Abstract: Flexure testing is one of the earliest means of evaluating stiffness and strength. This test is suggested to use in determination of the facing properties of the resistant materials (Kuenzi, 1951). This study was carried out to perform bending test of sandwich constructions suitable for ASTM D7249/D7249M standards and to determine facing material properties of sandwich constructions through evaluating the experimental data. Performing and conducting of the test: this study was carried out with collaboration of the Istanbul University and Turkish Airlines Technic under privacy in order to determine the facing properties of the sandwich constructions and it includes experimental and numerical methods. The study was carried out based on accepted standards.

Keywords: ISSA; sandwich constructions; aviation; bending tests; A-basis values; long beam flexure.
