| Abstract Scope |
Silicon carbide (SiC) based ceramic matrix composites (CMCs) offer significant advantages over conventional superalloys, including higher temperature capability, reduced cooling requirements, and lower material density. A key challenge to the broader implementation of CMC components is the development of reliable joining and integration approaches capable of supporting large, complex geometries and integration with metallic systems. Because each joining application involves unique material combinations, geometries, thermomechanical environments, and service-life requirements, tailored joining solutions are required. Thermomechanical simulations were utilized to evaluate stress distributions and deformation behavior for both CMC-to-CMC and CMC-to-metal joints and compared with experimental testing. A particular focus was on stress evolution within joint sub-elements and interfacial joining layers to identify peak stress regions and critical failure drivers. The outcomes provide insight into joint design optimization and contribute to increasing the technology readiness level of advanced CMC joining and integration technologies for next-generation aerospace applications. |
