Definitions

  • This invention generally relates to multilayer fabrics, and more particularly to integrated multilayer fabrics having a prescribed integration pattern formed of winding yarns arranged in a plurality of layers at prescribed angles bound together by a set of through-the-layers binder yarns, and an apparatus and method of fabricating same.
  • Integrated multilayer fabrics have wide applications such as advanced composites, power transmission and conveyer belts, fabrics in paper forming machines, among others.
  • Advanced composites include high performance fibers in a matrix. Depending on the fibers and matrix materials and manufacturing parameters, advanced composites offer superior strength-to-weigh and modulus-to-weight ratios, fatigue strength, damage tolerance, tailored coefficient of thermal expansion, chemical resistance, weatherability, temperature resistance, among others.
  • Fibers are the basic load-bearing component in a fiber reinforced composite. They are often pre-assembled into various forms to facilitate the fabricsation of composite parts. Advanced composites are often made from prepreg tapes, sheets and fabrics that are parallel continuous fibers or single-layer fabrics held by a matrix forming material. They are used to make parts by laminate layup and tape or filament winding. The traditional laminated composites are vulnerable to delamination because the layers of strong fibers are connected only by the matrix material that often is much weaker than the fibers. The introduction of fiber reinforcement in the through-the-thickness direction in a three dimensional composite could effectively control delamination failures and make the composite very damage tolerant. Besides performance enhancement, composites reinforced with integrated fiber structures may also offer other advantages such as the potential for automated and net shape processing and lower manufacturing cost.
  • Fully interlocked and adjacent layer interlocked three dimensional fabrics may be formed by weaving or braiding.
  • the yarns are crimped due to yarn interlacing or intertwining, and the yarn crimps in the fabrics cause a reduction in the stiffness and strength of the composites reinforced with such fabrics.
  • the fabrics layers are integrated by interlocking, there are no reinforcing yarns placed directly in the through-the-thickness direction.
  • Multilayer fabrics having layers of parallel fibers at predetermined angles bound by a knitting process are also commonly used in reinforced composites. Methods of making such multilayer fabrics are disclosed in U.S. Patent No. 4,518,640 to Wilkens . These methods are suitable for making flat fabrics with fixed yarn orientations.
  • the in-plane layers normally include high performance fibers such as glass and/or graphite fibers, whereas the knitting yarns generally are made of flexible fibers such as poly(ethylene terephthalate) (PET) or aramid rather than using the same type of high performance fibers as in the in-plane layers.
  • PET poly(ethylene terephthalate)
  • aramid rather than using the same type of high performance fibers as in the in-plane layers.
  • Fabrics with solid rectangular or other cross sectional shapes such as I and T sections may be constructed with reinforcing fibers in both in-plane and through-the-thickness directions by three dimensional weaving and braiding processes, as disclosed in, for examples, U.S. Patent No. 4,312,261 to Florentine and U.S. Patent No. 5,085,252 to Mohamed et al. These processes are generally limited in the dimensions of the fabrics that can be produced.
  • Tubular fabrics may be constructed with reinforcing fibers both in the circumferential layers and in the through-the-thickness direction, as disclosed in, for example, U.S. Patent No. 4,001,478 to King and U.S. Patent No. 4,346,741 to Banos et al. Such processes do not afford the flexibility of changing the fabrics geometry and yarn orientation at different locations in the fabrics as needed.

  • Each shuttle guide is provided with plural stages of guiding channels extending in a direction perpendicular to the radial direction radiating from the center material. The height of the guiding channels are made to be successively lowered to form a spiral path.
  • US5091246 (A ) shows a three dimensional fabric of substantially columnar shape having an axis.

  • a plurality of binder yarn insertion needles 340 insert the binder yarns 342 through the layers of winding yarns 330 to form open loops defined by the folded binder yarns such that a holding yarn 371 may go through the loops to lock the binder yarns 342.
  • An auxiliary bar may accompany each binder yarn insertion needle 340 to keep the binder yarn loop open while the holding yarn 371 is inserted, and to help tightening the binder yarn 342 after the holding yarn 371 is inserted while limiting the bending curvature in the binder yarn 342 as it is tightened.
  • a knitting mechanism including a needle and yarn feeder forms a loop of the holding yarn which goes through the open loop of the folded binder yarn.
  • the purpose of the holding yarn 371 is to hold the binder yarn 342 in place in the fabrics 312, and to prevent the binder yarn 342 from being pulled out as the binder yarn insertion needle 340 retreats and the slacks in the binder yarn 342 is removed.
  • the sequence of forming holding yarn loops to lock the binder yarn is as follows, with steps (a) to (d) illustrated in Figs. 3-6 , respectively:
  • the holding yarn insertion mechanism moves circumferentially to the next binder yarn location, and steps (c) and (d) are repeated until all the binder yarns 341 are locked and tightened.
  • the mandrel carrying the fabrics advances upward for fabrics take-up.
  • the mandrel carrying the finished fabrics moves upwards such that the holding yarn (or binder yarn if holding yarn is not used) loops will be on the outer surface of the fabrics.
  • the mandrel and the fabrics can move through the shaping ring downwards such that the loops formed by the holding yarn (or binder yarn if holding yarn is not used) appear on the inner surface of the fabrics.
  • the insertion and locking of each binder yarn by the holding yarn at any given point can be executed or omitted via the control system, and therefore the integration pattern can be altered as desired even within the same piece of fabrics.
  • Fig. 7 shows an example of tubular fabrics with a [45/-45/0/90/-45/45] layup, according to one embodiment of the present invention, where the ply orientations from inner surface to outer surface are given in degrees.
  • Fabrics of various cross sectional shapes may be formed according to the above disclosed method. Some of them are illustrated in Fig. 8 as examples. Besides capable of making cylindrical tubular structures (a), many variants are available to produce fabrics with different cross sectional shapes and varying cross sectional shapes along the length.
  • the mandrel can be noncircular in shape to produce fabrics having noncircular cross sections such as those depicted in (b) and (c).
  • the size or shape of the cross-sectional of the fabrics can also vary along the length, such as (d).
  • a mandrel is not use but a shaping mechanism is used instead so as flat (e) or other shaped sections (f) can be produced.
  • a flat sectioned panel can also be made by cutting open a tubular fabric (a), and a T-section (f) can be formed by collapsing tubular fabric (a).
  • a tubular fabric a
  • a T-section f
  • a discontinuous layer may be laid.
  • a single or a plurality of such discontinuous layers manifests themselves as ribs of the fabrics (g).
  • the width, height, and interval of the ribs may be varied as required.
  • the ribs may be on the outer, inner or both faces of the fabrics.
  • Flat sectioned fabrics with ribs may be obtained by cutting open a tubular ribbed fabric (g).
  • Fabrics with varying wall thickness within a cross-sectional (i) can be made by changing the amount of axial (0 degree) yarns at different cross sectional locations, by placing incomplete layers of winding yarns, or both.
  • the present invention recites an apparatus and method for fabricating integrated multilayer fabrics with the winding yarns arranged in a plurality of layers at prescribed angles bound together by a set of through-the-layers yarns.
  • the integrated multilayer fabrics can be tailored to have a variety of constant or variable cross sectional shapes, constant or variable fiber orientation and integration patterns according to requirements for local fiber architecture and fabrics geometry.
