The new astronomical instruments require high-performance structures. Technological innovation and new materials are
needed for a structure such as the ALMA radio-telescope in order to guarantee the specifications. The use of Carbon
Fibre is highly important. The choice of CFRP helps to control the stiffness of the structure and the thermal behavior of
the pieces, but a deep qualification of the material and process is fundamental. Technologies like hand lay-up vacuum
bag, compression moulding, and filament winding, identify the ideal solutions for big objects, like Main Reflector
Structure, Receiver Cabin, Quadripod Legs and small subassemblies like adjusters system etc.
