<p>Hybrid seals (117) are provided which include a metallic component (127) and a flexible, non-metallic, heat resistant component (129), e.g., graphite, which are fully integrated in the finished seal and thus not subject to delamination. The hybrid seals (117) can be produced from hybrid heat resistant strips (107) that can be wrapped into a preform (109) and then compression molded to form the hybrid seal (117). The hybrid strips (107) have a core (111) that comprises a flexible, non-metallic, heat resistant material and a metal mesh (113) knitted around the core. Prior to being formed into a preform (109), the core and the metal mesh are crimped together to begin the process of integrating the metallic and non-metallic components of the seal. The compression molding completes the integration.</p> |
