched between an inner skin and an outer skin made of composite material, that is to say each consisting of one or more pre-fibrous folds. impregnated with resin which is then polymerized during a cooking step.
- a composite sandwich panel may also comprise several central layers, of the same type or of different types, the central layers may themselves be separated by a layer of composite material.
- the central layers may, for example, be cellular, balsa, foam, or include one or more fusible inserts.
- the inner and / or outer skins may have particular finishes depending on the final application of the panel.
- An example of finishing may be holes through the inner skin in the case of an acoustic panel.
- Other examples include conductive skins, waterproof, etc.
- composite sandwich panels are used in particular for floors, partitions, wing panels, etc. Indeed, many panels, initially made of aluminum could be replaced by composite sandwich panels, including a honeycomb structural core type Nomex, Kevlar or metal, for example, much lighter and providing excellent mechanical properties, which allows a significant relief of the planes and consequently leads to a reduction of the fuel consumption.
- zones of curvature in such panels are generally more fragile and must be reinforced because these curved areas constitute stress concentration zones because of the bending of the part. To do this, we then use hardware or heavy reinforcements in monolithic fabrics.
- the present invention relates to a composite sandwich panel comprising at least one core between an inner skin and an outer skin, each skin being made of composite material from a plurality of fibrous folds, characterized in that a part of the folds of the inner skin and / or the outer skin each extend at least partially through the core, at an interrupted zone of the latter, so as to form together at least one through reinforcement extending from the inner skin to the outer skin of the composite sandwich panel.
- the through reinforcement is made from at least one fold extending continuously from the outer skin to the inner skin. More precisely, one and the same fold can start from the inner (respectively external) skin, extend through the sandwich panel to constitute the through reinforcement, and then continue to expand by constituting a fold of the outer (respectively internal) skin. . The same goes for the part of the panel located on the other side of the reinforcement. Thus, a panel may even include several through reinforcements formed of peripheral folds.
- the panel has a curved section.
- the through reinforcement is located in the curved section.
- the through reinforcement is made perpendicular to the curvature of the panel.
- the through reinforcement is made substantially in the middle of the curved section.
- the latter comprises a cellular core.
- the panel is an acoustic panel.
- the core comprises a foam.
- the present invention also relates to an element of an aircraft, characterized in that it comprises a composite sandwich panel according to the invention.
- a composite sandwich panel 1 according to the invention as represented in FIG. 1, comprises an alveolar core 2 comprised between an inner skin 3 and an outer skin 4 composites each made from fibrous folds 5, 6, 7, 8 impregnated with polymerized resin.
- the composite sandwich panel 1 has a curved section constituting a stress concentration zone and thus forms a zone of fragility of the part. Accordingly, there is provided a through reinforcement 9 forming a radius of the curved section and oriented substantially perpendicular to the curvature of the composite sandwich panel 1 in this area.
- the through reinforcement 9 extending from the outer skin 4 to the inner skin 3 and is made from a part of the fibrous folds belonging to said inner skins 3 and outer 4.
- the alveolar core 2 is interrupted in the curved section at the level of said reinforcement 9 so that the latter extends through the sandwich panel 1.
- the outer skin 4 and the inner skin 3 comprise folds 5, 6 arranged outwardly of the sandwich panel 1 and extending continuously along said panel from a straight section to a second straight section while following the curved section.
- the outer skin 4 and the inner skin 3 also comprise folds 7, 8 arranged towards the inside of the sandwich panel 1 and extending along a straight section and over a portion of the curved section where they form the reinforcement crossing 9.
- the folds 7 extend continuously from the inner skin 3 along the cross-section, pass through the sandwich panel 1 at the curved section and form part of the folds of the reinforcement 9 and before extending to the outer skin 4 again along the cross section.
- the reinforcement 9 is formed by the folds 7 and the folds 8 from the straight sections.
- the folds 7, 8 constituting the reinforcement 9 are also impregnated with conventionally polymerized resin during a final manufacturing step.
- folds 7, 8 can continue to extend to form another reinforcements 9 in another curved section, and thus form peripheral folds.
- plies used may be identical in nature or different depending on the desired properties.
- the reinforcements may also be formed of folds of the same or different nature depending on the desired properties. In the case where the folds participating reinforcement alone do not present sufficient strength or should be reinforced, it will be possible to sew all or part of these folds between them. It will also be possible to insert in the reinforcement, between the plies, folds of reinforcements, such as folds of carbon fibers, for example.
- the reinforcement can be made during a preliminary step before application of the folds of the outer and inner ends in a second step.
