Claim:
1. An assembly comprising: an airfoil member having an airfoil portion and a root portion, the airfoil portion having a leading edge, a trailing edge, a first side extending from the leading edge to the trailing edge, a second side extending from the leading edge to the trailing edge and a base near the root portion; and at least one platform defining a channel for receiving the root portion, the at least one platform formed from a composite material and comprising an endwall extending in generally circumferentially opposite directions from either side of the airfoil portion, the endwall having an outboard surface comprising a contoured region, the contoured region including at least one convex region and at least one concave region at a same circumferential side of the airfoil, the at least one convex region extending uniformly in an axial direction from the leading edge to the trailing edge and the at least one concave region extending uniformly in the axial direction from the leading edge to the trailing edge.
