Brano has been experimenting with unusual frame materials and techniques for some time.
You may have seen his BME branded bikes before, particularly those in bamboo or carbon/titanium truss.

X-9 Nighthawk is an experimental frame made out of sandwich panels with aramid honeycomb as a core, covered with carbon fiber skins.
