In one example, a golf club head includes a body portion and a face portion attached to the body portion that comprises a center portion having a first thickness, a perimeter portion having a second thickness greater than the first thickness, spoke portions extending radially from the center portion to the perimeter portion, and recessed portions. Each recessed portion is located between two spoke portions, and each recessed portion extends from the center portion to the perimeter portion. The thickness of each spoke portion increases from the first thickness to the second thickness in a direction from the center portion to the perimeter portion, and each recessed portion has the first thickness from the center portion to the perimeter portion. Other examples and embodiments may be described and claimed. ## Claims ### Claim 1 A golf club head comprising: a body portion having a front portion with a front opening to an interior cavity; a face portion attached to the front portion to close the front opening, the face portion comprising: a center portion having a first thickness; a perimeter portion having a width extending from a perimeter edge of the face portion toward the center portion and having a second thickness greater than the first thickness; a plurality of spoke portions extending radially from the center portion to the perimeter portion; and a plurality of recessed portions, each recessed portion located between two spoke portions, and each recessed portion extending from the center portion to the perimeter portion and being recessed relative to the perimeter portion, wherein the second thickness is a maximum thickness of the face portion, wherein a thickness of each spoke portion increases from the first thickness to the second thickness in a direction from the center portion to the perimeter portion, wherein each recessed portion has the first thickness from the center portion to the perimeter portion, wherein the perimeter portion and the plurality of spoke portions define a continuous back surface portion of the face portion, and wherein a maximum thickness of each spoke portion is the second thickness. ### Claim 2 (depends on 1) A golf club head as defined in claim 1, wherein the center portion and the plurality of recessed portions are filled with a polymer material. ### Claim 3 (depends on 1) A golf club head as defined in claim 1, wherein the interior cavity is at least partially filled with a polymer material. ### Claim 4 (depends on 1) A golf club head as defined in claim 1, wherein a size of the center portion is proportional to a loft angle of the face portion. ### Claim 5 (depends on 1) A golf club head as defined in claim 1, wherein at least two spoke portions of the plurality of spoke portions have different widths and different lengths. ### Claim 6 (depends on 1) A golf club head as defined in claim 1, wherein a width of each spoke portion increases in a direction from the center portion to the perimeter portion. ### Claim 7 (depends on 1) A golf club head as defined in claim 1, wherein a width of each recessed portion increases in a direction from the center portion to the perimeter portion. ### Claim 8 A set of golf club heads comprising: a first golf club head having a first loft angle, and at least a second golf club head having a second loft angle greater than the first loft angle, each golf club head comprising: a body portion being hollow to define an interior cavity; a face portion attached to the body portion, the face portion comprising: a center portion having a first thickness; a perimeter portion having a width extending from a perimeter edge of the face portion toward the center portion and having a second thickness greater than the first thickness; a plurality of spoke portions extending radially from the center portion to the perimeter portion; and a plurality of recessed portions, each recessed portion located between two spoke portions and spaced apart from the perimeter edge by the perimeter portion, and each recessed portion extending from the center portion to the perimeter portion, wherein a thickness of each spoke portion increases from the first thickness to the second thickness in a direction from the center portion to the perimeter portion, and wherein each recessed portion has the first thickness from the center portion to the perimeter portion, and wherein an area of the center portion of the second golf club head is greater than an area of the center portion of the first golf club head, wherein the perimeter portion and the plurality of spoke portions define a continuous back surface portion of the face portion, wherein a maximum thickness of each spoke portion is the second thickness, and wherein a maximum thickness of the perimeter portion is the second thickness. ### Claim 9 (depends on 8) A set of golf club heads as defined in claim 8, wherein the center portion and the plurality of recessed portions of each of golf club heads are filled with a polymer material. ### Claim 10 (depends on 8) A set of golf club heads as defined in claim 8, wherein the interior cavity of each of the first golf club head and the second golf club head is at least partially filled with a polymer material. ### Claim 11 (depends on 8) A set of golf club heads as defined in claim 8, wherein an increase in the area of the center portion of the second golf club head compared to the area of the center portion of the first golf club head is proportional to an increase in the second loft angle compared to the first loft angle. ### Claim 12 (depends on 8) A set of golf club heads as defined in claim 8, wherein the center portion is elliptical, and wherein an end portion of each spoke defines a perimeter of the center portion. ### Claim 13 (depends on 8) A set of golf club heads as defined in claim 8, wherein a width of each spoke portion increases in a direction from the center portion to the perimeter portion. ### Claim 14 (depends on 8) A set of golf club heads as defined in claim 8, wherein a width of each recessed portion increases in a direction from the center portion to the perimeter portion. ### Claim 15 A golf club comprising: a shaft having a first end coupled to a grip and a second end; and a golf club head coupled to the second end of the shaft, the golf club head comprising: a body portion having a front portion with a front opening to an interior cavity; a face portion attached to the front portion to close the front opening, the face portion comprising: a center portion having a first thickness; a perimeter portion having a width extending from a perimeter edge of the face portion toward the center portion and having a second thickness greater than the first thickness; a plurality of spoke portions extending radially from the center portion to the perimeter portion; and a plurality of recessed portions, each recessed portion located between two spoke portions, and each recessed portion extending from the center portion to the perimeter portion and being recessed relative to the perimeter portion, wherein the second thickness is a maximum thickness of the face portion, wherein a thickness of each spoke portion increases from the first thickness to the second thickness in a direction from the center portion to the perimeter portion, wherein each recessed portion has the first thickness from the center portion to the perimeter portion, wherein the perimeter portion and the plurality of spoke portions define a continuous back surface portion of the face portion, and wherein a maximum thickness of each spoke portion is the second thickness. ### Claim 16 (depends on 15) A golf club as defined in claim 15, wherein the center portion and the plurality of recessed portions are filled with a polymer material. ### Claim 17 (depends on 15) A golf club as defined in claim 15, wherein the interior cavity is at least partially filled with a polymer material. ### Claim 18 (depends on 15) A golf club as defined in claim 15, wherein the center portion is elliptical, and wherein an end portion of each spoke defines a perimeter of the center portion. ### Claim 19 (depends on 15) A golf club as defined in claim 15, wherein at least two spoke portions of the plurality of spoke portions have different widths and different lengths. ### Claim 20 (depends on 15) A golf club as defined in claim 15, wherein a width of each spoke portion and the width of each recessed portion increases in a direction from the center portion to the perimeter portion.
