Steel and aluminium are still reference materials in many industrial transport assembly lines. However, at present, work is ongoing to find alternatives and develop lighter materials, which will make vehicles less heavy, thus allowing fuel savings. The aim is also to promote the integration of materials into transport systems to make them safer and more sustainable.
It is also necessary to look for alternative propulsion ways to those derived from oil. One of the possibilities is solar energy, and in fact there are already models of airplanes that have flown around the world propelled by the light of the sun.
At the same time, a commitment has been made to implement hybridization processes with electric motors in airplanes, thanks to new fuel systems, such as green hydrogen, which is produced by the electrolysis of water from electricity from renewable sources. This fuel that many have already called the fuel of the future has multiplied its demand by three since 1975, and continues to increase today.
The aeronautical industry also works to promote new and diverse materials such as polymer composites. Until now, many aircrafts have been manufactured with thermosetting materials, but they are being encouraged to change to thermoplastics, which can be better recycled to return to the production line.
Along with this, the naval, railway and automotive industries are also rethinking mobility by betting on integrating new materials. The automotive industry is working to develop lighter materials to make vehicles less heavy.
The railway industry, for its part, is testing the use of hydrogen cells (there are already trains with this fuel circulating in Europe). And the naval industry is also working on this line.
