Abstract
The invention provides a high-strength hybrid component comprising a relatively soft first part -made of a composite material consisting of an organic matrix reinforced with fibres, a relatively hard second part made of metal, metal alloy or ceramic, and a transition layer made of a composite material consisting of a matrix of a material which is weldable to the hard part and fibres which are extensions of the fibres of the soft part. The transition layer matrix and the hard part may be formed by deposition of molten material on to the fibre preform of the soft part, using flame, electric arc or plasma, and the resin matrix of the soft part is impregnated into the preform and polymerized afterwards. Alternatively, the hard part may be machined to shape and welded to the transition layer before completing the soft part.
