The cells of rigid polyurethane foams show an elongated shape in foaming direction, so that rigid polyurethane foams exhibit anisotropy in mechanical properties. We attended to relationship between mechanical properties and the cell shape. Six types of rigid polyurethane foams have been studied. We have so far investigated the image processing system which extracts the geometrical information on cell shape using the cross-sectional picture of rigid polyurethane foams. Therefore, we suggested that the cell shape of polyurethane foam can be approximated to be oval, the oval diameters and the area distribution on the cells of an initial state have been evaluated. We discussed about the relationship between cell shape and compressive properties of rigid polyurethane foams.
