CYCOM 5216 is a 200° to 250°F (93° to 121°C) curing, modified epoxy resin. Service temperature range is -67° to 180°F (-55° to 82°C). This prepreg is manufactured by the hot melt process and is virtually solvent-free.

All three fiber materials — carbon, aramid and glass — are available in unidirectional, woven and, on special order, roving forms. Typical applications include rotor blade spars and skins.

Carbon fiber is a good candidate for aircraft secondary structure, commercial aircraft, and aerospace products. Aramid currently has application in helicopter structure, rotor blades, and high impact resistant laminates. Glass fiber is used in military and commercial helicopter blades and structures and is exensively used for engine nacelles.
