Definitions
- the present invention relates to textile reinforcements used as reinforcing products of composite articles, that is to say articles based on resin (polyester or other) armed with a reinforcement textile reinforcement.
- the invention more particularly relates to textile reinforcements for the production of composite articles by a pultrusion process.
- Pultrusion is a process for continuously forming plastics including reinforcing elements and having a constant cross section.
- the product is pulled out of a die in which the reinforcing elements are overmolded and impregnated with a resin.
- the resin is generally a thermosetting plastic.
- the die itself is heated. At the outlet of the die, after cooling, the product is cut to the desired lengths, thus forming profiled composite articles reinforced by the reinforcing elements.
- the reinforcing elements are generally made of fibers, and thus form a continuous textile reinforcement.
- the continuous textile reinforcement In its passage through the pultrusion die, the continuous textile reinforcement undergoes braking constraints, and it is necessary to put it under tension to ensure its maintenance in shape.
- the drive of the textile reinforcement through the die therefore requires applying on the continuous textile reinforcement longitudinal drive forces, essentially in traction.
- pultrusion requires the use of a continuous textile reinforcement, which therefore has a longitudinal dimension much larger than its transverse dimensions.
- a continuous textile reinforcement which is initially flat, tends to deform by forming corrugations in the transverse direction, in the same way that a tie is deformed. that we pull down. If such a deformation of the textile reinforcement occurs before entering the pultrusion die, this reduces the width of the reinforcement and may produce wrinkles. This deformation of the reinforcement, and the risk of defects that result, all the more tend to occur when the frame has a large width in terms of its thickness.
- Continuous textile reinforcements based on continuous glass fibers are known, which have the advantage of giving the products made by overmolding these reinforcements a high mechanical strength thanks to the advantageous properties of the glass fiber.
- These continuous reinforcements are generally in the form of a flat strip.
- a method for producing such a continuous reinforcement is described in US Pat. No. 3,969,171: the glass filaments leaving the glass extrusion die are put together to form glass threads that are randomly deposited in all directions. guidance on a band carrier. A binder is sprayed onto the glass strands and then treated in an oven. This method does not allow to control the direction of mechanical strength provided by the presence of continuous glass son, and it does not confer sufficient longitudinal mechanical strength for a pultrusion application.
- the document WO 95/34703 A1 describes a textile reinforcement for producing composite parts by pultrusion.
- This reinforcement comprises a layer based on glass fibers and polyester, in which the glass fibers are in the form of randomly oriented stretches of glass fiber coated with polyester.
- the reinforcement must be combined with continuous longitudinal filaments (roving) and external sails, the continuous longitudinal filaments having the function of conferring on the reinforcement a mechanical resistance to the elongation sufficient to withstand traction during pultrusion. This significantly complicates the pultrusion process, the need to assemble and hold in position in the die several elements.
- reinforcement textile reinforcement that have been proposed to date do not have a satisfactory structure that can withstand a pultrusion process and make relatively large profile pieces.
- a problem proposed by the present invention is therefore to design a new textile reinforcement structure which is particularly suitable for pultrusion processes, in that it has both good longitudinal tensile strength and good resistance to wear. transverse deformations likely to occur during a pultrusion process, so that the textile reinforcement can be used during the pultrusion process without adding other reinforcing elements such as continuous longitudinal son in the die.
- Another problem proposed by the present invention is to design a method and a device for producing a novel fiberglass-based textile reinforcement structure which is particularly suitable for pultrusion processes.
- the invention provides a textile reinforcement that can be used for the production of composite parts by pultrusion, comprising a reinforcing layer having randomly oriented sections of glass fibers coated with a polyester binder. , in which :
- the reinforcing layer comprises at least one reinforcing layer formed of structured fibers in weaving, or in grid, or in longitudinal and transverse yarns,
- the reinforcing layer comprises at least one layer of thickness, adjacent to the reinforcing layer, and based on said randomly oriented sections of glass fibers and coated with a polyester binder,
- At least a first surface layer of fiber web forms a first external face of the textile reinforcement
- a second external face of the textile reinforcement is formed by said at least one reinforcing layer or by a second surface layer of fiber fleece,
- the polyester binder ensures the connection between the layers of the textile reinforcement.
- the textile reinforcement has good resistance to transverse deformations during a pultrusion method.
- the reinforcing layer makes it possible to give the textile reinforcement mechanical resistance properties in the longitudinal direction and in the transverse direction. This substantially distinguishes the armature according to the present invention from armatures commonly used in pultrusion techniques, which consist essentially of son oriented in all directions and randomly.
- Such a known reinforcement necessarily has insufficient longitudinal mechanical strength, which requires the addition of fibers of longitudinal glass at the time of pultrusion. But this addition of longitudinal glass fibers does not participate in the transverse strength of the reinforcement, which remains insufficient.
