Definitions
- the present invention relates to the manufacture of a body formed from at least one organic thermoplastic material reinforced by continuous glass strands wound around the body. Although it is not limited to such an application, the invention will be more particularly described with reference to the manufacture of pipes, in particular those intended to convey fluids under pressure.
- the invention relates more particularly to pipes used in civil engineering, for the transport of liquids or gases, such pipes, generally rigid and able to withstand pressures which can be both internal and external, which can reach large dimensions and a weight Student.
- the pipes referred to in the present invention may have diameters of the order of one or a few centimeters to two or three meters, and a length of the order of several centimeters to several tens of meters, these pipes, weighing generally important, before, depending on the case, having resistance to deformation under pressures ranging from atmospheric pressure to several tens of bars, sealing over time, etc.
- Another interesting application is the manufacture of reservoirs (which can be formed in one piece, or from pipe (s) and attached end (s), etc.) intended to contain fluids in particular under pressure.
- the manufacture of a body based on at least one organic thermoplastic material reinforced by continuous glass wires wound around the axis of the body is already described in patent application WO 00/24566.
- a heated tape is wrapped, based on an organic thermoplastic material and continuous glass strands, around a rotating plastic tube while heating part of the surface of the tube coated with the ribbon and in applying pressure downstream of this heated part.
- the ribbon is by example obtained from continuous mixed yarns consisting of glass filaments and filaments of thermoplastic organic material intimately mixed, sold in particular under the trade name TWINTEX® by the company SAINT-GOBAIN VETROTEX FRANCE.
- the tube is generally extruded and made of an organic thermoplastic material which can for example be a polyolefin of the polyethylene PE or polypropylene PP type, or else polyvinyl chloride (PVC).
- the object of the invention is precisely to provide another less expensive method of manufacturing a composite body comprising an internal coating covered with composite material based on thermoplastic material and glass, this internal coating ensuring the same function as an extruded tube. , this process being suitable in particular for the manufacture of pipes or tanks as mentioned above, with specific constraints and requirements.
- the method of manufacturing a composite hollow body consisting of an internal coating and at least one external coating of composite material based on thermoplastic material and glass is characterized in that: - a powder is projected onto a support of a shape adapted to the shape of the hollow body so as to cover said support, this powder being intended to constitute the material of the internal coating; - A composite heated ribbon intended to form the external coating of the body is wound around the support covered with powder, the heat of the ribbon melting the powder and ensuring the joining of the ribbon with the powder, to constitute the composite body; - the composite body is extracted from the support after cooling.
- This simplified process thus makes it possible to obtain a product produced in a single piece which comprises both the internal coating and the reinforcing layer.
- the product is also lighter than a product of the prior art because the internal coating formed (the thickness of sprayed powder being generally less than 1 mm) is thinner than that made up to now of an extruded tube (the thickness of the extruded pipe generally being from 1 to 10 mm).
- the ribbon is deposited on the powder, possibly in combination with the presence of a heating source, at a temperature higher or lower than the melting temperature of the powder.
- the support can be heated internally and / or externally after the deposition of the powder over its entire surface and the deposition of the ribbon.
- pressure is applied against the tape after being deposited.
- the powder is projected by projection means which are movable relative to the support while the support is fixed, or vice versa.
- the tape As for the tape, it is deposited by a delivery and removal system which performs translational and rotational movements with respect to the support while said support is able to rotate during winding.
- the powder is a thermoplastic material, such as a polyolefin or a polyamide. It can advantageously be charged electrostatically.
- the ribbon comprises wires mixed with glass and with thermoplastic material, this also allowing a significant weight saving for the pipes more particularly targeted according to the invention.
- the invention also relates to a device for implementing the method described above. This device comprises a support (allowing the extraction of the composite body obtained after cooling, this support being called by removable support extension), means for projecting a powder onto the support, a system for delivering and depositing a ribbon. composite around the support covered with powder.
- the projection means and the support are able to be movable relative to each other, while the system for delivering and depositing the tape is capable of carrying out movements of translation and rotation vis-à-vis opposite the support, said support being adapted to perform rotational movements.
- the support can be made of an electrically conductive material to ensure the adhesion of the powder when in particular it is electrostatically charged.
- the support may include an outer plastic covering membrane.
- the support can be heated.
- the device can provide an external heat source which is arranged opposite the powder-coated support.
- the device may include additional heating means which are attached opposite the support after depositing the ribbon, and pressure means which are applied against the ribbon after being deposited.
- the invention provides a composite hollow body consisting of an internal coating and at least one external coating of composite material based on thermoplastic material and glass, the internal coating being obtained by melting a powder during the coating. of this powder by the external coating and by cooling.
- the internal coating is a thermoplastic material, such as a polyolefin or a polyamide for example, and the external coating is a ribbon, preferably of threads mixed with thermoplastic material and glass.
- the external coating is coated with a finishing and protective layer.
- FIG. 1 illustrates a schematic sectional view of a hollow body composite obtained according to the process of the invention
- FIG. 2 illustrates a general schematic representation of a device for manufacturing a composite hollow body according to the invention
- Figure 1 shows a schematic sectional view of a composite hollow body, here cylindrical in shape for use as a pipe, consisting of an internal coating 2 of a single material and at least one external coating 3 of composite material.
- the internal coating 2 is an advantageously compatible material for being in contact with the fluid circulating or stored in the hollow body.
- thermoplastic material such as a polyolefin of the polyethylene PE or polypropylene PP type, if necessary modified (for example with grafting of reactive polar groups), or else a polyamide.
