Process for the manufacture of undulated metallic elements for the reinforcement of composite materials

摘要

A process for the manufacture of filiform reinforcement elements of steel in the form of ribbons is improved by projecting a jet of liquid steel onto a cylinder rotating in a cooling medium and imparting a relative reciprocating movement parallel to the axis of rotation of the cylinder between the jet of liquid steel and the cylinder in order to undulate the ribbon in the direction parallel to the axis of rotation of the cylinder.
