Abstract
A high-strength hybrid component including a relatively soft first part made of a composite material including an organic matrix reinforced with fibers, a relatively hard second part made of metal, metal alloy, or ceramic, and a transition layer made of a composite material including a matrix of a material that is weldable to the hard part and fibers that are extensions of the fibers of the soft part. The transition layer matrix and the hard part may be formed by deposition of molten material on to the fiber preform of the soft part using flame, electric arc, or plasma. 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.
