CYCOM® 5250-4

CYCOM^® 5250-4 is a 375°F to 400°F (191°C to 204°C) curing bismaleimide resin with a service temperature range from -75°F to 400°F (-59°C to 204°C). CYCOM^® 5250-4 is specifically formulated for use in primary structure elements and full-scale aircraft and space components. In addition, a variety of Aerospace composite structural components can take advantage of the resin’s 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 fabrics, and slit tape forms. Typical applications include primary and secondary aircraft structures including: wing skins, engine nacelles, fuselage skins, ribs, spars, space capsule heat-shields, and other critical load-bearing components.
