In view of the problem of traditional continuous carbon fiber toughened ultra-high temperature ceramic matrix composites (Cf /UHTCs), such as long preparation period and high cost, an internal grouting process of carbon fiber based on ultrasonic regulation technology was proposed to realize the uniform distribution of ceramic powder in carbon fiber braided body, and the mechanical properties of the prepared composites were analyzed. The research results show that the mechanical properties of the composites can be effectively improved by using ultrasonic regulation technology to assist the internal grouting of carbon fiber, and it has a remarkable effect in the preparation of ultra-high temperature ceramic matrix composites toughened by continuous carbon fiber, which can improve the material preparation efficiency and improve the material properties at the same time, and plays a very important role in promoting the innovation of composite preparation technology.