- This material can be electrostatically charged, the advantage of which will be emphasized later in the description.
- This coating is at the start of the manufacturing process supplied in the form of powder with variable particle size and / or variable composition. The powder is then consolidated as soon as it is melted when the coating 3 is applied to it, and after cooling.
- the external coating 3 is formed using a composite tape which is made up of reinforcing threads, preferably glass threads, and of thermoplastic material.
- wires are advantageously intimately mixed, making it possible to form a very homogeneous consolidated band or ribbon, that is to say having a cohesion and an integrity which make it possible to handle this ribbon without damage.
- These are, for example, co-mixed yarns marketed under the trade name Twintex® by the company Saint-Gobain Vetrotex.
- Such a ribbon is for example made from spools of threads of the Twintex® type according to the method explained in patent application WO 00/24566 or in application EP 1 093 900.
- This protective layer preferably made of polyolefin, can for example be extruded, or be obtained by dusting (optionally preceded by heating the body) and heating (in particular coating, or baking). More simply, this layer can also be produced in the form of an aqueous or solvent-based paint adapted according to the constraints of use.
- the device 10 for implementing the method for manufacturing the hollow body 1 comprises a support 4 serving as a matrix for producing the internal coating 2 of the hollow body, means 5 for spraying a powder 20 constituting the internal coating 2, a delivery and removal system 6 of the ribbon 30 constituting the external covering 3.
- the support 4 is of a shape adapted to the shape that the hollow body must have. It is for example a mandrel for a cylindrical body, of diameter adapted to the desired section of the hollow body, in particular being expandable.
- the support is preferably metallic with a minimum roughness. When this support is made of several sections, it may be covered with a plastic membrane 41 such as silicone to prevent the junction between two sections from being reproduced in the form of a marking on the internal part of the internal coating 2 of the body after manufacture.
- the projection means 5 are for example in the form of a gun connected to a flexible powder supply pipe 50 20.
- the support 4 is movable in rotation around a shaft 40 and the projection means are suitable for move in translation, so as to deposit the powder 20 on the entire surface of the support to be covered to form the final shape of the hollow body.
- the support 4 may or may not be heating depending on the type of powder deposited.
- the powder 20 is a thermoplastic material as described above for the internal coating 2 obtained by consolidation of the powder 20 after heating and cooling. As examples of powder, the products can be cited
- the powder material may or may not be compatible with the thermoplastic material of the ribbon, we will then speak of an adhesion, between the powder and the ribbon, chemical or respectively mechanical.
- the tape delivery and removal system 6 is a head movable in translation and in rotation relative to the surface of the powder-coated support, the angle of inclination given to the head being adapted to the desired angle of circumferential or helical winding of the ribbon.
- the delivery and deposit head 6 comprises rotating and heating rollers at a heating and regulation temperature which makes it possible to maintain the ribbon at its outlet at a temperature 20 to 50 ° C. higher than the melting temperature of the thermoplastic material constituting the ribbon.
- a head is for example described in patent application WO 00/24566.
- the winding of the tape around the powder-coated support is obtained by the adequate inclination of the head and by the displacement in a plurality of back and forth thereof parallel to the longitudinal axis of the tube, as well as by its pivoting.
- the adhesion of the powder to the ribbon and its transformation into a consolidated coating are ensured by the melting of the powder and its cooling.
- the ribbon deposited on the powder has either a melting temperature of its thermoplastic material higher than that of the powder, or if it is lower, it is then necessary to bring a heating source to melt the powder.
- the temperature of the ribbon in the delivered state may be higher than the melting temperature of the powder, it may be that the difference between the two temperatures is too insignificant to ensure proper melting.
- a heating source 42 which is arranged opposite the support, at a distance of a few centimeters. It heats the support as soon as the ribbon is applied to the powder.
- the device 10 preferably comprises additional heating means 7 and pressure means 8.
- the additional heating means 7 may be constituted by the heat source 42. They are implemented immediately after the deposition of the tape or well when the winding is finished.
- the pressure means 8 consist of a pressure roller which is applied after one or more turns of the tape winding after the circumference of the powder-coated support, or once the winding totally finished. These means confirm the consolidation of the ribbon and of the molten powder and ensure a reduction in the void ratio between the various superimposed layers of ribbon.
- the heating source 42 and / or the additional heating means 7 such as the pressure roller 8 are able to move parallel to the support 4, for example using a mobile carriage carrying them. All the movements operated by the various mobile elements of the device (support, projection means, tape delivery and removal system, additional heating source, pressure means) are provided by one or more motors, and pneumatic means controlled by numerically controlled means. The manufacturing process will now be described.
- the mandrel 4 is rotated while the gun 5 in operation projects powder 20 and is moved in translation along the mandrel.
- the dispensing and delivery head 6 begins laying the tape 30.
- the head moves in translation along the mandrel while the latter is still rotating.
- the powder 20 melts to form the internal coating 2 and solidifies with the ribbon.
- the support can optionally be heated internally and / or its external surface in contact with the powder is heated just downstream of the tape deposit using the additional heat source 42 which is moved in translation along the mandrel while the latter rotates.
- the complementary heating means 7 and the pressure means 8 are implemented immediately after the laying of the tape, or else once the winding is finished, so as to locally heat the external peripheral surface of the body 1 and apply to this surface external pressure to fully secure the tape 30 with the internal coating 2. Once the body is cooled, it is extracted from the support.
- the above process is carried out on a single manufacturing station. It is of course possible to provide, for a variant of industrialization, at least two stations on which the powdering of the support and the winding of the tape are respectively carried out.
