Three-dimensional braided composites are widely used in aerospace structures because of their high specific stiffness, high specific strength, excellent impact resistance and delamination resistance. With the continuous innovation of braiding technology and the continuous development of curing molding technology, three-dimensional braided composites show unique advantages in integrated molding and large-size automatic braiding. In this paper, three-dimensional braiding machines are classified, the difference between three-dimensional braiding and two-dimensional braiding is discussed, the development status of three-dimensional textile preform braiding technology is introduced, and the application status of three-dimensional braiding composites is summarized. Finally, the application prospect of three-dimensional braided composites is prospected.
