Definitions
- the present invention relates to a method of manufacturing a metallic material reinforced with an organic matrix composite.
- the invention also relates to a process for obtaining a structural part in a material resulting from such a manufacturing process.
- the structure of a vehicle also called a white body, is today mainly made of steel. Although the mechanical properties of steel have changed, its particularly high density (of the order of 7.8) remains a major obstacle to lightening the structure. Reducing the weight of the body in white therefore necessarily involves the introduction of lighter materials and in particular composites whose density can be up to substantially five times lower than that of steel.
- the composite patches represent additional parts to be fixed to the structure, which generates an increase in assembly time and therefore in the cost of the vehicle.
- the object of the invention is therefore to propose a method for manufacturing structural parts in a reinforced metallic material which at least partly obviates the aforementioned drawbacks.
- the invention provides a method of manufacturing a metallic material reinforced with an organic matrix composite.
- the process includes the steps of:
- the resin completely covers the upper surface of the metal sheet
- the resin partially covers the upper surface of the metal sheet.
- the resin partially covers the upper surface of the metal sheet in the lengthwise direction of said sheet.
- the metal sheet is obtained by cutting an unwound strip from a coil.
- the material can thus be produced in an industrial and continuous manner, that is to say being more particularly compatible with the production rates of the automotive industry.
- the fibrous reinforcements comprise carbon fibers and / or glass fibers.
- carbon fibers and glass fibers make it possible to obtain a composite having good mechanical properties while being significantly lighter than the corresponding metal.
- the fibrous reinforcements come from a roller for distributing glass fibers and / or carbon fibers.
- the fibers can thus be distributed in an industrial and continuous manner, that is to say being more particularly compatible with the production rates of the automotive industry.
- 1 / invention also relates to a process for obtaining a structural part in a reinforced metallic material resulting from such a manufacturing process.
- the method comprises the additional steps of;
- FIG. 1 schematically represents a process for manufacturing a reinforced metallic material according to a particular embodiment of the invention
- FIG. 2 is a perspective view of a material resulting from the process illustrated in FIG. 1,
- FIG. 3 schematically represents the process for obtaining a structural part in the material illustrated in FIG. 2,
- FIG. 4 is a perspective view of a structural part obtained from the material illustrated in FIG. 2.
- FIG. 5 is a perspective view of a structural part obtained in a variant of the material illustrated in FIG. 2.
- a coil 1 of a metal strip is rotatably mounted around a axis Y1 orthogonal to the plane of said figure.
- the unwinding of the reel takes place along a horizontal axis XI to unwind the strip along the same axis XI to form a metal sheet 1.1.
- the axis Y1 of rotation of the reel 1 is orthogonal to the axis XI of unwinding of the strip.
- a distribution roller 2 of fibrous reinforcements 2.1 is mounted so as to be able to rotate about an axis Y2 orthogonal to the plane of FIG. 1.
- the axis Y2 of rotation of the distribution roller 2 is parallel to the axis Y1 of rotation of the reel 1.
- the unwinding of the fibrous reinforcements 2.1 takes place, at the outlet of the distribution roller 2, along an axis X2 forming an angle a with the axis XI of unwinding of the reel 1.
- the angle a is here substantially equal to 50 degrees.
- the fibrous reinforcements comprise for example carbon fibers and / or glass fibers.
- the metal sheet 1.1 and the fibrous reinforcements 2.2 then meet to pass together between a first cylinder 3.1 and a second cylinder 3.2 intended to guide the unwinding of the coil 1 and the distribution of the fibrous reinforcements 2.1 along the axis XI.
- the first and second guide cylinders 3.1, 3.2 are arranged one above the other and are mounted free in rotation around axes parallel to the axis Y1 of rotation of the coil 1 and the axis Y2 of rotation of the distribution roller 2.
- the metal sheet 1.1 and the fibrous reinforcements 2.1 are respectively in contact with the first cylinder 3.1 and the second guide cylinder 3.2.
