Park Aerospace Nelcote® E-765 Epoxy Prepreg, 7781 E-Glass Reinforced
Categories: Polymer; Thermoset; Epoxy

Material Notes: Nelcote® E-765 is a tough 250°F cure prepreg system designed to replace 350°F cure systems in aircraft structural applications. FAA-approved Design Allowable Databases are available upon request.

Key Features and Benefits:

  • Designed to replace first generation 350°F (176°C) cure systems.
  • Wide cure temperature process window of 250°F to 350°F
  • Exhibits very low void content, i.e., <2% after vacuum cure.
  • Superior fiber property translation.
  • 180°F Wet service temperature after ~250°F cure
  • Good tack and drape characteristics for 3 weeks at room temperature

Applications/Qualifications:

  • Primary Aircraft Structures
    • Fuselage
    • Wing
    • Control Surfaces
  • Secondary Aircraft Structures
    • Aircraft Frames
    • Doors
    • Shelves
    • Bulkheads
