CYCOM® PR 520 RTM is a one-part, 180°C (355°F) curing epoxy resin system offering superior damage tolerance and good strain to failure required for composite primary structure applications. The value of resin infusion is the ability to design complex geometric parts while leveraging a unitized structure which ultimately leads to a reduction in weight, lower part counts and the elimination of many post-manufacturing processes. CYCOM PR 520 RTM is an off-white thick paste at room temperature reducing to a low viscosity when heated for injection. The resin has a low enough viscosity to allow injection at 90 - 100°C (194 - 212°F). Following injection, the resin viscosity decreases with increasing tool temperature to below 50 cP, thus helping to ensure full fiber wetting. CYCOM PR 520 RTM resin is fully cured following a 2-hour dwell at 180°C (355°F) after which it has a continuous hot/wet service temperature of 104°C (220°F). For reinforcement preforming operations, a fully compatible binder system, CYCOM® 7720 RTM, and a low areal weight film, PR 520-1, have been developed for use with CYCOM PR 520 RTM. The binder and low areal weight film are available pre-coated onto fabrics of the customer's choice. A separate datasheet for CYCOM 7720 RTM is available upon request. Suggested Applications: Engine Blades Engine Blade Spacers/Platforms Containment Cases Outer Guide Vanes Hinge/Brackets/Fittings
