Heraeus Noblelight, has collaborated with Compositadour, Coriolis and Hexcel, to apply their breakthrough composites heating technology – humm3® – to the manufacture of a full-scale aerospace demonstrator panel from dry fibre composite material.
The geometrically complex dry fibre preform was created at Compositadour’s research centre using the humm3® heating technology. The humm3® was mounted to a Coriolis robot-based Automated Fibre Placement machine, which was configured to lay up 8 quarter-inch tows of Hexcel’s HiTape® dry carbon fibre reinforcements. The preform was then infused with Hexcel’s HexFlow® RTM6 resin using standard techniques at Compositadour.
The humm3® has proved itself to be an excellent heating technology for fast and controllable dry fibre lay-up. The combination of high average power, fast control and small physical volume enables a wide range of complex geometries to be fabricated. The humm3® is also safe to use (no laser safety enclosure is required) and is easily scaled to different heated widths, from less than 1 inch up to 12 inches and beyond.
