  • Pultrusion refers to a process for producing continuous fiber composite profiles.
  • Pultrusion is a desirable method to make composites because pultrusion is a continuous process.
  • the process consists of pulling continuous fibers (glass, carbon, aramid or other) through a die, impregnating them with a matrix resin and forming the resin and fibers to a final cross sectional shape.
  • thermoset resin matrix such as polyester, vinyl ester, epoxy, or phenolic. More recently resins and processes have been developed to produce pultrasions with thermoplastic as the matrix resin. Examples include 'Fulcrum' (Edwards et al - 6,165,604 & 5,891,560), PVC plastisols, cyclic butylene terephthalate, polybutylene terephthalate, co-mingled fibers of polypropylene, PET and other resins, production of thin tapes or rods with other polymers which are subsequently consolidated to a larger profile and others.
  • the composite is relatively weak, brittle and flexible across its width and has a tendency to split as wood does, along the grain, especially when the section thickness is small compared to the overall dimensions. Also, such composites tend to have relatively low torsional, shear and buckling properties.
  • thermoset composites these difficulties are overcome by using various means to provide off-axis fibers in the profile. These means include: drawing layers of non-axial fibers into the die along with the axial fibers. These layers may be woven cloth or mat, random fiber mats, stitched mats, etc. Another means of overcoming the low off-axis properties, especially in producing thin-walled hollow tubes, is to wind continuous fibers in a shallow spiral in between layers of axial fibers ('pullwinding'). These alternatives, to an extent, overcome the problem of low off axis and shear properties in thermoset composites, but are difficult to apply when manufacturing thermoplastic composites. Also even in thermoset composites such approaches are not completely satisfactory because they add cost and complexity to the process and are limited in how and where they can be applied.
  • thermoset and thermoplastic composites are formed from thermoset and thermoplastic materials. If it is necessary to cut the surface of the composite, for example to tap a thread onto the surface of a rod, then in doing so the continuous fibers are cut. Once cut, the local strength of the composite is dramatically diminished. Also the chemical resistance of the composite is compromised because in the area of the cut the ends of the fibers are no longer protected by the matrix and are exposed to chemical attack.
  • thermoset composites It would be desirable for pultrusions to have a means of enhancing the off-axis properties of the composite which do not have the limitations of the existing techniques known for thermoset composites.
  • the instant invention describes a means of overcoming the current limitations by, for example, pultruding thermoplastic composites using existing techniques while either simultaneously or subsequently combining the pultrusion with a second thermoplastic composite containing substantially randomly dispersed discontinuous reinforcement fibers.
  • the second, substantially random fiber filled component is positioned either within or external to the continuous fiber component to provide off-axis properties in the position most beneficial to the desired structural properties.
  • the substantially random fiber filled component ideally has a matrix resin which is similar to and compatible with the matrix resin of the continuous fiber component.
  • the substantially random fiber component can be incorporated directly by feeding from an extruder into directing slots in the same die that produces the continuous fiber component, or can be extruded onto or around the continuous fiber component after it exits it's own die or can be injection or compression molded in a single or multiple shots around the continuous fiber component in a subsequent operation.
  • a further advantage of this aspect of the instant invention is that, unlike the use of off-axis fiber mats in existing pultrusions, the random fiber thermoplastic compound can be varied in thickness and position more readily.
  • a particularly advantageous type of random fiber filled composite is so called long fiber filled thermoplastic compounds of the type manufactured by Ticona, RTP and GE/LNP companies. These compounds are distinct from other fiber filled compounds in that the fiber length in the granules is typically 12 mm (though it may vary from 6 mm to 100 mm) while conventional fiber filled compounds have shorter fibers, typically less than 6 mm. This additional fiber length imparts enhanced properties particularly desirable in enhancing the off axis properties of the continuous fiber composite.
  • Typical fiber content for these compounds ranges from 30 to 60% by weight, but may range from 10 to 75% by weight of fiber.
  • the long fibers When overmolded or overextruded in relatively thin sections, the long fibers become aligned within the thickness of their plane while remaining more random across and along the plane.
  • the random dispersion and random direction of these fibers gives properties which are more homogenous and less anisotropic than the continuous fiber component.
  • Such reduced anisotropy while giving the material significantly lower properties in the longitudinal direction than the pultruded composite, results in significantly higher properties in all other directions making the second discontinuous random fiber filled component much more suited to carry loads in all directions other than longitudinal, including shear and torque loads.
