In order to meet the requirements for high-precision and high-efficiency production of high-performance honeycomb sandwich structures

the research progress of precision forming technology of thin-walled titanium alloy honeycomb core and corrugated sheet are presented in this paper. Firstly

the components of thin-walled  oneycomb sandwich structures and their excellent strength

stiffness and heat-resistant performance characteristics are introduced. Secondly

three main manufacturing methods for honeycomb cores are summarized

i.e.

stretching

additive manufacturing and stamping/rolling. The advantages

disadvantages and applicable conditions of the three methods are analyzed. Further

the thin-walled corrugated sheets manufactured by forming method are analyzed in detail: how such thin-walled structures can be fabricated based on stamping or rolling process are expounded

the uniformity improvement of foil deformation

springback reduction of thin-walled structures and forming accuracy enhancement obtained by controlling the material orientation

process parameters and external energy field are summarized. Lastly

the challenges and development aspects of titanium alloy honeycomb sandwich structures and corrugated sheets in precision forming are prospected.
