Definitions
- the present invention relates to a hinge made of composite material, in particular a hinge which may be fixed or integrated into two parts in composite material that must be connected to each other in a rotary manner.
- the present invention also relates to a process for manufacturing such a hinge.
- EP 1738895 describes a hinge comprising two groups of layers of carbon fibers impregnated with epoxy resin, which layers are arranged on and under a substrate of aramid fibers impregnated with a polyurethane resin. Said known hinge is complex and expensive to manufacture, as it requires layers of pre-impregnated fibers.
- WO 2012/035465 describes a hinge comprising two groups of layers of fibers arranged on and under two opposite edges of a substrate of material flexible and compatible for adhesion with resins for composite materials, so that a central portion of the substrate is not covered by these layers, wherein the substrate and the layers are embedded in a cured and flexible resin.
- the object of the present invention is therefore to provide a hinge free from said drawbacks. Said object is achieved with a hinge and a manufacturing process whose main features are specified in claims 1 and 18, respectively, while other features are specified in the remaining claims.
- the hinge according to the present invention allows to obtain a flexible portion having a flexural rigidity variable according to the distance from the rigid portion, so as to obtain a hinge relatively more resistant and more versatile than the known hinges.
- Such resistance can be considerably increased by applying particular layers of reinforcing fibers on the substrate and on the flexible sheets, in particular on holes made in these flexible sheets, so that the latter are "pinched" in the rigid portion of the hinge.
- the flexural rigidity of the flexible portion can be controlled easily by overlapping the flexible sheets with appropriate arrangements and dimensions.
- the aesthetic finish of the hinge is improved thanks to the clear and clean interface between the rigid portion and the flexible portion, which may be accentuated by a slit arranged between these portions.
- the substrate described in the Italian patent application MI2012A000307 and fabrics of carbon fiber described in the Italian patent applications MI2012A000244 and MI2012A000245 are particularly suitable for the application in the present hinge.
- the hinge can be manufactured with a particular process that is fast and easy to carry out, especially if layers of fibers pre-impregnated with resin are employed as reinforcement layers.
- Figure 1 shows a top view of a first embodiment of the hinge during a first step of the process
- Figure 2 shows the section II-II of Figure 1
- Figure 3 shows the hinge of Figure 2 during a second step of the process
- FIG. 4 shows the hinge of Figure 2 during a third step of the process
- Figure 5 shows the hinge of Figure 2 at the end of the process
- Figure 6 shows a top view of a second embodiment of the hinge during a step of the process
- Figure 7 shows the section VII-VII of Figure 6
- Figure 8 shows the hinge of Figure 7 at the end of the process.

- the first resin layer 4 is in turn comprised between substrate 1 and the first flexible sheet 5, which is, however, in direct contact with substrate 1 in said first portion Id of edge la not covered by the first resin layer 4.
- a second flexible sheet 7 comprising fibers is arranged at least partially on the first flexible sheet 5, so that at least one portion of the second resin layer 6 is comprised between the first flexible sheet 5 and the second flexible sheet 7.
- the second flexible sheet 7 is entirely arranged on the first flexible sheet 5, however in an alternative embodiment a portion of the second flexible sheet 7 may extend beyond the first flexible sheet 5 and be arranged on a first portion 1 e of substrate 1 adjacent to edge la, in which case the first resin layer 4 and/or the second resin layer 6 extend between the second flexible sheet 7 and the portion le of substrate 1 for joining the second flexible sheet 7 to substrate 1.
- Distance d2 between end lc of edge la of substrate 1 and the end of the edge of the second flexible sheet 7 arranged on substrate 1 is greater than 5 mm, in particular comprised between 5 and 50 mm, more in particular comprised between 15 and 25 mm.

- the first flexible sheet 5 and the second flexible sheet 7 are then comprised between substrate 1 and the fibers layers 10.
- four layers 10 of impregnated carbon fibers having a thickness comprised between 0,1 and 1 mm, in particular between 0,2 and 0,4 mm, and substantially the same shape are arranged at least partially one on the other on substrate 1, the first flexible sheet 5 and the second flexible sheet 7.
- Width w4 of layers 10 of impregnated carbon fibers is comprised between 20 and 50 mm.
- a sealing tape 11 is preferably applied onto an edge of the upper layer of fibers 10 and onto the upper flexible sheet, in particular the second flexible sheet 7, to create a barrier to the resin of layers 10.
- mold 2 provided with substrate 1, the flexible sheets 5, 7 and layers 10 of impregnated fibers is sealed in a vacuum bag and introduced into an autoclave, in which it is subjected to a pressure comprised between 3 and 6 bar and to a temperature comprised between 100 and 120 °C for a time comprised between 1 and 3 hours, so as to cure the first resin layer 4, the second resin layer 6 and the resin of layers 10 of impregnated fibers.
- Substrate 1 forms a single piece also with layers 10 of impregnated fibers both through the portion of these layers which are joined to substrate 1 and through the resin that has penetrated into holes 8, 9 of the flexible sheets 5, 7.
- a slot 14 is arranged between the rigid portion 12 and the flexible portion 13, namely between portion 5b of the first flexible sheet 5 not provided with the first resin layer 4 and portion Id adjacent to end lc of edge la of substrate 1.
- At least one edge 21a of a substrate 21 is arranged beside a rib 22a which protrudes from the functional surface of a mold 22.
- Rib 22a presents a substantially prismatic shape with a trapezoidal section, with base angles comprised between 80° and 90°.
- the height of rib 22a is preferably greater than the thickness of substrate 21.
- a portion 25a of a first flexible sheet 25 is applied onto substrate 21 by means of at least one first resin layer 24 which covers the surface of edge 21a of substrate 21 opposite to mold 22 up to its end adjacent to rib 22a.
- the first flexible sheet 25 protrudes from edge 21a of substrate 21 , overcomes rib 22a and continues on the functional surface of mold 22.
- a second flexible sheet 27 is applied onto the first flexible sheet 25 by means of a second resin layer 26 which covers the first flexible sheet 25 up to a portion adjacent to mold 22, i.e. arranged beyond rib 22a. Also the second flexible sheet 27 protrudes from edge 21a of substrate 21, overcomes rib 22a and continues on a second portion 25c of the first flexible sheet 25 arranged on the functional surface of mold 22.
