Solvay CYCOM® 5250-4 BMI Prepreg System with G40-800 Carbon Fiber
Categories:	Polymer; Thermoset; Bismaleimide (BMI); Carbon Fiber/Thermoset Composite
Material Notes:	60 Volume % G40-800. 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 Information provided by Cytec, subsequently acquired by Solvay.
