An artificial limb component having one portion with an open channel cross-section and method for making the component in which woven sheets of carbon fibre reinforced plastics material in prepreg form are laid up on an inflatable expandable moulded mandrel, which is then placed in a lower mould half, a corresponding upper mould half being placed on the lower half to complete the mould. Air pressure is applied via pipe to the interior of the mandrel which is expanded within the mould halves to compress the prepreg sheets to the required shape.
