Abstract

The work examines the requirements for conducting bending tests of aircraft floor sandwich honeycomb panel samples and the most common errors in the interpretation of test methods. An analysis of the requirements of aircraft developers for property indicators during bending tests is conducted, along with data from manufacturers of aircraft floor panels. Due to the lack of standards establishing requirements specifically for the bending tests of floor panels, the work provides justifications for applying methodologies that differ from GOST standards, which set requirements for testing sandwich structures.