  • Another aspect of the instant invention is that it provides a means to provide regular or individual protuberances on the surface of the composite having at the same time improved mechanical properties.
  • One form of these protuberances is threads so as to create a continuously threaded rod.
  • the threaded rod has enhanced torsional and thread shear properties as a result of the substantially random alignment of the reinforcing fibers.
  • a second form is to create features on the surface of the continuous fiber composite profile which are useful in the functional performance or assembly of articles manufactured from the composite profile.
  • these features may be local features to provide strengthening in areas of high load or stress such as areas in which it is necessary to drill a hole in the continuous fiber composite.
  • they may be fastening features molded onto the continuous fiber composite profile to facilitate joining to other articles.
  • one or more shapes are pultruded by pulling rovings of continuous fibers into a die into which, for example, molten thermoplastic resin is also fed.
  • the continuous fibers are impregnated and wetted out by the thermoplastic and forced into the desired shape by pulling them through a portion of the die which has that shape.
  • a second thermoplastic polymer containing substantially randomly dispersed discontinuous fibers is introduced into the die.
  • the second thermoplastic in this embodiment of the instant invention is chosen to be chemically compatible with the first.
  • the second thermoplastic is directed through slots in the die to shape it and bring it into contact with the pultruded sections.
  • the resultant total profile consists of portions of the profile in which the material is thermoplastic with continuous unidirectional fibers along its length and portions in which the material is thermoplastic with discontinuous fibers substantially randomly oriented.
  • substantially randomly oriented means not only true random orientation, but also some degree of orientation that occurs during the molding operation, but not the essentially longitudinal orientation of the continuous fiber composite.
  • the matrix of the continuous fiber composite and/or the matrix of the substantially random fiber composite can comprise a thermoset polymer.
  • the matrix of the continuous fiber composite and/or the matrix of the substantially random fiber composite comprises a thermoset polymer
  • the second composite is introduced before the first composite has fully cured.
  • the second preferred thermoplastic component, containing the substantially randomly oriented fibers can alternatively be combined with the continuous fiber pultruded shape(s) in a second die after the shape(s) exit the first die. This produces the same kind of combined profile containing portions of continuous and random fibers. This method can have the advantage of simpler dies.
  • the second preferred thermoplastic component containing the discontinuous substantially randomly oriented fibers can be combined with the continuous fiber pultruded shapes in a molding operation performed either in-line with the pultrusion or offline after the pultrusion of the continuous fiber composite is complete. Again this produces the same kind of combined profile containing portions of continuous and random fibers.
  • This variation of the process has the advantage that the shape of the portion containing discontinuous fibers is no longer limited to being two dimensional. For example, repeating features such as threads can readily be incorporated. It will be appreciated that in addition to the profile having fiber architecture suitable to resist the applied loads it is also beneficial to have an excellent bond between the two components.
  • this bond is created as a result of the heat and pressure of the process and the chemical compatibility of the two preferred thermoplastic portions.
  • the bond between the two components may be further enhanced when molding the second thermoplastic component, by using the heat and pressure of the molding operation to deform the first component, such that a mechanical interlock or undercut is formed between the two components. This can be done continuously as described above or in discrete sections of overmolding.
  • the proportion of continuous fibers to discontinuous fibers within the profile may vary in any desired proportion, but preferably is from 90% continuous aligned fibers, 10% discontinuous random fibers to 10% continuous aligned fibers, 90% discontinuous random fibers.
  • the positioning and proportions of the continuous and discontinuous portions within the profile is determined by the required properties of the profile.
  • the amount and position of the discontinuous fibers is determined by the required resistance of the profile, both globally and locally to shear, torque and bending loads perpendicular to the axis of the profile.
  • a simple rectangular profile 10 comprising layers 11 consisting of random fiber composite and layer 12 consisting of continuous fiber composite.
  • Fig. IB therein is shown a simple rectangular profile 13 comprising layers 14 consisting of continuous fiber composite and layer 15 consisting of random fiber composite.
  • a tubular profile 16 comprising layer 17 consisting of random fiber composite and layer 18 consisting of continuous fiber composite.
  • Fig. 2B therein is shown a simple tubular profile 19 comprising layer 20 consisting of continuous fiber composite and layer 21 consisting of random fiber composite.
