Process for manufacturing motor car steering wheels with an external shell made of composite materials

摘要

A process for manufacturing motor car steering wheels with an external shell made of composite materials comprises preparation of piles (7) of sheets of composite materials, hot moulding thereof for obtaining respective half-shells (6) with a shape corresponding to that of respective halves of the steering wheel being manufactured, mechanical flattening of the front surfaces (16) of the two half-shells, application of the two half-shells to opposite parts of a steering wheel body (18) formed by a metallic core (4) covered by resin (5) and mutual fixing of the two half-shells (6) along said front surfaces (16). After flattening the front surfaces (16) of the two half-shells (6) are mechanically worked to form respective complementary teeth (14, 15) which can be male-female coupled when the two half-shells (6) are applied around the steering wheel body (18).
