A flywheel 70 used for kinetic energy storage and a method of manufacture of the flywheel using composite materials are provided. The flywheel 70 comprises a rotor support 74 for coupling an annular flywheel rotor 26 to a shaft 76 for rotation with the shaft. The support 74 comprises a body having a longitudinal axis 81 about which it rotates in the finished flywheel assembly. The body comprises a stack of sheets (see 101 to 105 in Figures 4 & 5) of a composite material including fibres, the stack includes at least two unidirectional sheets, each having substantially all of their fibres extending in the same direction, and the fibres of one of the unidirectional sheets are orientated at a different angle to the longitudinal axis of the body to the fibres in another unidirectional sheet. |
