  • ABSTRACT Primary ExaminerWilliam D. Martin Assistant ExaminerShrive P. Beck Attorney, Agent, or Firm-Craig & Antonelli [5 7 ABSTRACT A process for impregnating fiber strands, especially carbon fiber strands, and similar reinforcing fibrous materials having substantial length which comprises winding 2 carbon fiber strand off of a take-off means at a low take-off tension, impregnating the strand with the resin, and thereafter winding up the resin impregnated strand under a high winding tension.
  • Fibrous materials having a high tensile strength and a comparatively high modulus of elasticity (tensile strength 1,; up to 460 kp./mm modulus of elasticity E 7,000 to 2 10,000 kp./mm where kp. represents kiloponds) made of various glasses have been utilized for many years for plastic reinforcements in the form of mats, fabrics, rovings, etc.
  • a special method for the production of glass-fiberreinforced composite materials is the filament winding process.
  • rotational bodies can be manufactured in accordance with this procedure; the reinforcing materials used in this procedure are individual strands or rovings as well as roving ribbons of greater lengths.
  • matrix materials unsaturated polyester resins (UP) and epoxy resins (EP), are employed in many cases.
  • the carbon fibers to be employed are wound onto spools or take-off means in cross laps, i.e., at an angle of about 45 70 with respect to the longitudinal axis of the spool, in lengths starting with about 500-600 in. If the strand of carbon fibers is now taken off from the spool with a take-off force of about 500 ponds (the unit pond being a standard measure of force, otherwise known as a gram-force) and there above, it is unavoidable that the carbon fiber strand, wound in cross laps, can be considerably damaged during the take-off procedure.
  • This invention is characterized in that a take-off means, e.g., a spool, reel or the like, is positioned in a pivotable manner, namely at an angle corresponding to the windup angle of the strand of carbon fibers. Furthermore, since the take-off means is braked during the unwinding procedure, (so that a controlled small takeoff force is built up, which ranges advantageously between about and about 250 ponds), this invention ensures that the carbon fiber strand is gently taken off from the take-off means without exerting friction on the laps disposed therebelow and thus without damaging the fiber. This angular adjustment or orientation is maintained until the strand has reached one end of the take-off means.
  • a take-off means e.g., a spool, reel or the like
  • the take-off means is swiveled by photoelectric control means to such an extent that the strand, which now runs back on the take-off means in the direction of its longitudinal axis, is taken off from the wound-up coil in an extensively frictionless manner.
  • the take-off means is once again pivoted once the strand has reached the other end of the take-off means.
  • the dry strand of carbon fibers now travels over rollers to the first impregnating device or means.
  • This means includes a thermostatically controlled container having a capacity of about 300 to about 1,000 cc. which contains the impregnating resin that has been brought to the most favorable impregnating temperature.
  • the container or bath' contains a metallic roll immersed to about 2 to about 5 centimeters into the resin bath.
  • the carbon fiber strand travels, controlled by guide rollers from the take-off device, with a certain contact pressure over the impregnating roll, which, in turn, is set into rotation thereby. Due to this rotation, the impregnating roll conveys impregnating resin from the bath on its cylindrical outer surface.
  • a resin film is produced through which the strand of carbon fibers travels.
  • the thickness of the resin film is regulated by means of stripping plate or doctor blade means, e.g., by the provision of a displaceable stripping plate means between the resin level in the bath and of the carbon fiber strand traveling over the impregnating roller.
  • the thickness of the resin film to be selected is predominantly dependent on the viscosity of the impregnating resin at the predetermined temperature.
  • the strand of carbon fibers is guided over a second impregnating device or means, constructed similar to the impregnating device described previously.
  • the strand is advantageously conducted or transported in such a manner that the surface of the strand which is on top on the first impregnating roll contacts the second impregnating roll directly when traveling over this roll.
  • the thus-impregnated strand is now guided over sevcral guide or deflecting rollers (advantageously at least three) to the threading eye of the winding machine.
  • These guide rollers can be braked so that an adjustable maximum take-off force or filament tension can be built up in the impregnated carbon fiber strand.
  • This high winding force or filament tension is absolutely necessary for obtaining a uniformly constructed wound body wherein the distribution of fibers within the resin is as homogeneous as possible, i.e., wherein it is ensured that the filaments are impregnated with the resin without any air bubbles and in an extensively homogeneous manner, and conversely, the resin surrounds the strand in the same homogeneous manner, so that optimum property characteristics can be attained.
  • This invention is particularly directed to the combination of pivotable delivery spool or take-off means provided with a braking motor with two impregnating means and the braked guide rollers for providing a maximally attainable take-off force or filament tension.
  • Strands, ribbons, threads, tapes or the like fibrillary products of carbon fibers impregnated in this manner are particularly suitable for the production of wound articles in accordance with the known filament winding method, or for the manufacture of pre-impregnated carbon fiber strands and/or carbon fiber threads.
  • FIG. 1 shows an elevational view of an impregnating apparatus according to this invention.
  • FIG. 2 shows a swiveling device for the delivery spool.
