Abstract
A structural component that experiences a changing magnetic field during use is described. The structural component can be a stator bore tube, a stator tooth or stator support, for example. A stator bore tube is made of a multi-layered composite material with layers of unidirectional carbon fibre reinforced polymer (CFRP). The eddy current direction is along the axis of the stator bore tube. The carbon fibres in the CFRP layers are orientated along the circumferential direction of the stator bore tube.
Claims16
A structural component, comprising:
- at least one layer of unidirectional carbon fibre reinforced polymer, wherein carbon fibres of the unidirectional carbon fibre reinforced polymer are orientated along a direction that is substantially perpendicular to an eddy current direction,
- wherein the structural component is configured to experience a changing magnetic field during use, the changing magnetic field acting to induce eddy currents in the structural component along the eddy current direction.
