Definitions

  • the disclosed embodiment concerns a reservoir having a reservoir body, a liner and a composite body wrapped around the liner and at least one base plate and, in particular, the connection between a metallic liner and a composite structure in the zone of the base plate of a reservoir and is applied in particular in a high-performance reservoir of composite materials, especially a reservoir for high pressure liquid
  • the disclosed embodiment concerns the field of composite wound high-performance reservoirs intended for storage of liquids under pressure, especially for space applications and even more particularly for the storage of cryogenic liquids under pressure.
  • high performance reservoir refers to reservoirs optimized in terms of weight, such as are used in the transportation industry in general, space transport in particular.
  • the high-performance composite reservoirs intended for storage of pressurized liquids are generally designed with separation of the functions of sealing and of mechanical strength under pressure.
  • These reservoirs display an essentially thin shell of metal or polymer called the “liner”, whose purpose is to assure the confinement of the liquid and, in particular, the sealing and/or the protection of the wall of composite material of the reservoir with respect to the liquid
  • These reservoirs also have a winding of fibers of composite material which are then deposited by filament winding on the liner. The purpose of this winding is to assure the mechanical strength of the reservoir under pressure.
  • One of the problems with such reservoirs is that of the behavior of the liner during the use of the reservoir and especially the successive fillings and emptyings which subject the liner alternately to compression and traction/tension.
  • the operations of emptying involve compression of the liner by the composite.
  • the liner may have a sufficient thickness to support this compression without singeing due to the technologically useful minimum and the use of the liner as a tool for winding.
  • the total deformation of the liner connected on one side to the composite and on the other to the base plate may become very significant.
  • the level of deformation in the liner is also accentuated by the differential thermal expansion between the metallic liner and the shell of composite. This elevated level of deformation may lead to problems of the loss of sealing during the successive cycles of operation under pressure and [varying] temperature.
  • the composite can then move freely, the seal and the stable positioning of the base plates being assured by the liner.
  • This layer of a material called ⁇ shearing fold >> is traditionally an adhesive or a elastomeric fold used for its flexibility.
  • the disclosed embodiment therefore has as its objective to define a link/connecting joint between the liner and composite and between liner, composite and base plate of a reservoir/container, in the case of high-pressure high-performance reservoirs optimized in terms of weight.
  • This link/connection has the characteristic of not being used for elastomeric gluing between the composite and the base plate of the reservoir.
  • the disclosed embodiment has as its particular objective the design of a cryogenic container of large dimensions using composite materials.
  • the disclosed embodiment has the goal of permitting the use of a metallic sealing liner of very low thickness and whose minimal thicknesses is defined by the requirements of the service life of the reservoir when fatigued and tolerance for damages.
  • the disclosed embodiment proposes creation of a junction between a reservoir body displaying a liner and a composite body wound around the liner and a base plate of said reservoir through which the liner and composite body are glued to each other with the exception of an annular region surrounding the base plate.
  • the disclosed embodiment also involves a reservoir body, a liner and a composite body wound around the liner and at least one base plate through which the liner and composite body are glued to each other with the exception of an annular joint/junction region between the reservoir body and the base plate surrounding the base plate.
  • the disclosed embodiment assures the sealing in the zone of the base plate with the same strength and reliability as the existing solutions on reservoirs of more modest dimensions while assuring the storage of non-cryogenic liquid.
  • the reservoir is of general cylindrical shape with rounded ends, at least one of said ends containing the base plate and the annular region of the junction surrounding the base plate.
  • the liner is preferably connected to the base plate by welding or gluing.
  • the base plate advantageously displays a surrounding bead or collar, said wound composite extending onto the bead without being affixed to said bead.
  • the composite body preferably terminates at the level of the base plate by a roll supported on the bead.
  • the baseplate advantageously has a central cylindrical neck, on which a loop is mounted for retaining the roll.
  • annular joint is arranged between the loop and the roll.
  • the bead is preferably of a thickness decreasing toward its periphery
  • a layer of material of low coefficient of friction is arranged between the liner and the composite body and between the bead and the composite body.