  • the roller system is mounted on a vertically disposed mounting plate 3, the axes of all rollers being in parallel to one another, and forming a right angle with respect to the plate.
  • the strand of carbon fibers is conducted from the delivery spool or reel 2 over a first guide roller 4 arranged directly in front of the first resin impregnating roll 5. Thereafter, the strand is fed, by a second guide roller 6 disposed at a somewhat lower level, to a second resin impregnating roll 7. Both resin impregnating rolls 5 and 7 are immersed in resin baths 8, 80, respectively. These resin baths can be heated by thermostated heating baths 9, 90, respectively.
  • the layer thickness of the resin entrained from the resin bath by the rolls during rotation thereof is adjustable with the aid of the stripper plate or doctor blades 10 and 10a disposed directly in front of the rolls; the gap between the impregnating rolls and the stripper plates represents a measure for the layer thickness and saturation of the carbon fiber strand.
  • the guide roller 6 ensures that the carbon fiber strand, initially impregnated on one side by the roll 5, is also impregnated on the other side during contact with the second impregnating roll 7. By the pressure of the carbon fiber strand on the impregnating rolls, the rotation of the latter is effected.
  • the strand After being impregnated on the second resin impregnating roll 7, the strand passes over a series-connected guiding system consisting of a number of braking rollers 11 (in this case five rollers are used) through which the strand is conducted in an approximately sinusoidal path.
  • the braking force of the braking rollers can be adjusted, so that the carbon fiber strand can be wound up at the windup core 12 with a counter-tension of about 5 kp.
  • the spool swiveling device is described with reference to FIG. 2.
  • the cross-wound delivery spool 2 is mounted in the plane of the delivery of the fiber strand on the plate 15 to be pivotable about the pivot axis 14.
  • the delivery spool 2 is coupled, via a belt drive, with a variable-speed motor 16, likewise mounted on the plate 15.
  • the torque of the motor is adjustable.
  • the plate 15 is connected with an eccentric disk 18 via a lever 17 and the disk is set into rotation by a drive motor 19.
  • the eccentric disk is rotated by angle of whenever a pivoting of the delivery spool is necessary after winding off one layer of the cross-wound carbon filament strand 1, namely by the angle formed in each case by the fiber strand with the axis of the delivery bobbin.
  • the pivoting of the delivery spool 2 is controlled photoelectrically by means of reversing switches 20, 20a provided with a light contact.
  • the photoelectric control shown uses two light emitters installed on either side of frame (13) in FIG. 2. Each emitter has its own receiver mounted on a place opposed to it (not shown on the drawing). The emitter produces a light ray which is continuously received by its own receiver. Now if any object as for instance a strand enters the space between emitter and receiver, the latter no longer receives the light ray and interrupts an electrical circuit, thus giving a signal to activate the switch 20 or 20a to switch the driving motor of the spool swiveling device from forward to reverse.
  • the braking rollers 11 each employ conventional braking devices.
  • one filament carrying roller may be mounted on other side of the frame of the impregnating device,
  • the process and apparatus of this invention may also be used to impregnate reinforcing fiberous materials with various resinous materials including unsaturated polyester resins, epoxy-novolaks, epoxy resins hardened at elevated temperatures and epoxy resins hardened at ambient temperatures.
  • various resinous materials including unsaturated polyester resins, epoxy-novolaks, epoxy resins hardened at elevated temperatures and epoxy resins hardened at ambient temperatures.
  • control of the temperature of the impregnated resin in the baths is dependent on the choice of resin. For example it has been found that the temperature should be about 50C. for an epoxynovolak resin.
  • the process of this invention is especially suitable for impregnation of carbon fiber strands.
  • other reinforcing materials may also be processed.
  • the take-off tensions may vary from 0.01 through 5 kp and the winding tensions may vary between 0.1 and 20 kp, the tension being controlled in each case to depend on the fiber employed and the product desired.
  • a process for the impregnation of carbon strands having substantial length which process comprises winding carbon fiber strands off of a pivotal take-off means at a low take-off tension by controlling the take-off force to minimize damage to the carbon fiber strand,
  • control of the take-off force is by braking said take-off means.
  • low take-off tension has a minimum value such that friction is prevented from being exerted between respective laps of said carbon fiber strand disposed on said pivotable take-off means.
  • a process for the impregnation of carbon strandshaving substantial length which process comprises winding carbon fiber strands off of a pivotal take-off means at a low take-off tension by controlling the take-off force to minimize damage to the carbon fiber strand,
  • the low take-off tension in said carbon strand is controlled to be in the range of about 50 to about 250 ponds.
  • a process for the impregnation of carbon strands having substantial length which process comprises winding carbon fiber strands off of a pivotal take-off means at a low take-off tension in the range of about 50 to about 250 ponds by controlling the take-off force to minimize damage to the carbon fiber strand, wherein the strand is cross-wound onto said take-off means and the takeff means is pivoted so that its longitudinal axis is at an angle approximately equal to the wind-up angle of the cross-wound strand on said take-off means whereby damage to the reinforcing fibers of said strand is avoided,
