Abstract
A composite cylinder for an actuator. The cylinder includes a radially inner fibre-reinforced polymer layer defining a hollow bore, a radially outer fibre-reinforced polymer layer, a primary conductive coil, and a first and second secondary conductive coil wound between the radially inner fibre-reinforced polymer layer and the radially outer fibre-reinforced polymer layer. The first secondary conductive coil extends axially along at least a first region of the cylinder and the second secondary conductive coil extends axially along at least a second region of the cylinder, and wherein the primary conductive coil extends axially along at least a central region of the cylinder between the first region and the second region.