  • the material with a low coefficient of friction is preferably a strip of PTFE (abbreviation for polytetrafluoroethylene).
  • the liner is advantageously made from pure aluminum in the annealed state.
  • the liner is preferably made of aluminum of the type 1050-O or 1100-O or 1050H111.
  • the disclosed embodiment also concerns a process for fabrication of the reservoir, in which one conducts a step of assembly of a liner with a base plate and then one winds a composite body on the liner and proceeds to a step of gluing the liner and the composite body to each other except in the annular region of the junction, between the body of the reservoir and the base plate, surrounding the base plate.
  • the process is advantageously such that after the step of assembling of the liner and the base plate, a material with a low coefficient of friction is applied to said annular region of the junction between the reservoir body and the base plate, surrounding the base plate, before the composite body is wound and the liner glued to the composite body.

  • the reservoir is of general cylindrical shape with rounded ends, at least one of said ends displaying the base plate 4 .
  • the baseplate 4 at the top of the reservoir serves, e.g., to hold the means of linking to the receiver to fill or empty it.
  • the composite body is created by winding composite fibers, such as carbon fibers impregnated by resin, and the composite body is wound on the liner and then glued ( 19 ) to the liner.
  • composite fibers such as carbon fibers impregnated by resin
  • the liner 2 and the composite body 3 are glued to each other on the cylindrical part 19 and on the part of the curved surface forming the top dome of the reservoir displaying the base plate but are not glued over an annular region 5 of the joint between the reservoir body and the base plate, said annular region surrounding the base plate.
  • the annular region is more specifically represented in FIG. 2 viewed in a cutaway of the top of the reservoir, this annular region 5 extending toward the base plate above a bead 7 of the base plate or bead of base plate denoting the peripheral end of the base plate, the bead called the wing of the base plate in the language of the field of the disclosed embodiment and the composite wound body extending over the bead without being affixed to the bead.
  • the annular region for which the composite body is detached from the liner and from the bead 7 of the base plate 4 is more specifically represented in FIGS. 3A to 3D depending on the conditions of use of the reservoir.
  • FIG. 3A represents the upper part of the reservoir displaying the annular region in cutaway view in a situation of rest, zero pressure and ambient temperature.
  • the liner When the pressure in the reservoir reaches its nominal value, as is the case in FIG. 3C , the liner is pushed toward the outside by the internal pressure Pi and, if the composite body is not glued either to the upper terminal part of the liner 2 or to the bead 7 , it may move back in direction C.
  • a layer 13 of material with a low coefficient of friction or anti-adhesive is arranged between the liner and the composite body and between the bead and the composite body.
  • This material with a strong coefficient of friction is, for example, PTFE tape, applied around the base plate and on the terminal part of the liner by helical application of both the liner and the bead linked together by welding or gluing at the level of their junction line 6 .
  • the composite body terminates at the level of the base plate in a roll 9 resting on the bead 7 and held by the button 11 .
  • the loop 11 retaining the roll is mounted on a central cylindrical neck 10 of the base plate.
  • An annular joint 12 is arranged between the loop and the roll in such a way that the loop presses moderately on the roll to hold it in a vertical direction parallel to the axis of symmetry of the base plate.
  • the neck of the base plate and the loop can be provided with complementary screw threads in order to mount the loop by screwing and thereby regulate the support of the loop on the roll.
  • the loop can also be glued at 14 to the neck of the base plate.
  • the bead or the wing of the base plate 7 is of a thickness decreasing toward its periphery.
  • the material properties of the liner will have the following specific features:
  • Pure aluminum in the annealed state (1050-O or 1100-O or 1050H111) is the preferred candidate for this liner, including in the cryogenic case.
  • the alloys of aluminum are denoted by using a numerical system of 4 digits, which identify the chemical composition of the alloy.
  • the series 1000 signifies at least 99% aluminum.
  • the second digit indicates a variant of the initial alloy. Frequently this involves a smaller range of one or more elements of the alloy.