  • the profile would have better resistance to torsional loads, buckling or splitting but lower bending properties while in Fig. 2B the profile would have better bending properties but less torsional resistance.
  • FIG. 3 A therein is shown an "I" beam profile 22 wherein region 23 consists of random fiber composite and region 24 consists of continuous fiber composite.
  • FIG. 3B 5 therein is shown another “I” beam profile 25 wherein region 27 consists of random fiber composite and region 26 consists of continuous fiber composite.
  • Fig. 3C therein is shown yet another “I” beam profile 28 wherein region 30 consists of random fiber composite and region 29 consists of continuous fiber composite.
  • “I" beams are designed to resist bending. The top and bottom flanges contain a large proportion of the total section and are placed as far as practically possible from the neutral axis.
  • Figs 3A, B and C represent various options for how to utilize the continuous fiber composite to resist tension and compression in the flanges while using the random fibers to resist shear in the web.
  • a threaded rod profile 31 wherein region 32 consists of random fiber composite while core 33 consists of continuous fiber composite.
  • FIG. 4B therein is shown another threaded rod profile 34 wherein region 35 consists of random fiber composite while inner tubular portion 36 consists of continuous fiber composite.
  • threaded rods must resist both torque and tension.
  • the outer layer of material is most effective in resisting torque so substantially random fibers are usually best utilized here.
  • the tensile load is carried by the uni-axial core, either solid, as shown in 4A or hollow tube as shown in 4B. In threads a further critical load must be resisted; the force from the mating thread which tends to shear off the threads themselves.
  • FIG. 5A therein is shown Figs 5A, a bolt 37 wherein the head, shaft and threads are overmolded in a substantially random fiber thermoplastic 38 onto a solid rod of thermoplastic composite with continuous longitudinal fibers 39.
  • the random fibers in the overmolding provide higher shear strength in the head and threads than would be obtained by machining the bolt from a solid piece of composite with longitudinally aligned fibers.
  • a bolt 43 where the head shaft and threads are overmolded of a random fiber composite 44 onto a tube 45 consisting of continuous fiber composite.
  • the tube is preferably supported internally during the molding operation to prevent it from tending to collapse under the heat and pressure of the overmolded component.
  • a bolt 40 wherein the head shaft and threads are overmolded of a random fiber composite 41 onto a tube of continuous fiber composite 42, but in this instance the mandrel supporting the tube is tapered from each end so that the heat and pressure of the overmolding material cause the tube to constrict and be thermoformed onto the mandrel creating an undercut which increases the tensile strength of the bolt by resisting the tensile force which may otherwise pull the head off the bolt.
  • EXAMPLE l Thermoplastic composite rods of 16.9 mm diameter are pultruded using the process described in Edwards et al - 6,165,604 & 5,891,560 with a matrix of Rigid Thermoplastic Polyurethane (RTPU). The rods are subsequently over molded using a Long Glass Filled RTPU containing 40% by weight of fibers of 12 mm length (LGF RTPU) to produce a continuous 25.4 mm threaded rod. Additionally samples of threaded rod are prepared by molding only, without the core of uni-directional composite.
  • RTPU Rigid Thermoplastic Polyurethane
  • thermoset threaded rod samples Upon failure it is noted that all of the thermoset threaded rod samples fail as a result of the threads on the rod being sheared by the forces from the nut.
  • the thermoplastic samples without the unidirectional core fail in tension at a very low load.
  • the thermoplastic samples with the unidirectional core show a mixed failure mode with some samples failing by breaking the bond between the over molded composite and the pultruded core while others fail by stripping the threads on the nut without breaking the threaded rod. This indicates that somewhat higher values may well be obtained if a stronger nut is used.
  • thermoplastic composite rod of 6.4 mm diameter is pultruded using the materials and process described above. Rods are subsequently over molded using: 1) a Long Glass Filled rigid thermoplastic polyurethane containing 40% by weight of fibers (LGF RTPU); and 2) a Long Glass filled nylon 6/6 containing 35% by weight of fibers (LGF PA). Both fibers are of 12 mm length to produce a continuous 12 mm threaded rod. Samples of commercially available threaded rods produced by pultruding a thermoset composite and cutting threads of the same dimensions are obtained and all samples are subjected to tensile testing as described in Example 1. The force to break the specimens is recorded. The maximum and minimum values obtained are recorded below.
