<p>A hybrid centrifuge rotor having a rotor core (12) surrounded by a prestressed anisotropic reinforcement ring (14) is disclosed. The rotor core (12) may be made from aluminum and an anisotropic reinforcement ring (14) may be a cylindrical filament wound ring, made from graphite fiber and epoxy resin. The rotor core (12) is manufactured to have a nominally greater diameter than the inner diameter of the reinforcement ring (14). This rotor core (12), during the manufacturing process, is subjected to a cryogenic environment where the diameter is shrunk down so that the rotor body may fit and telescope within the reinforcement ring (14). The rotor body core (12) and reinforcement ring (14) assembly, upon attainment of ambient temperatures, have an interface fit wherein substantial outward force from the rotor body core prestresses the reinforcement ring so that a light weight and strong centrifuge rotor is disclosed.</p> |
