Research Status of 3D Braiding Technology

Three-dimensional braiding composite material has the advantages of high strength, high modulus, high temperature resistance, non-layered structure and easy design. Traditional high-performance metal materials will be replaced by 3D braiding composite material, so it has been highly valued and applied in many fields such as aerospace, weaponry and equipment. At present, there are many researches on 3D braiding technology, such as 3D rotary braiding machine and Cartesian 3D braiding machine in terms of braiding equipment. The research on the structure of preforms and the performance of composite materials are also more in-depth. The development of 3D braiding technology from the aspects of 3D fabric, braiding technology, equipment are summarized in this article. The development of 3D braiding technology requires high-speed automation and commercialization, this will be a challenge for 3D braiding technology in the future.
