The development situation of reticulated ceramic-metal composites is presented in this paper. The currently multiple fabrication techniques and their advantages and disadvantages are discussed respectively. In the fabrication of composites, the pressureless and pressure liquid metal infiltrations for reticulated ceramic-metal composites are introduced and compared with each other. A description of the wetting types of the ceramic-metal phase is also introduced. By adding elements, wrapping and heating treatment, these methods are put forwards to improve the wetting of ceramic-metal. The interface structure types of ceramic-metal composites are described. The development direction of the reticulated ceramic-metal composites is described. The several key points of fabrication of reticulated ceramics are put forward to meet the requirements for shock-resistant composites.
