- FIG. 4 illustrates a first example of flap 26 for a motor vehicle front end air intake closure device 20, as illustrated in FIG. 2.
- the flap body 28 is constituted by a section of composite material, for example formed by two blades 30 assembled together.
- a composite material makes it possible to further reinforce the rigidity of this flap cops 28.
- composite material is meant here a plastic material comprising a reinforcing filler.
- this reinforcing load is made up of reinforcing fibers, in particular reinforcing fibers 42, 44, which are continuous.
- the reinforcing fibers 42, 44 extend obliquely with respect to the longitudinal direction X of the flap 26 and with respect to the transverse direction Y of the flap 26.
- the reinforcing fibers 42, 44 extend at an angle of about 45 ° with the longitudinal direction X and the transverse direction Y.
- Continuous fibers are here understood to mean fibers whose length is greater than 50 mm.

- Other fastening means of the end pieces 34, 36 can of course be used, these two end pieces 34, 36 can in particular be clipped, glued or screwed into or on the flap body 28.
- the two end pieces 34, 36 each form a relief 38, 40, or a finger or pin, receiving in a complementary housing of a frame 22, to allow the rotation of the flap.
- These reliefs 38, 40 have here a shape cylindrical of circular section.
- the reliefs 38, 40 are made in the extension of the longitudinal axis X of the flap 26, so that the flap 26, once mounted on the frame 22, is adapted to pivot substantially about its longitudinal axis X.
- the relief 38 also has a crown at its end, which, by cooperation with a housing of appropriate shape, limits or even avoids the translation of the flap 26 in the longitudinal direction X. It should be noted here that the relief 40 of the other end piece 36 may also alternatively present this crown at its end.
- the end piece 36 also has, as illustrated, a second relief 41, here of substantially cylindrical shape, for cooperating with the actuator controlling the pivoting of the flap 26 relative to the frame.
- first continuous reinforcing fibers 46 extend substantially in the longitudinal direction X of the flap body 28, whereas second reinforcing fibers 48, continuous or not, extend substantially in the transverse direction of the flap body 28, perpendicular to the first reinforcing fibers 46.

- a shutter device for a motor vehicle can then be produced by providing a frame, an actuator, and two end pieces.
- the two end pieces are fixed to the shutter body, the latter possibly being obtained by fixing two blades obtained as indicated above.
- Fixing the end pieces to the shutter body can be made by force insertion into the shutter body, by gluing, screwing, clipping or any other suitable fastening means.
- the flap is mounted on the frame, the cylindrical reliefs of the two end pieces being received in housing complementary section of the frame.
- ⁇ actuator is fixed on the flap, in particular on the relief 41 control and on the frame, if necessary.
- the pull-winding installation 200 differs from the pultrusion installation 100 of FIG. 6 mainly because of the presence of a device 202 making it possible to orient the reinforcing fibers with an angle of inclination with respect to the longitudinal axis and / or with respect to the transverse axis of the finally obtained section 118.
- a device 202 makes it possible to obtain a flap body 28 or a blade 30 that is even more resistant than with a pultrusion method as described above.

- the fiber-reinforced portion of the flap body 28 may in particular be one or the other, or both, of the larger faces of the flap body 28 substantially planar. These large faces of the shutter body 28 are thus more flexible, a priori, than the other faces of the shutter body 28, which are of smaller and / or curved areas, and therefore naturally more rigid.
- the insert 56 is covered by material, in particular by material in which the contour 54 is made, with the exception of the insert 56.
- the insert 56 forms integrally a portion of the contour 54.
- the insert 56 may not be covered by the material in which the remainder of the contour 54 is formed.
- the insert 56 is partially covered by the material in which the remainder of the contour 54 is formed. The insert 56 can thus be covered on one of its faces or on two of its faces by the material in which the remainder of the contour 54 is formed.
- FIG. 11 illustrates a variant of the example of FIG. 10, comprising three inserts 56 each connecting the two opposite faces of larger areas, of the flap body 28.
- the three inserts 56 are substantially evenly distributed over the width of these opposite faces of the flap body 28, to ensure a substantially constant stiffness over the entire closed contour 54.
- the three examples of shutter body 28 schematically illustrated in FIGS. 9 to 11 can in particular be made by extrusion.
- the insert (s) 56 may then be inserted into the flap body 28.
- the insert (s) 56 are coextruded with the rest of the flap body 28.
- the fibers 58 of the insert 56 may be pre-formed. resin-impregnated 60, for example of the same resin as that used to make the rest of the flap body 28.
- the fibers 58 may be dried until the extrusion process of the flap body 28, the fibers which can be impregnated only then, for example by means of a resin 60, in particular a low-viscosity resin.
- the reinforcing fibers may not be continuous, i.e. less than 50 mm in length. However, continuous reinforcing fibers are preferred to improve the mechanical strength of the flap.
- the flap body in the examples of Figures 4 and 5 is closed-section, hollow section.
- the shutter body may also be formed of a single blade or shell and not then present such a closed-contour section, hollow. Such closed-section hollow section, however, is preferred to improve the mechanical strength of the shutter.
