Definitions

  • thermoset epoxy matrix A further need to apply relatively high pressure as well as provide mandrel rotation during said tension winding process requires robust and expensive mandrels together with significant,- mandrel handling labor.
  • continuous glass fibers in a thermoset epoxy matrix are employed.
  • Still other manufacturers produce a reinforced thermoplastic pipe construction having the thermoplastic pipe member as an innerlayer which is surrounded by various outerlayers of the reinforcement material.
  • one such manufacturer surrounds the thermoplastic liner with a fiberglass layer in an epoxy resin matrix and provides an exterior protective layer thereover of a still different fiber material which is again contained in an organic polymer matrix.
  • thermoset polymers in the reinforcement of a thermoplastic pipe member frequently creates additional manufacturing problems. The curing required of these polymers occasions contamination as well as time delay and these materials are not recyclable.
  • such controlled directional orientation of the continuous fiber component in the reinforced thermoplastic pipe member enables the fiber placement to be fixed for such maximum effectiveness since the fiber materials being employed are generally stronger than the thermoplastic polymers forming the pipe member.
  • the fiber reinforced end product is thereby only as strong as the spatial direction of the applied fibers with respect to the direction of the external stress when applied to said reinforced pipe member.
  • the applied load is withstood primarily by the included fibers and the strength of said pipe member is at maximum value.
  • the composite member is stressed in a perpendicular direction to the fiber direction, the applied force must necessarily be resisted primarily by the polymer pipe member so that pipe strength is at a minimum.
  • thermoplastic pipe member It is an important object of the present invention, therefore, to provide a more effective means for the fiber reinforcement of a thermoplastic pipe member in a continuous manner.
  • Suitable thermoplastic organic polymer materials forming the pipe member in the present composition construction include but are not limited to polyethylene such as high density polyethylene and medium density polyethylene, polypropylene, polyphenylene sulfide, polyetherketoneketone, polyamide, polyamideimide, and polvinylidene difloride.
  • a wide variety of materials are found suitable as the fiber reinforcement in the present processing procedure to again include but not be limited to ceramics, metals, carbon, aramid and other polymer fibers having softening temperatures above that of the pipe service temperature in use and glass compositions such as E type and S type glass.
  • the present thermal bonding of continuous fibers after having been wrapped in an unbonded condition about the outer periphery of the thermoplastic pipe length or lengths involves an operative cooperation between the applied fibers and the outer surface of said pipe member.
  • a softening or melting action takes place during the thermal bonding step between the outer surface of the thermoplastic pipe member and any thermoplastic polymer materials serving as the matrix composition in selected preformed tape embodiments having the continuous reinforcement fibers bonded therein.
  • the applied fibers become physically joined to the pipe member with softened or melted thermoplastic polymer when the fiber wrapped pipe member is heated in the present method such as occurs when melting said outer pipe surface.
  • the present continuous method necessarily further includes provision being made for both start-up as well as termination and possible process interruption.
  • Satisfactory start- up of the present processing procedure can be conducted in various ways to include starting with a single thermoplastic pipe length or multiple pipe lengths and feeding these members with continuous linear motion at a relative constant velocity to suitable fiber winding means.
  • a continuous thermoplastic pipe length can be suitably provided employing conventional extruder means while the feeding of discrete pipe lengths to the operatively associated fiber winding means can preliminarily involve having the discrete pipe lengths simply butted together physically in an in-line configuration as well as having the respective pipe ends fused or welded to each other.
  • thermoplastic pipe member Conventional means can be employed for continuous transport of the thermoplastic pipe member during processing in said manner including known moving belt drive mechanisms and motor driven rollers. Suitable start-up would also optionally include having the initial continuous fiber being physically secured to the outer surface of the first moving thermoplastic pipe member being processed with conventional clamping or adhesive bonding means. Following a continuous thermal bonding of the applied reinforcement fibers in the manner previously described, the present method can be terminated with conventional cut-off means being employed to suspend any further fiber placement. Satisfactory cut-off means can utilize a moving cutter device traveling in the same linear direction as the moving pipe member or members and to include a cutter severing the pipe along with the applied fiber reinforcement. Novel apparatus means are employed to provide continuous fabrication of the present fiber reinforced thermoplastic pipe member.
  • the reinforcement fiber comprises a plurality of the selected continuous length juxtapositioned fibers being supplied from a rotary spool 24 operatively associated with said winder mechanism and which feeds the supplied fiber material at a relatively constant rotational speed.
  • said first wrap or ply of the fiber reinforcement has been applied in an unbonded condition at a predetermined spatial angle with respect to the longitudinal axis of the moving pipe length in response to a counterclockwise rotation of drum member 20.
  • the particular reinforcement fiber material 22 being applied in the illustrated embodiment consists of continuous length glass filaments embedded in a thermoplastic polymer matrix but still other commercially available prepreg or preformed reinforcement tapes of similar construction are deemed equally suitable for processing in the illustrated apparatus.
  • FIG 2 there is shown schematically in block diagram form a representative automated control system for the Figure 1 processing apparatus.
  • said control system 60 includes a conventional velocity type servomechanism to regulate the pipe movement and fiber wrapping operations conducted in said apparatus as dictated by an operator activated interface.
  • Identification numerals employed in the present drawing further include the same numerals previously used in the Figure 1 apparatus description for the purpose of herein denoting the operative association between controlled components of said apparatus and components of the presently illustrated control means .
  • the overall control system 60 herein depicted is of the known master-slave type whereby the tractor feed component 12 operates as the master control component with all cylindrical wrapping components 18, 28 and 38 being slaved thereto.
