Abstract
A method of manufacturing motor car steering wheels with an external shell made of composite materials, which comprises preparing a pile of sheets of composite materials, hot molding thereof for obtaining respective half-shells with a shape corresponding to that of respective halves of the steering wheel being manufactured, mechanical flattening of the front surfaces of the two half-shells, applying the two half-shells to opposite parts of a steering wheel body formed by a metallic core covered by resin, and mutual fixing of the two half-shells along said front surfaces. After flattening, the front surfaces of the two half-shells are mechanically worked to form respective complementary teeth which can be male-female coupled when the two half-shells are applied around the steering wheel body.
