Definitions
- Reservoir comprising a pultruded cylindrical element
- the present invention relates to a reservoir intended to contain a pressurized fluid.
- the invention also relates to its method of manufacture, as well as to its use for the storage, transport and/or distribution of fluid, and in particular of hydrogen.
- hydrogen is one of the fluids particularly studied.
- fuel cell vehicles are the subject of much research.
- one of the difficulties for the mass production of such vehicles is the design of the tanks. Indeed, the hydrogen tanks carried by these vehicles are subjected to pressures of use which can go up to 700 bars and must meet important safety requirements in order to limit as much as possible the consequences of a shock, accidental impact or fire.
- the tank when the tank is damaged during an accident in which the vehicle is involved or when a projectile fired by a firearm passes through the tank, it is desirable for the tank to release its pressure gradually, without exploding or breaking up. tear significantly. The same applies in the event of an increase in the temperature of the gas contained in the tank due to a fire in the vehicle.
- a significant advantage would be that they be easily inserted into an automobile body, in particular into the battery pack, to replace all or part of the batteries.
- Another objective is to allow such tanks to be obtained industrially at a reasonable cost, for example acceptable for an automobile application.
- a reservoir made of composite material comprising a tubular element, two end pieces respectively inserted into the ends of the tubular element, and a circumferential layer, which envelops the tubular element and the end pieces.
- the circumferential layer is formed of wound fibers impregnated with resin.
- the tubular element comprises a plastic tube surrounded by a longitudinal layer consisting essentially of fibers arranged parallel in a resin matrix, the parallel fibers being oriented in the direction of the longitudinal axis of the plastic tube.
- so-called conformable or else polymorphic gas storage tanks are generally composed of an assembly of tubes that are closed and connected to each other. These polymorphic tanks are manufactured by assembling small diameter composite tubes, typically with an inside diameter of less than 150 mm.
- thermosetting resin in particular of the epoxy type.
- these composites are generally microcracked, making it essential to use a thick and heavy liner to seal the tank.
- the microcracking of thermosetting composites, epoxy in particular, affects their mechanical strength and forces the carbon fiber content and therefore the cost of the tank to be increased.
- thermosetting resin in particular epoxy
- the invention relates to a reservoir for containing a pressurized fluid, comprising:
- At least one cylindrical element made of a pultruded fibrous material impregnated with a thermoplastic matrix
- the - at least one additional fibrous reinforcement enveloping partially or totally, preferably totally, the cylindrical element or elements, and possibly the end pieces, the fibers contained in the additional fibrous reinforcement, being positioned in an axis different from the longitudinal axis of the cylindrical element, the total fiber content of the reservoir being between 40 and 70% by volume with respect to the volumes of the matrix and the fibers contained in the tank.
- the invention also relates to a method of manufacturing the reservoir as defined above, characterized in that it comprises the following successive steps: a) pultrusion of the cylindrical element, b) positioning of the end pieces at the ends of the cylindrical element obtained at the end of step a), c) depositing additional fibrous reinforcement.
- the invention relates to the use of the tank as defined above for the storage, transport and/or distribution of fluid, such as gases, in compressed form, in liquid form or even cryocompressed, and including hydrogen, natural gas, LPG, LNG, compressed air, nitrogen, oxygen.
- fluid such as gases, in compressed form, in liquid form or even cryocompressed, and including hydrogen, natural gas, LPG, LNG, compressed air, nitrogen, oxygen.
- FIG. 1 is a diagram illustrating the process for preparing a cylindrical element made of a pultruded fibrous material impregnated with a thermoplastic matrix with an additional fibrous reinforcement for the tank according to the invention.
- FIG. 2 is a diagram illustrating another process for preparing a cylindrical element made of a pultruded fibrous material impregnated with a thermoplastic matrix with an additional fibrous reinforcement for the reservoir according to the invention.
- the reservoir according to the invention comprises:
- At least one cylindrical element made of a pultruded fibrous material impregnated with a thermoplastic matrix
- the additional fibrous reinforcement enveloping partially or totally, preferably totally, the cylindrical element or elements, and possibly the end pieces, the fibers contained in the additional fibrous reinforcement being positioned along an axis different from the longitudinal axis of the element cylindrical, the total fiber content of the reservoir being between 40 and 70% by volume relative to the volumes of the matrix and the fibers contained in the reservoir.
