Solvay CYCOM® 890 RTM Resin - Woven Carbon Fabric Composite
Categories:	Polymer; Thermoset; Carbon Fiber/Thermoset Composite; Epoxy; Epoxy/Carbon Fiber Composite
Material Notes:	CYCOM® 890 RTM is a one-part liquid epoxy resin system. It has one month out-life at room temperature which reduces the time required for the freeze-thaw-storage processes in a production environment. Its frozen storage shelf-life is 12 months at -18°C (0°F). CYCOM 890 RTM’s viscosity is low enough at 80°C (175°F) to allow injection without excessive heating of either the resin or the transfer pipework. When the resin is heated to cure temperature its viscosity is further reduced, helping to ensure full wet-out of the reinforcing fibers. CYCOM 890 RTM is fully cured after two hours at 180°C (355°F) after which it will have a continuous dry service performance of 170°C (338°F) and a continuous hot/wet service performance of 160°C (320°F) If needed, an optional free-standing postcure for two hours at 200°C (390°F) can be used. After postcure the resin will have a continuous dry service performance of 195°C (383°F) and a continuous hot/wet service performance of 170°C (338°F). CYCOM 890 RTM is compatible with the range of reinforcing fibers used in manufacturing composite components, i.e., carbon, glass, aramid, etc. A fully compatible binder system, CYCOM® 7720 has been developed for use with CYCOM 890 RTM. The binder is available pre-coated onto fabric. A separate datasheet for CYCOM 7720 is available on request. Features & Benefits: One-part system 30 day out-life at room temperature 12 month shelf-life at -18°C (0°F) Injectable at 80°C (175°F) with a 24-hour pot-life 250 cps initial injection viscosity Less than 10 cps minimum viscosity Two hours at 180°C (355°F) cure 170°C (350°F) continuous dry service performance [195°C (383°F) after optional post-cure] 160°C (320°F) continuous hot/wet service performance [170°C (338°F) after optional post-cure] Fully compatible with CYCOM 7720 binder coating and CYCOM® 890-1 low resin content (LRC) filmfor tack enhancing fabrics Low reactivity; No special shipping requirements Applications: Infusion applications requiring low viscosity and extended pot-life Control surfaces Nacelle casing Large surface fairings Hinges/brackets/fittings Mechanical property data for epoxy with 57% fiber volume T650 6K-5HS woven carbon fabric.
