Abstract: Aluminum foam has been widely used due to its excellent mechanical, electrical and thermodynamic properties. In order to expand the application, researchers have put a lot of effort into the preparation of high-performance composite aluminum foam. Lots of studies have shown that the method of preparing composite foam by adding different kinds of reinforcements can improve the strength of the composite foam, but it will cause various problems. For example, hard ceramic particles (SiC particles, Al2O3 particles and so on) can improve the compressive strength, but it will cause the problem of brittleness; the two-dimensional reinforcement (such as fiber and whisker) can reduce the brittleness, but there are still many difficulties in uniform distribution and the treatment of reinforcement. Besides that the method is cumbersome and the interface reaction is difficult to control. Therefore, whether aluminum foams or composite foams are rarely used alone. In most cases, aluminum foam is combined with other high-strength components, such as aluminum foam sandwich panels and aluminum foam filled thin-walled metal tubes. The aluminum foam filled thin-walled metal tube composite structure is a special structure that aluminum foam core fills into a thin-walled metal tube through various ways and achieve an effective connection. At present, the met-hod of achieving filling can be divided into external filling method and in-situ preparation method. The aluminum foam filled thin-walled tube structure not only has excellent energy absorption and damping properties, but also has certain toughness and high independent load-carrying capacity. As a new type of composite structure, aluminum foam filled thin-walled metal tube has great potential in shock absorption, noise absorption and reduction. In particular, the aluminum foam filled thin-walled metal tube composite structure has great potential practical value and broad application prospects in the automobile manufacturing industry, which has attracted the attention of researchers. Compared with the traditional shock absorbing structure, the aluminum foam filled thin-walled metal tube has three obvious advantages in the automobile manufacturing industry: (i) greatly reducing the weight of the vehicle body, reducing the fuel consumption and exhaust emissions of the automobile without reducing the strength of the vehicle body; (ii) the structure relies on its own plastic deformation can absorb most of the collision energy and disperse the impact on the body of the vehicle to avoid causing excessive local deformation, so that it can fully guarantee the safety of passengers; (iii) the rebound deformation of the structure is low, which can effectively avoid the secondary injury of the human in the accident. At present, the most common composite structure application is used as bumpers, sub-frames, front longitudinal beams and other energy-absorbing components of automobiles, which reduces the production cost and improves the safety factor of automobiles. This paper introduces the main preparation methods and performance characteristics of the aluminum foam filled metal thin-walled tube compo-site structure, describes the research status of the composite structure at home and abroad and forecasts its future research direction.
