Abstract

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.
