Definitions
- the invention relates to a tank for storing a fluid under pressure, in particular hydrogen, comprising an elongated textile element, and its manufacturing method.
- the invention relates to a tank comprising an elongated textile element specific for the storage of gas, in particular compressed gas at high pressure, and its manufacturing method.
- batteries in electric or hybrid vehicles usually represent between 10 and 30% of the vehicle's weight. This excess weight causes a certain number of disadvantages, including in particular excess consumption of fuel or energy.
- the electric vehicle still suffers today from several problems, namely the autonomy of the battery, the use in these batteries of rare earths, the resources of which are not inexhaustible as well as a problem of production of electricity in different countries to be able to recharge the batteries.
- Hydrogen therefore represents an alternative to the electric battery, since hydrogen can be transformed into electricity using a fuel cell and thus power electric vehicles.
- Hydrogen tanks are generally made up of a metallic or polymeric envelope (also called a liner), which must prevent the diffusion of hydrogen outside the envelope.
- This first envelope must itself be protected by a second envelope (generally made of composite materials) intended to support the internal pressure of the tank (for example, 700 bars) and resistant to possible shocks or heat sources.
- the tank has a valve system, which must also be safe.
- conformable composite reservoirs that is to say reservoirs that can be inserted into volumes of complex and/or narrow shape, according to a at least three dimensions, such as, for example, the volume of a battery pack.
- One of the most promising types of conformable tank is composed of an assembly of small diameter composite tubes (typically with a diameter ⁇ 200mm) linked together by pipes.
- current processes allow the manufacture of tanks in one piece, typically 60 liters, therefore having a large footprint and at least impossible to insert into a battery pack, but are not suitable for the manufacture of small diameter tubular tanks.
- tanks with good mechanical strength at high temperatures, which are recyclable and conformable, have good gas tightness, and are easy to manufacture are currently sought after. These tanks would thus make it possible to store hydrogen but also any type of gas under pressure, and in particular under high pressure.
- a first step i) of manufacturing an elongated and unconsolidated textile preform comprising several layers of at least one thermoplastic composite ribbon, preferably several layers of ribbons, each layer comprising a ribbon wound at a given angle, without steaming , said preform being capable of being obtained from a specific device, shown in Figure 1;
- the manufacture of the preform according to step i) of the process of the invention can be produced continuously, and therefore provides rapid and inexpensive access to large textile preforms, particularly small diameters with great lengths.
- step i) of the method according to the invention makes it possible to superimpose a very large number of layers: the preform can contain as many layers of ribbon as desired modules used.
- the device implemented in step i) uses guides to deploy the ribbons in the same direction. It thus makes it possible to produce elongated textile preforms of different shapes, cylindrical or not.
- preform obtained according to step i) can also include section restrictions, at which certain ribbons can be cut and welded, and inserts positioned, in particular before consolidation.
- the preform can be easily bent at room temperature in order to give it a particular non-rectilinear shape which can then be frozen during the consolidation step ii). This will, however, require a particular choice of fiber orientations in the different layers of the preform.
- the method allows easy access to conformable tanks, which can in particular be inserted in a volume similar to an automobile battery pack.
- step ii) makes it possible to co-consolidate, within a single step, thermoplastic or metallic inserts, with the ribbons of the textile preform, making it possible in particular to close the tube to make it a reservoir, this which constitutes an additional economic advantage of the method of manufacturing tanks according to the invention.
- this co-consolidation makes it possible to improve the mechanical resistance and/or cohesion between the insert and the elongated co-consolidated textile element.
- the invention thus relates, according to a first aspect, to a method of manufacturing a tank, in particular for the storage of a fluid under pressure, comprising an elongated textile and consolidated element, said method comprising the steps of:

- the winding angle of the ribbon (10) relative to the direction X is between +90° and - 90°.
- the invention relates to a tank, in particular for the storage of a fluid under pressure, in particular hydrogen, comprising at least one elongated textile and consolidated element, capable of being obtained according to the process of invention.
- the tank according to the invention comprises one or more of the following additional characteristics:
- each consolidated elongated element is provided with an insert at its ends.
- the tank comprises several consolidated elongated elements, in series, connected to each other via connectors.
- the inventors were able to show that the tanks comprising an elongated and consolidated textile element obtained according to the process of the invention had very good mechanical strength compared to the composite tanks of the state of the art.
- the process of the invention allows the ribbons to be wound without steaming, which makes it possible to avoid local overstressing at the points where the fibers cross between them, and therefore to improve the mechanical resistance of the elongated textile element obtained after consolidation.
- the consolidation step ii) can be carried out under pressure, in particular under a pressure of between 5 and 10 bars, which allows both to further improve the mechanical resistance and to reduce the porosity of the composite material.
- thermoplastic composite ribbons do not allow high pressure to be applied, particularly for a prolonged period of time, so that the quality of consolidation is often quite low.
- the invention relates to a method of manufacturing a tank, in particular for the storage of a fluid under pressure, comprising an elongated and consolidated textile element, said method comprising the steps of:
- a frame (2) comprising a main longitudinal guide (3) in a direction X, said guide (3) being fixed on the frame (2) and
- each module (4) comprising:
- - feed means (6) arranged on the crown (5) capable of feeding at least one ribbon (10) towards the guide (3) at a winding angle of between -90° and 90° with the direction X and at an advance speed V1, each ribbon (10) being capable of winding at least around the guide (3) or on the upper layer of ribbon (10), and
- Step i) comprises the manufacture of an elongated textile and unconsolidated preform, using so-called textile ribbons, more particularly thermoplastic composite ribbons.

