Introduction to HexTool® Composite Tooling Material
Hexcel's HexTool® composite tooling material brings together precision accuracy with unparalleled lightness. This innovative patented solution enables the precision typically associated with metals to be coupled with the exceptional lightweight properties of carbon fiber composites. HexTool® molds offer ease of repair and modification, revolutionizing the tooling industry. The material is a game-changer for creating lightweight, efficient large-scale tools that are cost-effective compared to traditional composite tools and metal molds, including those fabricated using Invar®.
Features and Benefits of HexTool® Composite Material
HexTool® boasts a variety of features and benefits that set it apart from conventional tooling materials. With a density of 1.55, the material offers a significant weight reduction compared to aluminum, Invar®, and other tooling options. Its process versatility allows for layup methods such as prepreg, infusion, and fabrication without the need for autoclave curing. HexTool® provides superior dimensional stability, easy repair capabilities, and design flexibility. Moreover, it ensures good dimension tolerances while maintaining a lower coefficient of thermal expansion (CTE) compared to traditional options.
Applications and Testimonials
Since its introduction, HexTool® has been embraced by leading tooling engineers who have noted its exceptional performance. The material maintains dimensional stability and close tolerances akin to metal tooling while guaranteeing vacuum integrity even in heavily machined areas. Its long tool life, user-friendly nature, and machinability of cured structures have made it the top choice for tooling in the aerospace industry. HexTool® M61 and M81 variants offer specific advantages for curing carbon fiber/epoxy parts at different temperatures, providing energy-efficient, cost-competitive, and dimensionally stable solutions.
Future of Tooling with HexTool®
