Definitions
- TITLE METHOD FOR MANUFACTURING A COMPONENT FOR THE FITTING OF AN AIRCRAFT CABIN
- the invention relates to the technical field of components for fitting out an aircraft cabin, such components being intended, for example, to equip seats.
- the technical background includes in particular documents DE-A1 -102010042349, EP-A1 -3 643 484, JP-A-S63 125315, US-A1 -2021/129453.
- Such a material generally comprises fibres embedded in a polymer matrix.
- a polymer matrix For example, it is known to use glass fibres, carbon fibres, etc.
- Other materials are also known for the production of such components, such as aluminium or plastic.
- carbon fibers are widely used in the production of woven composite parts in the aeronautics sector, particularly woven composite blades for turbojets.
- the layers of warp and weft threads are released as a preform of the composite part is created, in order to achieve the different desired thicknesses.
- a cutting operation is carried out. The cut carbon threads then become offcuts from the weaving process.
- carbon fiber waste represents a potentially significant volume across all production plants.
- carbon fibre scraps have mechanical performance that is still intact, because they have not been stressed. They can therefore be reused for the manufacture of new composite material parts.
- Carbon fibre offcuts are therefore not highly valued and outlets for the reuse of such fibres are still not very developed. They are mostly pyrolysed and then ground into powder constituting fillers for primers, paints or thermoplastic materials.
- the Applicant takes into consideration the impact factors in all phases of design and development to obtain less energy-intensive, more environmentally friendly aeronautical components and products whose integration and use in civil aviation have moderate environmental consequences with the aim of improving the energy efficiency of aircraft.
- the research and development work supported focuses in particular on lightening the devices, particularly through the materials used and lightened on-board equipment.
- the product comes in the form of a roll of a strip or a non-woven layer containing scraps of carbon fibers and a binder ensuring the cohesion of the fibers between them and the holding of the strip.
- the invention therefore aims to provide a method for manufacturing a component for fitting out an aircraft cabin, by recycling carbon fibre scraps.
- the invention is the result of technological research aimed at significantly improving the performance of aircraft and, in this sense, contributes to reducing the environmental impact of aircraft.
- the invention provides a method for manufacturing a component, in particular for fitting out an aircraft cabin, comprising at least: a) a production step, during which at least one non-woven layer comprising offcuts of fibers, in particular carbon fibers, impregnated with at least one binder, in particular thermoplastic, such as a thermoplastic matrix, which ensures cohesion of the non-woven layer, is produced; b) a consolidation step, during which the non-woven layer is consolidated, so as to obtain at least one fiber plate, in particular at least one laminated fiber plate; c) a cutting step, during which the plate is cut, and optionally, a superposition step, during which several cut fiber plates are superimposed and assembled together, so as to form a stack, in particular by welding them at several points by ultrasound; and d) a compression step, during which the fiber plate or stack is thermocompressed in a mold, so as to produce a component having a non-planar shape.
- a production step during which at least one non-woven layer comprising offcut
- the invention thus proposes to recover fiber scraps, such as carbon fibers, and thus to recycle them.
- the invention therefore makes it possible to produce development components from recycled material, which is particularly advantageous from an environmental and economic point of view.
- noble aeronautical materials such as carbon fibers
- an isotropic or quasi-isotropic non-woven structure particularly in the plane, with similar properties to those produced from woven structures, for example glass fibres, whilst significantly reducing the mass of the product.
- the term “furnishing component” should be understood as being a secondary structure component, in particular used to equip a seat, a piece of furniture, a storage chest and/or a trim panel for example. Such a component may have one or more functions chosen from an aesthetic finish, a fixing, etc.
- non-woven layer should be understood as being a layer composed of fibers which are not woven together and which have a random orientation in the non-woven layer.
- the fibers of the non-woven layer are bound together by at least one binder, a binding material and/or a matrix, in particular a thermoplastic matrix, which ensures a certain cohesion of the non-woven layer.
- the random orientation of the fibers is particularly advantageous because it allows the layer to have the same properties in all directions (isotropic or quasi-isotropic).
- Consolidation is to stiffen the non-woven layer and thus transform it into a relatively rigid plate. Consolidation can be a heat treatment, possibly associated with a compression treatment.
- the heat treatment may be carried out at a temperature greater than or equal to the glass transition or melting temperature of the binder, the binder material and/or the matrix.
- Thermocompression is a combination of heat treatment and compression treatment, which can, for example, be carried out in a press.
- the present invention may include other features, described in the following, which may be considered independently or in combination with each other:
- step c) the or each fiber plate is cut flat in step c) according to shapes corresponding to a development of the component
- the fiber plates are assembled by ultrasonic welding in step c), in particular at several points, so as to form a stack of variable thickness and/or in developed form of the component; - the fiber plate and/or the stack is heated, in particular by infrared or ceramic convection;
- the fiber plate and/or the stack is heated to a temperature greater than or equal to the glass transition or melting temperature of the binder, the binding material and/or the matrix, in particular the thermoplastic matrix;
- the stack is heated, stamped and consolidated in the mold which is regulated at a temperature lower than the solidification temperature of the binder, the binding material and/or the matrix;
- the mold is configured to form at least one variable thickness, a rib, a groove and/or a hole;
- the mold is regulated at a temperature, in particular at a temperature lower than a solidification temperature of the binder
- the binder is poly(phenylene sulfide) (PPS), polyetherimides (PEI), polyetheretherketone (PEEK), polycarbonate (PC), polyethersulfone (PESU) and/or polyphenylsulfone (PPSU);
- PPS poly(phenylene sulfide)
- PEI polyetherimides
- PEEK polyetheretherketone
- PC polycarbonate
- PESU polyethersulfone
- PPSU polyphenylsulfone
- the compression step d) includes and/or is followed by overmolding of the component
- the cut and superimposed fiber plates are assembled by welding, in particular ultrasonic welding, in particular by point welding, to each other at the superposition stage, so that the stack is in one piece, in particular making it easier to handle the stack before thermocompression;
- the component is intended to equip an aircraft seat or is a component of such a seat.
