ABSTRACT:
A composite material rotor is disclosed which is made from a plurality of stacked and bonded epoxied filament wound discs, each disc providing a specially wound construction so that the modulus of the rotor body may be varied in proportion to the maximum stress encountered by the rotor during ultracentrifugation. Such a layered disc assembly allows the rotor to be fine-tuned to respond to a variety of stress encountered during ultracentrifugation. Where upper hoop stress is greater, upper disc 28 might be wound using a higher modulus filament fiber than the fiber used by disc 26.
