Abstract: With the increasingly urgent demand for heavy launch vehicle in the future, under the condition of a certain total load, the weight of the carrying cargo must be reduced, which puts forward higher requirements for the existing materials and structures. Increasing the payload ratio of materials without sacrificing strength and functionality is a major challenge. At present, the most common and efficient method is through the design and fabrication of a variety of new sandwich structures, meeting the requirements of lightweight, high strength and functional. The paper summarizes the research progress of sandwich structures in China and abroad in recent years, introduces in detail the structural foundation and characteristics, mechanical properties and diverse functions of several sandwich structures, and puts forward some suggestions for the research and development of sandwich structures in our country.

Key words: sandwich structure, light, creative design, versatility, composite
