In the field of air transport, rail transport and the like, aluminium has replaced steel, and in the future light-weight composite materials will replace aluminium. A new technique based on filament winding enables parallelepiped elements to be enclosed between internal and external walls of the box. The flexion and torsion resistance is substantially equal to that of aluminium but with half the weight. Aircraft structure, TGV railway car body, helicopter rotor blade are examples of the products which can be made with such method. |
