A stator vane frame assembly including an outer structure ring (34), an inner structure ring (36), a set of discrete vanes (22) each connecting the outer structure ring (34) and the inner structure ring (36) forming an inner and outer platforms with neighboring vanes (22) defining a set of flow paths, a set of sealing members (30, 32, 58, 70) contoured to a set of gaps (60) between the set of vanes (22) disposed to sealing the gap (60). A method for applying a sealing member (30, 32, 58, 70) to the gaps (60) between a platform formed resulting from the coupling between vanes (22) including affixing a set of stator vanes (22) on an inner frame and an outer frame, and sealing a set of sealing members (30, 32, 58, 70) on the backside surface of a stator vane frame. The discrete nature of individual vane blade sealed by the sealing members (30, 32, 58, 70) renders the stator vane frame assembly to add a damping effect which increases the fatigue life of the vane (22), and permits the use of lower strength, lighter, and less expensive material.
