Thin-walled stiffened composite structures have gradually been used in aerospace

naval vessels

extreme engineering and other high-end equipment due to their light weight

high strength

corrosion resistance

fatigue resistance and other advantages. This article reviews recent progress in terms of structural design of thin-walled stiffened structures

additive manufacturing processes for composite materials

and applications of thin-walled stiffened composite structures in high-end equipment. For the structural design of thin-walled stiffened structures

the methods including parametrization method

shape optimization method

topology optimization method

and other advanced methods are outlined. The development of composite additive manufacturing

such as filament winding

automatic fiber placement and 3D printing technology

and fiber path planning methods are discussed. Then

typical applications of thin-walled stiffened composite structures in the field of high-end equipment are sorted out. Moreover

the development trend and challenges of the design and manufacturing of thin-walled reinforced composite structures are summarized. Finally

we summarize the development trends and challenges in structure-process integrated design of thin-walled stiffened composite structures.
