Solvay CYCOM® 985 Epoxy + Carbon Uni-Tape Laminate
Categories: Polymer; Thermoset; Carbon Fiber/Thermoset Composite; Epoxy; Epoxy/Carbon Fiber Composite

Material Notes: CYCOM® 985 is a 350°F (177°C) curing epoxy resin system. CYCOM 985 is designed for use where a balance of performance and processing characteristics is required. It has excellent structural performance and good impact resistance. CYCOM 985 is co-curable with structural adhesives and will produce outstanding thin-skinned sandwich structures. CYCOM 985 allows thick section construction without exotherm problems. Optimum properties are achieved by curing under autoclave pressure from 45 to 100 psi (as appropriate to panel configuration) at 350°F (177°C) for two hours. CYCOM 985 prepregs have good tack and drape and an out-time of two weeks at room temperature.

Features & Benefits:

  • Modified epoxy system
  • Excellent hot/wet strength retention
  • 350°F (177°C) cure
  • Good impact resistance
  • 300°F (149°C) service temperature
  • Controlled flow
  • Ease of processing
  • Good tack and drape
  • 14 day shop life
  • Shelf life of 6 months at 0°F (-18°C)
Applications: Primary and secondary aircraft structures
