ABSTRACT This review delineates a transformative strategy in advanced materials: the integration of Ti 3 C 2 T x MXene with carbon fibers (CFs) to forge a new class of multifunctional structural composites. This integration strategy signifies a paradigm shift from simple structural components to multifunctional material systems. Moving beyond conventional interface enhancement, precise modification techniques such as self‐assembly, electrophoretic deposition, chemical grafting, and blending‐spinning synergistically combine the outstanding mechanical properties of CFs with the diverse electrical, thermal, and optical characteristics of Ti 3 C 2 T x MXene. This synergistic coupling effectively overcomes the long‐standing limitations of CFs, including surface inertness and functional singularity. The review systematically examines the resulting performance improvements across a range of frontier applications, including interface reinforcement, electromagnetic shielding, battery energy storage, smart sensing, and thermal management. However, achieving industrial applications still depends on overcoming key challenges related to Ti 3 C 2 T x MXene stability, scalable processing, and multifunctional optimization. This review not only summarizes current research progress but also outlines a roadmap for future studies, emphasizing sustainable processing, interfacial nanoengineering, and the rational design of next‐generation structure‐function‐integrated composites.
