The invention provides an aviation high-temperature titanium alloy honeycomb wallboard and a manufacturing method thereof, and belongs to the field of aviation aircraft manufacturing, the high-temperature titanium alloy honeycomb wallboard is formed by connecting an upper skin, a lower skin and a honeycomb core between the upper skin and the lower skin through vacuum brazing, and the upper skin, the lower skin and the honeycomb core are all made of high-temperature titanium alloy. The manufacturing method comprises the following steps: preparing the upper skin, the lower skin and the honeycomb core; after brazing filler metal is pasted to the to-be-welded positions of the upper skin and the lower skin, the upper skin, the lower skin and the honeycomb core are assembled; and under the set vacuum degree, the temperature is increased to the brazing temperature according to the set heating path, and honeycomb wallboard brazing is completed. The prepared high-temperature titanium alloy honeycomb wallboard is good in forming and high in high-temperature mechanical property, and can meet the high-temperature-resistant performance requirement of a high-Mach-number aircraft.