- the fibrous reinforcements 2.1 thus cover, at the outlet of the guide cylinders 3.1, 3.2, at least part of an upper surface of the metal sheet 1.1.
- the rotational speeds of the reel 1 and of the distribution roller 2 are coordinated so that the distribution of the fibrous reinforcements in output of the guide cylinders 3.1, 3.2 is synchronized with the unwinding of the metal sheet 1.1 according to XI.
- a distributor 4 of a liquid thermoplastic resin 5 is arranged at the outlet from the guide cylinders 3.1, 3.2.
- the resin 5 is deposited by gravity on the upper surface of the metal sheet 1.1 so as to impregnate the fibrous reinforcements 2.1 of said resin 5.
- the fibrous reinforcements 2.1 and the resin 5 then form a composite with an organic matrix.
- Resin 5 is, for example, Elium® resin from the company Arkema.
- the fibrous reinforcements 2.1 here form a grid and cover, with the resin 5, only partially the upper surface of the metal sheet 1.1.
- the composite thus forms a strip extending substantially in the center and in the direction of the length of said sheet 1.1.
- a total covering of the upper surface of the metal sheet 1.1 by the composite is also possible, just like a partial covering in the width direction.
- heating means 6 for heating the composite to a predetermined temperature to polymerize the resin 5 under the effect of a catalyst.
- the predetermined temperature for the polymerization of the resin 5 is preferably between 50 and 180 degrees Celsius (° C).
- the heating means 6 can, for example, be of the infrared, forced air type, or even by induction of the metal sheet 1.1.
- the horizontal behavior of the metal sheet 1.1 and of the composite is ensured by cylinders 7 for conveying arranged in particular below the heating means 6.
- the metal sheet / composite assembly then pass between compacting and impregnation cylinders 8.
- the cylinders 8 in particular exert pressure on the composite in the direction of the metal sheet 1.1 to bond said composite to said metal sheet and thus form a metallic material reinforced by an organic matrix composite.
- the material is then in the form of a strip of width substantially equal to that of the metal sheet 1.1.
- the upper surface of the metal sheet 1.1 has previously undergone a surface preparation operation P making it possible to improve the adhesion between the resin 5 in the polymerization phase and the upper surface of the metal sheet 1.1
- the preparation operation surface P can for example be carried out by laser, by mechanical abrasion or by chemical treatment.
- a cutting tool 9 makes it possible to cut a portion 10 of said material to predefined dimensions corresponding substantially to those of a structural part 11. As illustrated in FIG. 3, the cutting tool 9 allows for example to define a length L of the portion 10 of material and to create lateral 10.1 recesses in areas not covered by the composite.
- the width 1 of the portion 10 is here substantially equal to that of the metal sheet 1.1.
- the cut portion 10 is heated to a predefined temperature by means of a heating system 12 (FIG. 3).
- the heating of the cut portion 10 makes it possible to prepare its stamping without risking the appearance of zones of fatigue or even rupture of the material.
- the predefined heating temperature depends on the intrinsic qualities of the composite and is preferably between 150 ° C and 350 ° C.
- the heated portion 10 is thus inserted between a die 13.1 and a punch 13.2 making it possible to give said portion 10 the shape of the structural part 11.
- the structural part 11 here has the shape of a tunnel whose lateral ends 11.1 are not covered with composite.
- the lateral ends 11.1 can advantageously serve as areas for fixing by welding the structural part 11 to one or more metallic elements that said structural part 11 will overlap.
- FIG. 5 illustrates a structural part 11 ′ of shape similar to the structural part 11 previously described. The difference lies in particular in the fact that the structural part 11 ′ is made from a material in which the composite covers the entire metal sheet 1.1.
- the fibrous reinforcements comprise carbon and / or glass fibers, they can also comprise other types of fibers such as for example vegetable fibers, aramid or polypropylene fibers ...
