Solvay CYCOM® 381 Epoxy Prepreg with S2 Uni-glass 284FAW Epoxy
Categories: Polymer; Thermoset; Epoxy

Material Notes: CYCOM® 381 epoxy prepreg is an epoxy prepreg that offers a 250°F (121°C) curing system with high 180°F (82°C)/wet mechanical properties yet has the excellent fatigue and durability necessary for primary structure applications.

Features & Benefits:

  • Excellent 180°F (82°C)/wet properties
  • Service temperature to 220°F (104°C)
  • Three- to four-fold increases in fatigue life compared to perhaps all conventional 250°F (121°C) curing epoxy prepregs. This increase is the result of a 10 – 15% higher strain endurance limit.
  • Inherent toughness provides good durability and compression after impact performance
  • Low moisture absorption
  • Excellent for vacuum pressure/oven processing
Applications:
  • Primary and secondary structural aircraft parts requiring 180°F (82°C)/wet retention of properties and/or excellent fatigue behavior
  • Components that require good durability and/or low processing temperatures
  • Helicopter rotor blades
  • Rotating or cycled components
  • Co-cured aluminum assemblies/parts
  • Doublers
  • Propellers
  • Composite repair
