In a piston for an internal combustion engine with a ceramic section, for example a combustion chamber recess, reinforcing the piston, the connection between piston body and ceramic section is achieved by an annular metal cushion fitted between the two components, which cushion is filled with a propellant, which in the gaseous state increases its volume as the temperature increases, thereby producing the desired contact pressure between the components. <IMAGE>
