   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 golf club head has a volume ranging from 420 cubic centimeters to 470 cubic centimeters.   
     
     
         2 . The golf club head according to  claim 1  wherein the golf club head has an Izz moment of inertia ranging from 4000 g-cm 2  to 6000 g-cm 2 . 
     
     
         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 first carbon based material has continuous fibers and the second carbon based material has chopped fibers. 
     
     
         6 . The golf club head according to  claim 1  wherein the sole portion has a toe edge wall and a heel edge wall. 
     
     
         7 . 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 . 
     
     
         8 . The golf club head according to  claim 1  wherein the golf club head has an Ixx moment of inertia ranging from 2000 g-cm 2  to 3500 g-cm 2 . 
     
     
         9 . A golf club head comprising:
 a face component with a stiffening member having a wishbone structure, the stiffening member located within 1 inch and has a height ranging from 2 inches to 3 inches;   a central body component comprising
 a crown portion composed of a continuous carbon fiber reinforced epoxy material, wherein the crown portion has a thickness ranging from 0.025 inch to 0.040 inch, 
 a sole portion composed of a chopped carbon fiber reinforced vinyl ester sheet molding compound material, the sole portion having a thickness ranging from 0.040 inch to 0.240 inch, 
 wherein the crown portion is attached to the sole portion, 
 wherein the central body component has a front opening and a rear opening with a hollow interior; 
   an aft-component composed of a metal material disposed in the rear opening of the central body 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 golf club head has a volume ranging from 420 cubic centimeters to 470 cubic centimeters.   
     
     
         10 . The golf club head according to  claim 9  wherein the golf club head has an Izz moment of inertia ranging from 4000 g-cm 2  to 6000 g-cm 2 . 
     
     
         11 . The golf club head according to  claim 9  wherein the face component is composed of a titanium alloy material. 
     
     
         12 . The golf club head according to  claim 9  wherein the aft-component is composed of a metal material. 
     
     
         13 . The golf club head according to  claim 9  wherein the golf club head has an Iyy moment of inertia ranging from 2500 g-cm 2  to 4000 g-cm 2 . 
     
     
         14 . The golf club head according to  claim 9  wherein the golf club head has an Ixx moment of inertia ranging from 2000 g-cm 2  to 3500 g-cm 2 .
