Amber Composites Ltd. (Nottingham, U.K.) has developed Multipreg C640, a new low-temperature-cure cyanate ester resin system. Developed to cure at temperatures as low as 70°C/158°F, C640 complements Multipreg C740, both of which are designed for high-temperature applications. Typical applications using Amber’s cyanate ester technology include brake ducts and exhaust components for high-performance cars and components for unmanned aircraft, such as the Schiebel Camcopter S-100. Characteristics include a variable cure system that can be processed at low to medium temperatures; freestanding postcure at temperatures as high as 300°C/572°F; Tg onset at 335°C/635°F, following 300°C/572°F postcure; and four-day out life.
