The effect of opening-pore size in the silica transition layer surface on mechanical properties of aeronautic laminated glass was investigated. The microstructure of the pore of porous silica transition layer was analyzed by scanning electron microscopy. The interfacial shear strength between inorganic glass and polyurethane of porous silica transition layer in laminated glass was tested by universal testing machine. The finite element models of laminated glass with porous silica transition layer were established by ANSYS software based on the pore shape obtained by experiments. The tensile stress between porous silica and polyurethane with different pore area was simulated. The results indicate that with the increasing of pore area, the shear strength between inorganic glass and polyurethane in laminated glass first increases rapidly, and then decreases slowly. When the pore area is 52.61 μm2, the laminated glass has the best mechanical properties.
