Abstract

The superior mechanical and thermal properties of continuous graphite fiber reinforced aluminum matrix composite (C_f/Al) make it attractive from a design standpoint for space-based system for which the lightweight, high stiffness structure is one of the key technologies. This paper describes the development process of a C_f/Al lens barrel used in space infrared optical system including fabrication technology, structure design and simulation analysis. The advantages and disadvantages of C_f/Al lens barrel compared with invar and CFRP lens barrel, whose structure parameters are identical to that of C_f/Al lens barrel, are discussed. Some performance figures and data are given. The results indicate that the performance of C_f/Al lens barrel is significantly better than the invar, and close to CFRP. However lower outgassing than CFRP under the vacuum condition make C_f/Al become a better choice for space infrared applications.
