The composite slurry was poured into a metallic mould, after the stirring was completed.
The Schütte head, for example, had to be blown into a lost wax mould, and required 40 days' cooling before it was completed.
The front monocoque/cockpit moulds are complete and we've already received a fibre glass "splash" (test piece) from URT, before they get on with completing the final carbon fibre components.
This was repeated for the target models after conventional nasoalveolar moulding had been completed.
After the synthesis process is completed, the alumina mould can be dissolved and the CNTs released from its matrix.
According to Chad Fauks, manager of global digital sourcing at Starkey, a Minnesota-based manufacturer of hearing aids, the process of sculpting and moulding the final product can now be completed within a day.
Preliminary investigation into thermal de-binding of cyanoacrylate from alumina has been completed with promising results, proving that cyanoacrylate is a useful constituent for reaction moulding.
Once the mould for the cockpit outer shell (the carbon fibre monocoque) was complete, we made a second mock-up from this mould, to refine the position of the seat, windscreen, instrument panels, and so on.
Later the mould was grown in fermenters.
The complete mould is heated in an oven, and all the wax melts out through the rods and the ingot.
