Solvay CYCOM® 950-1 Epoxy Prepreg with 38%-G7781
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	CYCOM® 950-1 modified epoxy resin is a 121°C (250°F) cure system with the performance of a 177°C (350°F) curing epoxy. CYCOM 950-1 prepreg is curable under vacuum-bag-only pressure conditions. CYCOM 950-1 is a controlled flow, net resin content material that offers significant advantages over wet lay-up systems for structural repairs. Advantages include favorable stress-strain characteristics, product quality and consistency, speed of lay-up and vastly improved health and safety characteristics. Features & Benefits: Aerospace qualified Low outgassing. Approved for space flight Controlled flow material Improved toughness compared with first- and second-generation structural epoxies Dry service temperature of 150°C (300°F) when cured at 135°C (275°F) Mechanical properties of a 177°C (350°F) curing material when cured at 135°C (275°F) Mechanical properties to 104°C (220°F) hot/wet Oven/vacuum bag cure capability as well as autoclave positive pressure cure Efficient for structural repair Conventional drying, lay-up, vacuum bagging and localized low-level heating is all that is required for most applications Shop life of 8 weeks at ambient conditions Suitable for laminate and sandwich panel usage Co-curable with various aerospace qualified adhesive materials Suggested Applications: Helicopter fuselage and rotor components Wing structures Field repairs and permanent repairs Space flight applications Information provided by Cytec, subsequently acquired by Solvay.
