Abstract

A cast light metal piston for internal combustion engines is provided with a ceramic insert in those zones which are highly thermally stressed and/or for heat insulation. To form a high-strength bond between the light metal and the insert, high-strength fibers are embedded in the light metal in the zone adjoining the insert.
