HexTool® M61 Quasi-isotropic High Temperature Prepreg Tooling Compound Product Data Sheet Description HexTool® 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® has proved to be dimensionally stable with the ability to hold vacuum integrity before and after machining, and after more than 500 part cure cycles. Fabricated from Hexcel’s BMI resin HexPly® M61, HexTool® tools are ideally suited for 180°C (356°F) cure carbon fibre tools. This makes them lighter weight, more energy efficient than tools made of steel or Invar®, and more cost-effective with tighter mould tolerance than standard composites. Benefits ¥¥Ability to machine tool surface without distortion permitting the manufacture of tools with complex shapes and tight tolerances ¥¥Lighter weight compared to metal tooling allowing easier handling and reduced infrastructure investment ¥¥Faster heat-up and cool-down rates relative to metal tools facilitating reduced production costs ¥¥Reparability and potential for modification of tool dimensions following engineering changes ¥¥Formulated to withstand several hundred autoclave cycles at 180°C (356°F) ¥¥Coefficient of thermal expansion to match carbon/epoxy ¥¥Vacuum integrity following machining ¥¥Rapid material deposition as HexTool® is much thicker than standard composite tooling prepregs Copyright © 2015 – Hexcel Corporation – All Rights Reserved. ® Invar is a trademark of IMPHY S.A.

HexTool® M61 Quasi-isotropic High Temperature Prepreg Tooling Compound Product Data Sheet Typical Autoclave Cure Cycle Specific cure cycles [temperature, pressure (amount and application of)] depend on autoclave type and dimensions, the extent and type of tooling used and the size and complexity of the lay-up. Please contact your local Hexcel Technical Support for consultation prior to cycle definition. The following cycles are typical for HexTool® M61. Low Temp Cure Cycle and Post Cure Cure Cycle 240 min 190 must be fully thermocoupled prior to the start of the cure cycle (ref. HexTool User...

HexTool® M61 Quasi-isotropic High Temperature Prepreg Tooling Compound Product Data Sheet Storage and Handling Store the product in its original (or equivalent) sealed packaging at -18°C (0°F). Prevent condensation on the productby warming to room temperature before opening vapor barrier bag (reseal for subsequent storage). The usual precautions when handling uncured synthetic resins and fine fibrous materials should be observed, see Material Safety Data Sheet. The use of clean disposable impervious gloves provides protection for the operator and avoids contamination of material and components....
