摘要：
A rotor sleeve (46) for a rotor (29) of an electric machine (28). The sleeve comprises a plurality of layers (66a, 66b) of carbon fibre reinforced polymer,
each layer (66a, 66b) comprising fibres (68) oriented substantially 90° to a rotational axis (X) and at least one layer (72a) of fibres (74) having a lower modulus of elasticity provided between layers (66a, 66b) of carbon fibre reinforced polymer. The lower modulus of elasticity fibres (74) are oriented between 50° and 75° relative to the rotational axis (X).
