A magnetically loaded composite rotor is formed by providing a mandrel (1) having a longitudinal axis (2). A release agent (3) is coated on the mandrel and a fibre material (4) of woven or non-woven material having fibres extending in the direction of the axis (2) is applied over the release agent. A thermoplastic resin impregnated tow (24) including magnetic particles (28) is wound over the fibre material (4), the fibre material substantially preventing the magnetic particles penetrating through to the mandrel. |
