HexTOOL® M81

Composite tooling material for components cured at 250°F to 300°F (120°C to 150°C)
HexTOOL® M81 Tooling Compound is randomly layered strips of uni-directional prepreg consolidated into continuous rolled goods. It can be utilized for 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 is ideally suited for 250°F to 300°F (120°C to 150°C) curing carbon fiber tools and can also tolerate several cure cycles at 355°F (180°C). The resulting tools are lighter and more energy efficient than tools made from steel or aluminum.  They are also cost-competitive and provide tighter mold tolerances than standard composite tooling.

HexTOOL® means that accurate and expensive master molds are no longer necessary. Hexcel has evaluated cost-effective master mold solutions.
