an aft-component;
wherein the face component is attached to a front opening of the central body and the aft component is attached to a rear opening of the central body;
wherein the first carbon based material has continuous fibers and the second carbon based material has chopped fibers:
wherein the golf club head has an Izz moment of inertia ranging from 4000 g-cm 2 to 6000 g-cm 2 .

2. The golf club head according to claim 1 wherein the face component is composed of a metal material.

3. The golf club head according to claim 1 wherein the face component is composed of a titanium alloy material.

4. The golf club head according to claim 1 wherein the aft-component is composed of a metal material.

5. The golf club head according to claim 1 wherein the sole portion has a toe edge wall and a heel edge wall.

6. The golf club head according to claim 1 wherein the golf club head has an Iyy moment of inertia ranging from 2500 g-cm 2 to 4000 g-cm 2 .

7. A golf club head comprising:
a face component with a stiffening member;
