In 2015, Airrus started developing some prototypes based on a new type of pre-preg with unusual characteristics. The tests showed surprising results in terms of blank lightness , torsional and compression resistance.  The efficiency of this new type of material is based on its  polyacrylonitrile resin that optimize the carbon fiber features. Airrus named it "Magma Polymer Technology" and it was applied on the Ultra-X and Bora Series.
