1. A combustor liner segment seal member, comprising: a center section having a base surface, a gas path surface exposed to a gas path of a combustor, a forward side surface, and an aft side surface;a forward flange extending outwardly from the forward side surface, the forward flange having a width
1. A combustor liner segment seal member, comprising: a center section having a base surface, a gas path surface exposed to a gas path of a combustor, a forward side surface, and an aft side surface;a forward flange extending outwardly from the forward side surface, the forward flange having a width, a height, a shell side surface, and a liner side surface; andan aft flange extending outwardly from the aft side surface, the aft flange having a width, a height, a shell side surface, and a liner side surface;wherein a forward combustor liner segment is disposed on the liner side surface of the forward flange and an aft combustor liner segment is disposed on the liner side surface of the aft flange. 2. The seal member of claim 1, wherein the center section has a height that is greater than the height of the forward flange and the height of the aft flange. 3. The seal member of claim 2, wherein a thermal barrier coating is attached to at least one surface of the seal member. 4. The seal member of claim 1, wherein the seal member is configured to form a circumferentially extending seal. 5. The seal member of claim 1, wherein the base surface of the seal member is planar. 6. The seal member of claim 1, further comprising one or more cooling air slots disposed in the liner side surface of at least one of the forward flange and the aft flange. 7. The seal member of claim 6, wherein the cooling air slots extend across substantially all of the width of the flange in which the slots are disposed. 8. The seal member of claim 7, wherein the seal member is configured to form a piece of a circumferentially extending seal. 9. A combustor for a gas turbine engine, comprising: a support shell of the combustor, the support shell having an interior surface;a forward liner segment attached to the interior surface of the support shell, the forward liner segment having an edge surface extending between a face surface and a back surface, and a seal shoulder portion;an aft liner segment attached to the interior surface of the support shell, the aft liner segment having an edge surface extending between a face surface and a back surface, and a seal shoulder portion;wherein the forward liner segment and the aft liner segment are separated from one another by a gap; anda seal member disposed within the gap, the seal member having a center section, a forward flange, and an aft flange;wherein the seal shoulder portion of the forward flange is disposed on the forward flange of the seal member and the seal shoulder portion of the aft flange is disposed on the aft flange of the seal member. 10. The combustor of claim 9, wherein the center section of the seal member has a height that is greater than a height of the forward flange and a height of the aft flange. 11. The combustor of claim 9, wherein a thermal barrier coating is attached to at least a surface of the seal member. 12. The combustor of claim 9, wherein the seal member is configured to form a circumferentially extending seal. 13. The combustor of claim 9, wherein the seal member includes one or more cooling air slots disposed in a liner side surface of at least one of the forward flange and the aft flange, which one or more cooling air slots provide a cooling air passage between the respective flange and the seal shoulder. 14. The combustor of claim 13, wherein one or more cooling air slots extend across substantially all of the width of the flange in which one or more slots are disposed. 15. The combustor of claim 9, wherein the seal member center section has side surfaces that have a profile that mates with a profile of the edge surfaces of the forward and aft liner segments.
