Solvay CYCOM® 977-2 Epoxy - Carbon Fiber Laminate
Categories: Polymer; Thermoset; Carbon Fiber/Thermoset Composite; Epoxy; Epoxy/Carbon Fiber Composite

Material Notes: CYCOM® 977-2 is a 350°F (177°C) curing toughened epoxy resin with a 260 – 280°F (126 – 138°C) dry and 220°F (104°C) wet service capability. CYCOM 977-2 is formulated for autoclave or press molding. Unidirectional tape and woven fabric impregnated with CYCOM 977-2 resin will retain tack for at least 10 days at 72°F (22°C) and has a long mechanical out life suitable for fabrication of large structures. The recommended lay-up procedure for this material is L-15. The recommended cure is C-50.
