PTIR™ Fiber Reinforced Thermoplastic
Prepregs for Composites (patent pending)

PTIR™ Prepreg

Kubota Research Associates, Inc. has developed a new GREEN process for manufacturing fiber reinforced thermoplastic prepregs. PTIR™ prepreg was developed with funding from NSF SBIR project #0512869. The prepregs are applicable to Out of Autoclave (OOA) composite forming methods including cold press forming to maximize productivity.

PTIR™ Prepreg, thermoformable sheets and MemBond™ films contain a PTIR™ IR emitter dispersed in a thermoplastic matrix. The matrix resin is impregnated onto a reinforcement fabric such as carbon fiber and polyarylate LCP fiber.

PTIR™ Prepregs are tailor-made to meet industry and customer needs.

A range of PTIR™ thermoplastic resins address industry applications such as aerospace, automotive and other high performance composite requirements. Kubota Research offers PTIR™ Prepregs made using the following thermoplastic resin matrix materials:

  • Ionomer
  • Polyurethane
  • Polypropylene
  • PMMA
  • Polyamide
  • PPS
  • PEEK
  • Polyimide (TPI)

PTIR™ Prepreg materials are made using carbon fiber, and organic fiber in woven fabric and unidirectional forms. Kubota Research offers PTIR™ Prepregs made using the following high tenacity fiber materials:

Toray Carbon Fiber T700 12K UD Plain Weave Braid
Vectran® HT LCP Fiber UD Plain Weave Braid