- the textile preform obtained at the end of step i) generally comprises several layers, in particular as many layers as modules (4) implemented. Each layer is formed by winding a ribbon, which may be of the same or different nature to that of the ribbon of at least one adjacent layer.
- non-composite thermoplastic ribbons can in particular be interposed between two layers of thermoplastic composite ribbon and/or constitute the internal layer of the preform and therefore of the elongated textile element after consolidation.

- the glass transition temperature(s) of the mixture depending on whether the compatibility is total or partial, must be between the glass transition temperatures of said polyamides before mixing and different from them, by at least 5° C, preferably at least 10°C.
- totally compatible means that when for example, two polyamides denoted PAa and PAb having respectively a Tga and a Tgb, are present respectively in two sealing layers or two adjacent reinforcing layers, and that Tga is less than Tgb , then the mixture of the two polyamides has only one Tgab, the value of which is between Tga and one Tgb.

- the ribbons 10 of the different modules 4 are deposited then on the secondary guide, and again on the main guide 3 after the passage of the secondary guide. It is thus also possible to greatly increase the diameter or section or even overall shape of the elongated element 11 during its manufacture.
- Such an elongated element 11 obtained is illustrated in Figure 10.

- the burst pressure of the tank is 1605 bars.
- the resulting tubular tank has a capacity of 10 liters and contains 2.98 kg of composite.
- the resin making up the matrix of the thermoplastic composite tape is 11/BACT/10T, the fiber used is Hyosung 2550 G10 carbon fiber, the fiber content is 53% by volume.
- the tensile breaking stress at 0° (fiber direction) of the composite obtained with the composite tape is 2700 MPa.
- the width of the tape is 14” and its thickness is 137 pm, on average.
- the preform has a section restriction corresponding to half of the initial diameter, making it possible to position a metal insert inside the preform.
- thermoplastic tape It comprises 10 layers of thermoplastic tape with a width of 14” and a thickness of 200 pm in polyamide 11 and 37 layers of thermoplastic composite tape, having a width of 14” and a thickness of 137 pm on average.

- the length of the tubular tank is 1.33 m, the internal diameter of 110 mm in the central part of the composite reinforcement, 55 mm in the restriction and the transition between the central part and the restriction is conical at an angle of 45 °.
- the thickness of the composite reinforcement is 5 mm and that of the polyamide 11 sealing layer, resulting from the consolidation of the thermoplastic ribbons included in the preform, is 2 mm.
- the internal diameter of the tank in its central part is therefore 106 mm and 51 mm in the restriction.
- the 2 layers are perfectly welded together and the tank is in one piece.
- This type of reservoir is type 4.5 (ie the sealing layer is of a different chemical nature from that of the composite matrix but the two resins are partially miscible, which allows perfect welding between them).
- the burst pressure of the tank is 1620 bars.

- the composite reinforcement is composed of an epoxy matrix and carbon fiber from Toray, ref T700 S, the fiber content is 70% by weight or 59% by volume (density of the carbon fiber used is 1.8 and that of epoxy resin is 1.1). It is manufactured by wet filament winding: the dry fibers are unwound from a creel and are impregnated with resin by passing at a speed of 0.8 m/s, in a bath containing the liquid precursor of the epoxy resin , at room temperature. 4 wicks are simultaneously wound around the liner. Each carbon wick has 1200 filaments (12K carbon wick), and has a linear mass of 0.83g/m. Taking into account the fiber content of 70% by weight, each impregnated wick has a linear mass of 1.18 g/m. Thus, the entire winding at 0.8m/s, with 4 strands in parallel, lasts approximately 2.7 hours. This step is followed by polymerization of the resin in an oven at 60°C for 8 hours.
- the manufacturing time of the type IV tank is much longer than that of the conformable type V tank of example 3, according to the invention and consumes much more composite and will therefore be significantly heavier and more expensive. since the price of carbon fiber is a major factor in the cost of the tank.
- the effectiveness of the composite reinforcement in the type IV tank is at least 2 times lower than that of the composite making up the type V tank of example 3: in fact, to contain the same volume of gaseous hydrogen (61 I) while withstanding the same internal pressure of 1600 bar, approximately 2 times more composite is required in the Type IV epoxy carbon composite tank than in the conformable PPA carbon composite tank.