- the cylindrical element is manufactured using a pultrusion process. It is thus made up of fibers impregnated with a thermoplastic matrix. Pultrusion is a generally continuous process, which imposes traction of the fibers through a die in the axis of the cylindrical element, the fibers not necessarily being oriented in the axis of traction. Pultrusion covers the impregnation of dry fibers, for example dry fiber braids, dry fiber fabrics or uni-directional rovings. It also covers the implementation in the form of composite fiber profiles, pre-impregnated fibers, braids pre-impregnated with resin. According to the latter case, the fibers can be pre-impregnated before the pultrusion step.
- the tubes of the prior art consist of a tube called a “liner” then covered with fibers.
- the tank according to the invention comprises a cylindrical element, which already comprises fibers.
- This aspect of the tank according to the invention is very interesting. Indeed, the manufacture of cylindrical elements by pultrusion is productive, even for thick elements, because the entire volume of the cylindrical element is done continuously and in a single step.
- the incorporation of the fibers in the cylindrical element makes it possible to dispense with the removal in the axis of the tube of an impregnated fibrous reinforcement. Indeed, this removal step is relatively slow, and not always easy to master.
- the reservoir according to the invention may contain a liner. But, this liner is not essential. Fibers
- fibers forming said fibrous material are in particular fibers of mineral, organic or vegetable origin in the form of rovings.
- the number of fibers per strand is for carbon fibers greater than or equal to 12K, greater than 24K, in particular greater than or equal to 50K, in particular comprised from 24 to 36K.
- the grammage for the fiberglass is for each wick greater than or equal to 1200 Tex, in particular less than or equal to 4800 Tex, in particular comprised from 1200 to 2400 Tex.
- fibers of mineral origin mention may be made of carbon fibers, glass fibers, basalt or basalt-based fibers, silica fibers, or silicon carbide fibers for example.
- fibers of organic origin mention may be made of fibers based on a thermoplastic or thermosetting polymer, such as semi-aromatic polyamide fibers, aramid fibers or polyolefin fibers for example.
- they are based on an amorphous thermoplastic polymer and have a glass transition temperature Tg higher than the Tg of the polymer or mixture of thermoplastic polymer constituting the impregnation matrix when the latter is amorphous, or higher than the Tm of the polymer or mixture of thermoplastic polymer constituting the impregnation matrix when the latter is semi-crystalline.
- they are based on semi-crystalline thermoplastic polymer and have a melting point Tf higher than the Tg of the polymer or mixture of thermoplastic polymer constituting the impregnation matrix when the latter is amorphous, or higher than the Tm of the polymer or mixture of thermoplastic polymer of constitution of the impregnation matrix, when the latter is semi-crystalline.
- thermoplastic there is no risk of melting for the organic fibers of constitution of the fibrous material during the impregnation by the thermoplastic matrix of the final composite.
- fibers of plant origin mention may be made of natural fibers based on flax, hemp, lignin, bamboo, silk, in particular spider silk, sisal, and other cellulosic fibers, in particular viscose. These fibers of plant origin can be used pure, treated or even coated with a coating layer, in order to facilitate adhesion and impregnation of the polymer matrix. thermoplastic.
- organic fibers can be mixed with mineral fibers to be impregnated with thermoplastic polymer and form the impregnated fibrous material.
- the rovings of organic fibers can have several basis weights. They may also have several geometries.
- the fibers are in the form of continuous fibers, which make up 2D fabrics, nonwovens (NCF), braids or rovings of unidirectional fibers (UD) or nonwovens.
- the fibers making up the fibrous material may also be in the form of a mixture of these reinforcing fibers of different geometries.
- the fibers included in the pultruded fibrous material of the cylindrical element are a braid of dry fibers.
- the fibrous material is chosen from glass fibers, carbon fibers, basalt fibers and basalt-based fibers.
- the fibrous material is chosen from glass fibers.
