Amber Composites (Langley Mill, Nottingham, U.K.) has added three products to its HX Series tooling prepreg line. The expanded offering provides a greater range of out-life and cure-schedule options to tool manufacturers, enabling larger tools of higher quality for complex composite structures. New additions include HX32 and HX40, which enable larger tools with extended out-life, and HX44 with similar properties but specially formulated for glass tooling. One customer said that after using Amber’s established HX42 tooling system, the new HX32 prepreg was trialed in two weights: 200g/m2 and 650g/m2. The customer reported that handling of the new material has been easy, with good tack and drapability. Also, curing at 70°C/158°F for 12 hours was convenient and yielded good surface finish and tool quality.
