Material Notes:
HexTOOL™ M81 Tooling Compound is randomly layered strips of uni-directional prepreg which is consolidated into rolled goods. It can be utilized as multi-ply quasi-isotropic hand lay-up, and subsequently CNC milled to close tolerance. HexTOOL™ M81 has proved to be dimensionally stable with the ability to hold vacuum integrity before and after machining. Fabricated from Hexcel's epoxy resin HexPly® M81, HexTOOL™ M81 tools are ideally suited for 120°C to 150°C cure carbon fiber tools but can also accept several cure cycles to at 180°C. This makes them also lighter weight, more energy efficient than tools made of steel or aluminum but also more cost-effective with tighter mould tolerance than standard composites tools.Information provided by Hexcel
