Abstract

Abstract: The application of a porous silica (PS) transition layer in an inorganic-organic aeronautic laminated glass can effectively solve the material failure caused by the performance difference of the inorganic-organic materials. The effect of porous silica transition layer thickness on the mechanical and optical properties of laminated glass was investigated. The microstructure of the porous silica transition layer was analyzed by scanning electron microscopy. The film thickness was verified using a step profiler. The failure strength of laminated glass with the porous silica transition layer was tested by a universal testing machine. Finite element modeling of laminated glass with the porous silica transition layer was performed by ANSYS software. Tensile stress between the porous silica and the polyurethane was simulated for different porous silica film thicknesses. Experimental and theoretical results indicated that with the increasing the thickness of the transition film, the failure stress of the laminated glass increased. Improvements in the mechanical properties of the laminated glass are saturation at a PS thickness of approximately 3.8 μm.

Porous silica transition layer can improve shear resistance of laminated glass. Shear failure occurs at different interfaces when the film thickness is different.
