Advanced Composites Group Ltd. (ACG, Heanor, U.K.), part of the Composites Division of Umeco plc, has launched HTM60, its latest high-temperature molding epoxy resin matrix system, designed for motorsport applications. Fully post-cured, the resin system is capable of generating an onset Tg of 230°C/445°F and retains a Tg of 155°C/310°F under wet conditions. It will also adhere directly to Nomex honeycomb. The new resin system is specifically targeted at both structural and bodywork type applications at all levels in motorsport and is designed as an alternative to cyanate ester and bismaleimide systems. HTM60 is available for use with a range of unidirectional, biaxial and woven carbon fiber materials.
