Abstract The properties of the tube components are the significant factors affecting the reliability of aircraft. The rapid development of domestic large aircraft and military aircraft has put forward higher requirements for lightweight, high efficiency and high reliability of aircraft. The structure of integral multi bend and compact complex structure are the future development direction of the tube system. Composite materials have been widely used in aircraft because of their excellent comprehensive properties. The demands of high performance and lightweight integrated manufacturing of tubes used on aircraft can be satisfied by replacing metal tubes with fiber reinforced polymer (FRP) composite tubes. At present, FRP composite tubes have been gradually applied in a small amount of aircrafts and which have broad market prospects in the future. The manufacturing process of FRP composite tubes mainly involve the selection of materials, the selection of manufacturing process methods and equipment, and the optimization of process parameters, and each link plays a crucial role in the forming quality of the FRP composite tubes. In this paper, the global market and application of FRP tubes are introduced, and the comparison of performance between resin and fiber reinforced materials, as well as the manufacturing process characteristics of the commonly used FRP tubes are analyzed. On this basis, the development and the research status of filament winding technology in the manufacturing of FRP tubes in recent years are reviewed and the future development trend is prospected.
