The bending rigidity of laminated fabric was investigated considering the positions of the neutral axes in bending for components in addition to the tensile and in-plane compressive moduli of components. Theoretically derived equations were proposed to obtain the position of the neutral axis and to predict bending rigidity of laminated fabric. Eight face fabrics, ten adhesive interlinings and eighty laminated fabrics of those combinations were used for experimental samples. Tensile properties, bending rigidities and thicknesses of samples were measured and used to investigate the validity of the theory. The positions of the neutral axes for the face fabrics were obtained and they were not close to the centroid of the fabric. The calculated bending rigidities of laminated fabrics using the obtained position of neutral axes were more agreed with the experimental ones than the results by the method without considering the position of neutral axis. Therefore, it was found that the bending rigidity of laminated fabric can be predicted more precisely considering the position of neutral axis.
