Resumo
This paper analyzes both the carbon fiber-based development for uranium centrifuges and the research project
that supports its development effort over time. The carbon fiber-based engineering properties make it a valuable
supply for high technologic products. Nevertheless, its fabrication occurs only in few developed countries and
there is no production in Brazil. In addition, the carbon fiber-based products have dual applications: they can be
used by the civilian and military industry. Therefore, there are international restrictions related to its use and
applications that justify the internal development. Moreover, the Brazilian Navy centrifuges for uranium
enrichment were developed using carbon-fiber which contains polyacrylonitrile (PAN) as an imported raw
material. The PAN properties of low weight, high tensile strength increase the isotopic separation efficiency.
The Brazilian financial scenario surrounded by the international uncertain economy shows that combined
creative project solutions are more effective. Therefore, the Navy's Technological Center in Sao Paulo
(CTMSP), the University of Campinas (UNICAMP), the University of São Paulo (USP), the RADICIFIBRAS
Company, and the Brazilian FINEP agency, which is responsible for the project financial support, established a
partnership aiming the development of a domestic PAN-based carbon fiber industry. The innovative project
solutions adopted and the results of this partnership are presented here.
