Definitions
- Molding tool for producing a composite material part by means of a flexible preform consisting of a skin and profiled preforms secured to said skin.
- the invention relates to a molding tool for producing a piece of composite material by coating, by means of a matrix, a flexible preform composed of a skin with a fibrous structure and, secured to said skin, of profiled soft preforms with a fibrous structure each comprising a core, arranged in such a way that said webs delimit, above the skin, a plurality of three-dimensional meshes of polyhedral shapes.
- Composite materials composed primarily of fibrous structure preforms, and a matrix generally consisting of a plastic material (thermoplastic or thermosetting resin) ensuring the cohesion of the structure, are used more and more frequently in many industries, particularly in the aerospace industry.
- the manufacture of composite material parts requires, first of all, to produce profiled preforms of section and / or more or less complex shapes, by means of elementary preforms cut and then shaped and / or mechanically assembled to obtain the profile. longed for.
- Such profiles are then frequently secured to skins with a fibrous structure, so as to produce panels made of composite materials comprising reinforcing structural elements.
- the different sections and the skin are then compacted before being installed in a molding tool in which they are then assembled by coating using a matrix.
- patent document EP 1 000 725 describes a mold matrix whose stainless steel materials have different thermal expansion coefficients to define internal cavities to pre-compress the body to be molded.
- the present invention aims to overcome these drawbacks and its main purpose is to provide molding tools for coating, by a matrix, flexible preforms previously compacted.
- the invention relates to a molding tool for producing a composite material part by coating, by means of a matrix, a flexible preform composed of a skin with a fibrous structure and, secured to the said skin, profiled soft preforms with fibrous structure, said profiled, each having a core, arranged so that said souls delimit, above the skin, a plurality of three-dimensional meshes of polyhedral shapes.
- this molding tool comprises:
- a mold with a sole, said lower sole, adapted to support the skin of the preform, and a peripheral belt defining a volume adapted to accommodate said preform,
- a one-piece piece for filling the volume of the mesh formed by the assembly:
- a plurality of shims adapted to be interleaved and forming a lining wall of the webs of the profiles, delimiting a free central volume inside the three-dimensional mesh,
- a locking piece adapted to fit into the free central volume of the three-dimensional mesh and to ensure relative blocking of said blocking piece and shims, - and a counter-mold with a sole, said upper sole, closing the mold,
- the mold and the counter-mold being made of a material having at least substantially the same coefficient of expansion as the fibrous structure of the preform
- the shims and the locking pieces being made of a material designed to produce a one-piece piece having a coefficient of expansion adapted to obtain a predetermined compaction of the skin and the profiles, for a predetermined temperature corresponding to the polymerization temperature of the matrix.
- the tooling is designed to produce a composite material part by coating a flexible preform, that is to say a preform that has not been compacted prior to the molding operation.
- This compacting is in fact carried out according to the invention thanks to the design of monoblock controlled expansion pieces, which make it possible to compact the various pieces with a fibrous structure directly in the tooling, before coating the latter with a matrix .
- the various preforms (skin, profiles, etc.) can thus be assembled by seam lines before being coated, and such sewing lines lead to the production of composite panels capable of withstanding tearing efforts.
- the shims of each three-dimensional mesh comprise corner shims adapted to be arranged in each corner of said three-dimensional mesh, and wedge wedges adapted to secure the corner shims.
- the shims of each three-dimensional mesh advantageously delimit a central volume having the general shape of a truncated pyramid of decreasing section towards the upper sole of the mold, the locking piece consisting of a wedge-shaped piece of that of the said central volume.
- the wedges and the locking parts of the three-dimensional meshes are advantageously adapted, according to the invention, to delimit flat faces of support of said soles.
- the against-mold then advantageously comprises an upper sole adapted to press the soles on said flat support faces.
- the locking piece of each three-dimensional mesh has a height adapted to form an extension in the extension of the corresponding central volume, the counter-mold having, for each of said three-dimensional meshes, a recess of shape adapted to accommodate said extension of the locking piece.
- the mold integrates, for each of said peripheral profiles with soleplate. , a removable lateral stop block of said profile designed to be removed after solidification of the sole.
- one of the advantageous applications of the tool according to the invention consists in producing a part made of composite material comprising a curved wall.
- the mold has a curved lower sole and each wedge consists of two superimposed wedges:
- a wedge called a lower wedge, having a curved underside of conjugate shape of the upper sole of the mold
- upper wedge provided with a flat upper face for supporting a sole
- the lower wedges of each three-dimensional mesh define an upper face of generally concave shape, the upper wedges defining a bottom face of generally convex conjugate shape of said concave upper face.
- the invention allows the production of a composite material part comprising at least one peripheral profile with a sole, secant with respect to the plane of curvature.
- the removable lateral stop abutment of this profile is advantageously constituted by two superimposed shims, lower and upper.

- This mold further comprises, along each of the transverse sides of the rib 5, a transverse shim 7, 8 curved, lateral stop of each of the peripheral cross members T of the panel Pr.
- this mold 1 comprises two longitudinal shims positioned so as to extend each between one of the end sections of the two transverse shims 7, 8.
- each of these longitudinal wedges is in fact made up of two superimposed longitudinal wedges 9, 10 designed to form a wedge that can notably be slid laterally under the outer wing of one of the perimeter longitudinal members L1 of the preform Pr, and be removed after polymerization despite the undercut that forms this outer wing.
- these two lower and upper 10 wedges 9 have substantially complementary trapezoidal sections, so as to form, once superimposed, a wedge with substantially parallel upper and lower faces.
- their junction faces are inclined relative to the upper and lower faces so as to remove the upper shim 9 without exerting stress on the polymerized preform.
- the mold 1 comprises, by elsewhere, a longitudinal locking wedge 11 of shape adapted to be positioned between each longitudinal wedge 9-10 and the corresponding longitudinal side of the rib 5.
- the tooling according to the invention also comprises, for each three-dimensional mesh 11-115, a one-piece piece for filling the volume of this mesh, removable into a plurality of basic elements designed to be able to:
- FIGS. 4a to 4c represent, by way of example, the various constituent elements of the one-piece piece adapted to be housed in the mesh 11 of the preform Pr.
- These elements comprise, in the first place, a first series of eight wedges adapted to rest on the skin P by their lower face and to form the lower bearing Cinfl of a lining wall of the souls of the profiles L, T, delimiting a central volume free 28 having the shape of a truncated pyramid of decreasing section towards the mold 1.
