Solvay CYCOM® 5250-4 BMI Prepreg System with IM-7 Carbon Fiber
Categories: Polymer; Thermoset; Bismaleimide (BMI); Carbon Fiber/Thermoset Composite
Material Notes: 60 Volume % IM-7.

CYCOM® 5250-4 is a 350°F to 400°F (177°C to 204°C) curing bismaleimide resin with a service temperature range of -75°F to 400°F (-59°C to 204°C). CYCOM 5250-4 is specifically formulated for use in primary aircraft structures. In addition, a variety of secondary structural components can take advantage of the increased performance from using high-strain carbon fibers and the improved damage-resistance this system provides. CYCOM 5250-4 is available with either carbon fiber or glass fiber reinforcement in unidirectional tape, woven broadgood and roving forms.

Features & Benefits:

  • Short-term service temperature up to 450°F (232°C)
  • Superior hot/wet properties at 220°F to 375°F (104°C to 190°C)
  • Excellent toughness
  • Void-free laminates
  • High temperature resistance
  • Low thermal conductivity
  • Versatile cure
  • Excellent compression strength properties after impact
  • Shop life greater than 28 days at room temperature
  • Fluid/solvent resistant
Suggested Applications: Primary and secondary aircraft structure including:
  • Engine nacelles
  • Fuselage skins and stiffeners
  • Wing and stabilizer spars and skins
  • Other critical load-bearing components
Mechanical properties are reported for standard cure + standard post-cure
