JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Asia 2012 - HexMC is a new product form of composite material which is derived from established aerospace industry high strength carbon fiber/epoxy tape.
The first Boeing 787 was delivered on September 26th 2011, an aircraft on which hundreds of HexMC parts from Hexcel have been certified. HexMC is a new product form of composite material which is derived from established aerospace industry high strength carbon fiber/epoxy tape. HexMC offers low density, with good strength and stiffness properties, enabling complex shapes that would previously have had to be machined or forged from metal to be manufactured in composites in cost-effective series production. HexMC parts provide weight savings that are comparable to those achieved with aerospace carbon/epoxy prepregs.
Hundreds of HexMC parts have been certified for the 787 Dreamliner including Window Frames, Brackets, Fittings, Gussets, Clips/Cleats, Intercostals and Pans. The HexMC window frame has a significant impact on two key characteristics of the Dreamliner. The new low density, high strength composite frame results in almost a 50 percent weight saving over a traditional aluminum frame. In addition, the frame offers superior damage tolerance.
