Solvay CYCOM® 5216 Epoxy - Woven Aramid Fiber Prepreg
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	CYCOM® 5216 is a 200 – 250°F (93 – 121°C) curing, modified epoxy resin. Service temperature range is -67 to 180°F (-55 to 82°C). This prepreg is manufactured by hot melt processing and is virtually solvent-free. Typical applications include rotorblade spars and skins. Aramid reinforced CYCOM 5216 has application in helicopter structure, rotorblades and high impact resistant laminates. Available in unidirectional, woven and, on special order, roving forms; also with carbon and glass fiber. Features & Benefits: Excellent fatigue resistance High flow with long shop life Autoclave and press cure Maximum continuous service temperature up to 180°F (82°C) Low pressure moldable Good tack and drape characteristics Excellent translation of fiber strength Tape laying machine capable Applications: Aircraft secondary structure Rotorcraft structure and blade applications Mechanical property data for Standard Cure, Aramid Fiber, Woven (Kevlar style 285) tested in warp direction.
