Advanced Composites Group Ltd. (ACG, Heanor, U.K.), a member of the Composites Division of Umeco plc, has launched HTM143, a high-temperature molding and low-moisture pick-up cyanate ester resin matrix system suitable for space and satellite applications. With a 0.55 percent weight gain on neat resin, HTM143 reportedly exhibits one of the lowest moisture pick-up rates of all comparable systems currently on the market. With a long out-life of 21 days and a Tg capability of 250°C/482°F, achieved after a suitable post-cure, HTM143 can be used to manufacture space structures exhibiting high dimensional stability. This material, which is non-ITAR listed, has already been selected for use on several satellite programs and is available for use with a range of unidirectional, biaxial and woven carbon fiber materials.
