Definitions
- the present invention relates to a network of parallel glass wires intended to serve as reinforcement of an organic mixture.
- Glass strands can be used in a variety of ways to strengthen thermosetting or thermoplastic organic materials.
- a composite part, obtained from such reinforced materials is mechanically stressed during its use, it is known to produce said piece from glass son oriented in a direction privileged. Often this type of part is made by impregnating several organic matter layers of glass strands in the form of unidirectional layers.
- the second difficulty lies in the production of a complex composite part, in which the reinforcements arranged in parallel are oriented in a plane along at least two different directions to follow the shape of said piece.
- a complex composite part in which the reinforcements arranged in parallel are oriented in a plane along at least two different directions to follow the shape of said piece.
- Such a part requires the juxtaposition of at least two parallel reinforcing plies in two orientations different.
- This distribution of reinforcements results in a discontinuity when passing from a tablecloth to another. If the area in which this discontinuity is located, let it be on the surface or within the composite material, is subjected to efforts, over-stresses will appear in this area with the consequence of the risk of rapid degradation of the material.
- the different orientations of the reinforcement plies also induce over-stresses over the entire periphery of the composite material part.
- the subject of the present invention is a network of parallel glass wires such as said wires can be used as reinforcements in a complex composite part, avoiding any discontinuity within said part.
- the subject of the present invention is a network of parallel wires capable of being deformed and which has sufficient stability to be handled without risking causing accidental displacement of one or more wires during the production of a composite part complex.
- the subject of the present invention is a network of parallel glass wires in which the method of bonding said wires together is such that it practically does not affect the resistance to fatigue of a composite part in which said network serves as reinforcement.
- the present invention also relates to a composite material reinforced by a such a network of parallel glass wires.
- a network of parallel glass wires intended to be associated to an organic mixture to produce a composite material, said network being formed of a multiplicity of continuous glass strands, arranged in parallel in the form of a flat sheet, said wires being connected to each other by wires arranged transversely to said sheet according to a binding method called chain, the glass strands being made partially integral by means of an organic thermoplastic binder, and the binding yarns having a module lower elasticity than glass wire and a melting or softening temperature higher than the melting or softening temperature of the binder.
- the quantity by weight of organic matter deposited is generally higher at 0.5% relative to the weight of the sheet and, preferably, less than 2%.
- the binder is deposited at a temperature below its softening temperature or of fusion and reheated on the surface of the water table to a temperature higher than its point softening or melting to ensure adhesion of the binder to the surface of the web.
- softening means the transition from the solid phase to a sufficiently viscous phase to ensure adhesion of the binder to the web.
- the softening or melting temperature of the binder chosen is generally greater than approximately 40 ° C and less than approximately 130 ° C.
- consolidation is meant a state such as intrinsic characteristics of the network of parallel glass wires and of the deformed sheet are not altered by successive manipulations.
- One of the advantageous characteristics of the glass wire network according to the invention is its ability to be able to deform, for example in a plane, so as to bend, in a zone determined the orientation of the glass strands constituting the sheet.
- This change orientation is carried out, for all of the ply yarns, relative to one of the yarns transverse which link said wires.
- these cross wires will be referred to in the continuation of the description son of binding.
- the geometrical deformation of the network of parallel glass wires must occur at a temperature above the softening or melting point of the binder.
- the wire network of glass thus deformed, after returning to a temperature below the temperature of softening or melting of the binder, also presents a state of consolidation such that its handling is greatly facilitated and its deformation geometry easily preserved.
- the tying yarns used consist of a material whose melting point or softening is higher than the melting or softening temperature of the binder. So can the network be deformed and consolidated by cooling several times without ever lose the orientation potential of the wires passing through the loops of the chain.
- the method of tying the wires of the web of the network according to the invention is a chain and, preferably a closed chain link. This method of tying by a chain allows son of the glass sheet to be maintained within it, stretched and without ripples which allows to considerably increase the fatigue strength of a composite material consisting of such a reinforcement.
- this method of tying makes it possible to maintain a constant and defined spacing between the glass strands of the sheet in order to ensure good flow of the organic resin to the within the reinforcement during the molding phase to obtain the composite material.
- this method of binding makes it possible to avoid any risk of random movement of the strands of glass strands during the molding phase when the injection or compression pressure becomes high, which improves the reproducibility of molded parts.
- the yarn chosen as the tying yarn or chain is preferably an organic yarn.
- the tying thread or chain may be made of an identical material or similar.
- the ability to deform the network of glass strands according to the invention is closely dependent on the interval separating two consecutive tying threads or chains. To get an inflection of the ply of wires parallel in a plane, without causing folds or corrugations, it is preferable that the smallest interval between two tying threads consecutive is at least equal to 5 millimeters. Binding wires in a wire network according to the invention are generally regularly spaced.
- the glass wires can be distributed in the sheet under the form of a series of locks, each lock being formed by the union of several wires.
- the wicks forming the sheet have a titer of at least 300 tex.
- the network of wires according to the invention is used to reinforce organic materials thermosetting or thermoplastic.
- the composite material produced comprises at least a layer of such a network.
- the layer or layers of threads which reinforce it may each consist of a network according to the invention, the web of which is deformed by relative to at least one tying thread, so that the threads are divided into at least two groups of parallel wires making a determined angle between them. So the composite material may include one or more plies of parallel wires which, after one or more deformations, remained flat. Each deformation then simply consisted of a rotation in the initial plane of each thread or wick around the different chain points a specific binding wire.
- the composite material can also comprise one or more plies which, after one or more deformations, have a curvature, a bend with respect to the initial plane of the tablecloth.
- Each deformation then consisted of a rotation of each wire or wick around at least one binding wire, chosen as the deformation axis, so as to form a angle determined with respect to the initial plane of the water table.
- the network of parallel wires according to the invention thus makes it possible to produce three-dimensional composite parts of shape complex.
- This figure schematically represents a fragment of a network of glass wires according to the invention.
- This network consists of a series of roving strands 10 arranged in parallel to each other in a plane.
- Each wick has a title of 1200 tex and it is made up of filaments with an average diameter of around 17 micrometers.
- the strand of wicks 10 is held in place by a closed chain 11 made of a polyester thread with a count of 50 dtex.
- the locks 10 are linked together by said chain using a loom of the knitting type. discarded stitches.
- the interval "d" between two consecutive chains is 8 millimeters.
- this network can be deformed in relation to the chain 12.
- the locks 10 have pivoted by an angle ⁇ using the loops of the chain 12 as hinges.
- This change of orientation is carried out without training of fold or ripple of the web.
- the same network can be distorted compared to several chains to follow complex shapes. Thanks to this great flexibility, the network according the invention can play the same role as several juxtaposed and oriented tablecloths differently, but without showing any discontinuity at one end of the ply of yarns glass to another.
- a flat plate, curved at its two ends, 70 cm long by 10 cm of width was made by stacking 10 layers of a network of strands of glass threads such as defined above.
- Each layer is formed by a network of strands of threads on which has been deposited beforehand a powdered thermoplastic binder.
- This binder deposited at a rate of 1% by weight of glass is a polyester marketed under the reference NEOXIL 940 HF-2B by the Company DSM.
- the network deformation is consolidated by cooling, after treatment thermal at 80 ° C.
- the stack produced was impregnated with a resin constituted by a system marketed by THE DOW CHEMICAL Co under the trademarks D.E.H. 39 and D.E.R. 332.
