<p>Embodiments of the present invention provide a method of forming a component comprising; providing a sleeve member formed from a metal matrix, composite material; and casting a cast portion of the component whereby at feast a portion of the cast portion Is provided within the sleeve member. Embodiments of the invention have the advantage that a component of increased stiffness may be fabricated compared with a cast component not comprising the sleeve member. The component may be formed to he of greater stiffness and reduced weight compared with a component of comparable strength and stiffness formed from a material such as steel.</p> |
