1. A vane arc segment comprising:
an airfoil fairing formed of a ceramic matrix composite and having first and second fairing platforms and an airfoil section extending therebetween, the airfoil section having a pressure side, a suction side, and an internal cavity,
the first fairing platform defining suction and pressure side circumferential mate faces, forward and aft faces, a gaspath side, a non-gaspath side, and a flange projecting from the non-gaspath side,
the flange extending along the suction side circumferential mate face, and
a rib having a rib section in the internal cavity spanning the pressure side and the suction side and a rib extension section extending from the rib section in the internal cavity and along the non-gaspath side of the first fairing platform, the rib extension intersecting the flange to form a gusset for reinforcing the flange, the rib extension terminating at a fillet between the pressure side of the airfoil section and the first fairing platform, and the first fairing platform including a seal flange projecting from the non-gaspath side and overhanging the pressure side circumferential mate face.