- the reinforcing layer structured so as to additionally give the textile reinforcement mechanical strength properties in the transverse direction, makes it possible to produce reinforcements of greater width, which are adapted to then be produced by pultrusion. profiles of great width, without risk of inadvertent deformation.
- the polyester binder which provides the connection between the layers of the textile reinforcement, simultaneously ensures a smooth character to the two outer faces of the textile reinforcement.
- the fiber-veiled surface layer forms a smooth outer face, which can impart a particularly smooth and finished surface finish to the composite part made by pultrusion from the reinforcement thus formed.
- the surface layer fiber veil formed from relatively thin fibers, has a smooth appearance and hides the fibers of the central layer of the frame.
- the outer layer of fiber veil forms an outer frame which facilitates the manufacture of the frame, in that it avoids the bonding of the frame during manufacture on a conveyor belt.
- the surface layer of fiber fleece may itself consist of colored fibers, which then give the products resulting from the pultrusion a colored appearance taking up the color of the surface layer of fiber fleece. It is thus possible to produce colored pieces, and the color changes from one production to another can be very easy by simply changing the surface layer into a fiber fleece, without having to carry out complicated and expensive cleaning of the die for change, for example, the color of the resin injected into the die.
- the sections of glass fibers in said at least one layer of thickness are fiber sections obtained from strands (roving) of glass yarns, currently available products.
- the sections of glass fibers in the layer of thickness may advantageously comprise glass strands having a linear weight of 40 at 50 tex, that is to say 40 to 50 grams per kilometer of wire.
- the strands of glass strands can have a linear weight of 600 to 2400 tex.
- the polyester binder which provides the bond between the layers of the textile reinforcement is an unsaturated bisphenol polyester, soluble or insoluble in styrene. This facilitates its fusion to coat the glass fibers during the manufacture of the textile reinforcement.
- the son or fibers constituting the reinforcing layer are fixed to each other, which facilitates guiding and penetration of the reinforcing elements in the pultrusion die.
- disjoint weft yarns and disjoint warp yarns are intertwined forming loose stitches, and are bonded to each other by gluing at their junction points.
- the advantage of a grid-structured reinforcing layer is to ensure both good mechanical strength in the longitudinal direction and in the transverse direction, and to benefit from the very low cost of producing such a grid.
- the fibers forming the reinforcing layer may advantageously be continuous glass strands, which may have an individual linear weight of 68 tex to 272 tex.
- roving can be used for continuous son of glass, said locks having a linear wick weight of 320 to 1200 tex.
- the textile reinforcement according to the invention may comprise the superposition of a first surface layer of fiber web forming a first external face of the textile reinforcement, followed by a first layer of thickness based on said sections of glass fibers coated with polyester binder, itself followed by a reinforcing layer forming a second outer face of the textile reinforcement.
- the textile reinforcement according to the invention may comprise the superposition of a first surface layer of fiber web forming a first outer face of the textile reinforcement, followed by a first layer of thickness to base of said fiberglass sections coated with polyester binder, itself followed by a first reinforcing layer, followed by a second thick layer based on said fiberglass sections coated with polyester binder, itself followed a second reinforcing layer.
- the surface layer or layers of fiber fleece may be of polyester, polyamide, or polypropylene, being observed that they consist of a material whose melting temperature is greater than that of the polyester binder ensuring the connection of the layers of the textile reinforcement, for example a melting point of the order of 250 ° C.
- the sections of glass fibers may advantageously have a length of 40 to 120 mm. A good compromise is thus achieved between the ability of the fibers to be oriented in all directions randomly within the textile reinforcement, and the ability of the fibers to confer a high mechanical strength to the textile reinforcement.
- the sections of glass fibers are in an amount of 150 to 2000 grams per square meter.
- the polyester binder may be in an amount of 3% to 5% by weight of the glass fibers.
- the present invention proposes a process for manufacturing a textile reinforcement that can be used for the production of composite parts by pultrusion, comprising the following successive steps:
- step f provision can be made for:
- the first web may advantageously be obtained by carding, and have a basis weight of 20 to 40 grams per square meter.
- the polyester resin used to make the thickness layer may be an unsaturated, soluble or styrene-insoluble bisphenolic polyester resin, and in an amount of 3% to 5% by weight of the fiberglass sections.
- the polyester resin used in the thickness layer can have the property of melting when subjected to a temperature of 100 ° C for two minutes.
- the polyester resin may be in the form of a dry powder or in the form of a powder emulsion in water.
- polyester web or sails used to make the outer surface or surfaces may advantageously be colored, giving the reinforcement, and then the pultruded material made from the reinforcement, a color in the mass, resistant to external aggressions, without require additional coloration of the pultruded material itself.

- heating of the resin can be provided by infrared whose efficiency is not disturbed by the presence of a reinforcing layer, itself deposited after heating.
