| 60 Volume % G30-500. 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.
