Turbine wheel for hydrokinetic torque converter, and method of making the same

A hydrokinetic torque converter rotatable about a rotational axis, the torque converter comprising:

• an impeller wheel coaxial with the rotational axis, the impeller wheel including an impeller shell and a plurality of impeller blades outwardly extending from the impeller shell;
• and
• a turbine wheel disposed axially opposite to the impeller wheel, the turbine wheel coaxially aligned with and hydro-dynamically drivable by the impeller wheel, the turbine wheel comprising
• an annular turbine shell member coaxial with the rotational axis and made of metallic material, the turbine shell member having an axially inner peripheral surface and an axially outer peripheral surface axially opposite to the axially inner peripheral surface;
• and
• a plurality of turbine blades extending from the axially inner peripheral surface of the turbine shell member;
• each of the turbine blades made of polymeric material as a single-piece component and directly non-moveably secured to the turbine shell member.
