## Abstract

This review delineates a transformative strategy in advanced materials: the integration of Ti3C2Tx 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 Ti3C2Tx 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 Ti3C2Tx 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.

This review comprehensively outlines how Ti3C2Tx MXene transforms carbon fiber from a structural component into a multifunctional platform. We systematically detail cutting‐edge modification strategies and showcase exceptional performance in EMI shielding, energy storage, smart sensing, and beyond. The article critically addresses key challenges and charts a course for the future development of these structurally integrated, next‐generation materials.