  • the 3rd and 4th digits indicate, for the series 1000 , the minimal percentage of aluminum, e.g., 1050 indicating at least 99.50% aluminum.
  • the pieces of aluminum alloy obtained by deformation are classified in the metallurgical state. There are 5 normalized states classified by a letter.
  • the letter “O” means “annealed”.
  • the letter “H” which means “hammer hardened” is followed by 2 or 3 digits.
  • the first digit indicates the type of thermomechanical range.
  • the second digit gives the degree of hammer hardening and therefore the degree of the mechanical characteristic.
  • the possible third digit denotes a variant.
  • An example of application of the disclosed embodiment is a cryogenic capacity with a diameter of 1600 mm with a liner of 1050-O aluminum with a thickness of 1 mm.
  • the capacity is realized by having a usage pressure of 40 bar and a breaking/rupture pressure of 80 bar.
  • the height of the capacity according to the example is represented in FIG. 4 .
  • a blocking agent 15 closes the pin 4 and is fixed to said pin by a connection zone 16 .
  • the loop 11 attached to the neck of the base plate 10 is supported on the roll 9 of the wound body by a material of interposition 12 intended not to harm the composite.
  • the wound body covers the bead of the base plate and the upper part of the liner without being glued, a possible material 13 with a low coefficient of friction being inserted between the wound body and the bead/wing assembly and the upper part of the liner.
  • the radius of the base plate at the level of the neck of the base plate is of the order of 196 mm, the bead extending from there from the base plate over approximately 100-120 mm and the non-glued zone extending up to a distance at the axis of revolution Z of a capacity such that the radius of the capacity reaches R500 to 510 mm at this place.
  • the thickness of the liner is held constant in the non-glued zone in order to minimize the peak of deformation.
  • the variations of the possible thicknesses are localized in the zone where the liner is glued on the capacity.
  • the liner according to this example displays a thickness e 1 of 1.4 mm in the non-glued zone and e 2 of 1 mm on the remainder of the reservoir, which gives a content compatible with the sought application.
  • the liner is realized from a material with a high elastic limit, e.g., aluminum alloy 2219-T 87, which means that the principal alloying element is copper and that the primary phase present in the alloy is Al2Cu—Al2CuMg, T meaning that the alloy has undergone a heat treatment.

  • the functions of the loop 11 are, in particular, to prevent the introduction of forces to the liner and the glued joint during the non-pressurized phases, during the fabrication and/or the integration of the capacity, to keep the base plate united with the roll at the time of its cooling and to permit the displacement of the roll under the influence of internal pressure.
  • FIG. 6 represents the results of calculation in terms of cumulative plastic deformation of the liner along the axis Z starting at the origin and toward the zone of the base plate for the positive abscissas.
  • the curve 21 represents the deformation along the liner when it is cooled.
  • the point zero of the abscissa is a plane where the cylindrical part of the reservoir joins the bottom (where the bottom begins) and this point is called the “reference bottom.”

  • the point 24 of FIG. 6 is the zone where the gluing stops. It appears close to point 25 , because the graphic shows axial abscissas.
  • the materials for constructing the composite wound body are, for example, from the modulated carbon fiber, intermediate type T 800 by the Toray Co. (trademark registered) or IM 7 of the Hexel Co. (trademark registered) of the numerous variants that are possible.
  • FIG. 5 corresponds to a variant of the disclosed embodiment for which the liner is created in two parts 2 , 2 ′ glued at 17 , the second part forming an annular segment connecting the first part of the liner to the bead 7 of the base plate 4 .
  • the composite body is glued on the first part of the liner and the gluing of the composite body is extended over the second part 2 ′ of the liner in a zone of overlap of the two parts of the liner.
  • the composite body covers the second part 2 ′ of the liner and the bead 7 of the base plate without being glued.
  • This mode of realization permits creation of an excess thickness of the liner in the second part 2 ′ for increasing the mechanical strength of the reservoir.
  • a material with a low coefficient of friction is applied to said annular region 5 of the joint between the reservoir body and the base plate, surrounding the base plate, before the composite body is wound and the liner glued to the composite body.
