Definitions

  • the invention concerns a method of forming preforms in the manufacture of fibre composites, according to which method textile structures in the form of monoaxial or biaxial laid-yarn fabrics are used as reinforcement material.
  • the laid-yarn fabrics are draped on a core and are injected with a thermosetting plastic or a thermoplastic material, alternatively are heated, when the fabric is made from thermoplastic hybrid yarns.
  • multiaxial laid-yarn fabrics are used, said fabrics serving as reinforcement material in the finished plastic body, which then forms a fibre composite.
  • the reinforcement material imparts to the body considerable strength properties, due to the excellent tensile strength that laid-yarn fabrics exhibit in all directions .
  • a drawback found in the multiaxial laid-yarn fabric is, however, its poor drapability, which restricts the dimensions of the projecting sections of the mould that is to be used, when the multiaxial laid-yarn fabric is placed inside or on the mould prior to the application of the plastics material.
  • Such a multi-layer fabric By advancing in superposed relationship several webs of such monoaxial laid-yarn fabrics, wherein the wefts extend at mutually different angles, it becomes possible to produce a multi-layer web which, after having been cut crosswise, forms a multilayer fabric.
  • This fabric may subsequently be used to manufacture a plastics-fibre composite in a moulding process.
  • a multi-layer fabric has the advantage over the above-mentioned prior-art multiaxial laid-yarn fabric in that it possesses excellent drapability properties, which means that it shapes itself well to the configuration of moulds having comparatively sharply protruding parts, without risking to crack or form folds.
  • the invention provides a novel method, which is a further development of the method referred to above and which exhibits additional advantages over that prior-art method.
  • the characterising features of the novel method are that the fabric material is applied on a core, which is an elongate body, in the form of bands or ribbons, said bands or ribbons being advanced at an angle relative to the core and to one another and being wound onto the core in overlapping relationship, by rotation of the core about its longitudinal centre axis and simultaneous advancement of said core in its longitudinal direction.
  • Fig 3 shows a variety of the winding-on shown in Fig
  • Fig 4 shows the structure resulting from completed winding-on of the ribbons onto the core according to Fig 3, and
  • Figs 5-7 show a number of laid-yarn fabrics having mutually different structures.
  • Fig 1 shows one embodiment according to which four ribbons 1, 2, 3 and 4 of monoaxial laid-yarn fabrics are being wound onto a core 5.
  • the ribbons 1, 2, 3, 4 are shown somewhat schematically, i.e. the drawing figure shows only the extension of the threads 6, 7, 8 and 9, respectively of the ribbons.
  • the threads 6 of ribbon 1 extend at an angle relative to the direction of advancement of the ribbon 1
  • the threads 7 of ribbon 2 likewise extend at an angle relative to the direction of advancement of its ribbon
  • the threads 8 and 9 of ribbons 3 and 4 respectively, extend at right angles to the direction of advancement of those ribbons 3 and 4, respectively.
  • the core 5 is illustrated in the drawing figure as an elongate parallepepidon body having a rectangular cross-sectional shape but it could of course be configured differently, e.g. having a round or square cross- sectional shape.
  • the core 5 is made from cellular plastics but could equally well be made from wood or metal, e.g. aluminium.
  • the core 5 is assumed to be rotational about its longitudinal centre axis in the direction of arrow 10, and also to be displaceable in its longitudinal direction upwards (or inwards) with respect to the drawing figure.
  • Fig. 3 illustrates an embodiment, which differs from the one shown in Fig 1 in the respect that ribbons 1 and 4 have changed places and in that the ribbons 2 and 3 are applied to the core 5 prior to ribbons 1 and 4.
  • This small modification produces a different structure in the finished multi-layer fabric, as appears from Fig 4.
  • the threads 7 of ribbon 2 will be the one located closest to the core 5 and will extend in the longitudinal direction of the core
  • the threads 8 of ribbon 3 will cross over the threads 7 of band/ribbon 2
  • the threads 9 of ribbon 4 will cross the threads 8 of ribbon 3 at right angles thereto
  • the threads 6 of ribbon 1 will be placed on top of the threads 9 of band/ribbon 4 and extend at right angles to the longitudinal direction of the core.
  • the inventive method makes it possible to alter the structure as well as the thickness of the multi-layer fabric formed on the core 5.
  • Such alterations may be effected for instance by altering the width of the ribbons 1, 2, 3, 4, by altering the thread count in the fabric, by altering the speed of advancement of the core in the longitudinal core direction, by altering the speed of rotation of the core 5, or by altering the winding angle of the ribbons 1, 2, 3, 4 onto the core 5.
  • biaxial laid-yarn fabrics the same multi-layer structure is obtainable but with a fewer number of ribbons.
  • Figs 5, 6 and 7, finally, show various examples of combinations of differently structured laid-yarn fabrics in order to produce a multi-layer fabric of identical character.
  • Figs 5b sandwiching the fabric of Fig 5b between the fabrics of Figs 5a and 5c, the fabric of Fig 6b between the fabrics of Figs 6a and 6c, and the fabric of Fig 7c between the fabrics of Figs 7a and 7c, multilayer fabrics of identical structure are produced.

Abstract

L'invention concerne un procédé de formage de préformes pour la fabrication de composites de fibres, comprenant des toiles à fils orientés de manière monoaxiale ou biaxiale, qui sont injectés conjointement avec un plastique thermodurcissable ou un matériau thermoplastique ou - si la toile est constituée de fil hybride thermoplastique - sont chauffés. Selon le procédé de l'invention, on applique le matériau en toile sur une âme (5), qui est un corps allongé se présentant sous forme de rubans (1, 2, 3, 4). On fait avancer ces derniers selon un certain angle par rapport à l'âme (5) et on les enroule sur celle-ci de manière qu'ils se chevauchent, de préférence en faisant tourner l'âme (5) autour de l'axe de l'âme centrale longitudinale, pendant qu'on fait avancer ladite âme simultanément dans le sens de la longueur.
