Abstract
The invention herein relates to a flywheel capable of high speed rotational operation in excess of 15,000 rpm, the flywheel comprising a composite rotor having a polymeric matrix in which are embedded fibers helically wound at an initial angle with respect to the axis of rotation of the rotor of from about 50° to about 80° and increasing in a stepwise or continuous manner to about 90°.
Claims10
A flywheel, comprising:
- a composite annular rotor having a central axis of rotation perpendicular to the composite annular rotor, wherein:
- the composite annular rotor comprises a matrix material in which fibers are embedded at a concentration of about 50% to 80% by volume, the fibers being helically wound at an initial angle of about 50° to about 80° relative to the axis of rotation, the winding angle increasing to about 90° in a continuous manner where the fibers comprise:
- a single chemical composition within a first chemical class of fiber;
- or
- variable chemical compositions within a first chemical class of fiber;
- or
- a first chemical class of fiber, which may comprise a single chemical composition or variable chemical compositions, wound to a predetermined rotor dimension whereupon a second chemical class of fiber which may comprise a single chemical composition or variable chemical compositions, is introduced either gradually or all at once.
