Abstract
An ultracentrifuge rotor comprising a body portion formed as a bowl with a central open chamber defined by a thin, cylindrical wall extending from a supporting base and a plurality of nested rings of filament windings surrounding the cylindrical wall for strengthening and stiffening same. The nested rings result in a uniform filament density throughout the ring assembly.
Claims19
An ultracentrifuge rotor comprising:
- a body portion;
- and
- a plurality of nested rings of filament windings surrounding said body portion for strengthening and stiffening same.
A method for fabricating an ultracentrifuge rotor comprising the steps of:
- providing a body portion;
- and
- surrounding said body portion with a plurality of thin, nested rings of wound fibers.
A reinforced ultracentrifuge rotor comprising:
- a titanium bowl element;
- and
- a plurality of turns of a filamentary material having a lower density, higher modulus of elasticity and higher tensile strength than titanium, secured around the periphery of said rotor element, whereby the maximum rate of rotation of said rotor is substantially increased.
