ABSTRACT As a high‐performance fiber material, carbon fiber (CF) has the characteristics of high axial tensile strength, high modulus, good chemical stability, good thermal stability, and so on, and occupies an important position in the field of advanced composites. Its CF hybrid composites, by combining CF with other fibers (such as natural fiber, high modulus CF, or high‐performance synthetic fiber), achieve complementary performance, lightweight design, and cost optimization, and are widely used in automotive manufacturing, aerospace, ship engineering, sports equipment, fan blades, and other fields. This paper reviews the research progress of CF hybrid composites in recent years, systematically analyzes the structural characteristics of CFs and the development of modification technology, discusses the design and preparation of CF hybrid composites, hybrid effect and mechanism, the influence of hybrid ratio and structural design on its mechanical properties, expounds the research status of CF hybrid composites in mechanical properties and fatigue properties, focuses on the research progress of its impact properties, summarizes its innovative applications in aerospace, engineering, transportation and other fields, and finally puts forward the development direction of future research.
