Hexcel will be promoting the very fast curing HexPly M77 epoxy prepreg resin system at the ISPO winter sports exhibition, taking place in Munich, 6-9 February (stand no. 347, Hall A4).
This product cures under 5 minutes and is designed to provide a very efficient composite manufacturing process for ski and snowboards. Curing in only 2 minutes at 300F/150C, HexPly M77 also has a shelf life of 6 weeks at 23C. The material has a Tg of 120C/250F and good adhesive properties (for example when bonding to honeycombs or aluminium), intended to make HexPly M77 suitable for large volume production.
Based on HexPly M77 resin system, Hexcel has launched a range of prepregs with glass or carbon reinforcements in multiaxial form as well as woven fabrics and UD tapes.
