Abstract
A method of manufacture of a shaft including positioning a prefabricated wedge member onto a cylindrical mandrel, winding a fibre material onto the mandrel, the fibre material extending over at least a part of the wedge member, allowing a matrix material impregnated into the fibre material to cure, and machining away at least part of the fibre material in the region of the wedge member to expose fibres thereof.
Claims6
A method of manufacture of a shaft comprising;
- positioning a prefabricated metallic material annular wedge member onto a cylindrical mandrel, winding a fibre material onto the mandrel so that the fibre material extends over at least a part of the wedge member, allowing a matrix material impregnated into the fibre material to cure, machining away at least part of the fibre material to expose fibres thereof, and pushing an end fitting onto and around an end part of the shaft thereby applying a compressive load to the annular wedge member.
