Study on Flexural Strength of Double Skin Metal Faced Polyurethane Sandwich Panel for Building
Meng Fanbo, Qu Shuying, Li Cuiling and Sun Mingshe

Abstract: Equivalent elastic modulus of double skin metal faced polyurethane sandwich panel with the same thickness of surface layer was derived. Some numerical simulations were performed to find out the relevance of PUSP (Polyurethane sandwich panel) between its’ bending properties and the thickness of material supported on both ends and four edges by ANSYS. The outcome was compared with an experimental investigation on a construction system based on completed in situ sandwich panels subjected to transverse loading. Results show that constraint conditions have significant effect on the flexural bearing capacity of the sandwich panel for walls and roof panels. Thickness of face layers and interlayer affect the bearing capacity by changing the shear force distribution coefficient. It is reasonable to select calculation results as the flexural bearing capacity calculated by the design formula in the standard (GB 23932-2009 - T) when the deflection meet the requirements.
