Present state of development of a mechanical model for point-bonded webs is reported. It is assumed that the web, consisting of straight fibers of equal (finite) length, uniform areal density and orientation distribution is subjected to general homogeneous deformation. The two-dimensional model developed can account for a range of specific bond patterns and basis weights. It also accounts for the actual load-deformation properties of the constituent (homogeneous) fibers. The prediction of fabric strength is simulated by breakage of fibers bridging the bonds or failure of the bond itself. For the latter mode, two basic mechanisms are postulated: fiber pullout and destruction of the bond-site itself. Theoretical results have been obtained to elucidate the role of bond pattern, bond area fraction, fiber length, shape of the bond-site and bond strength on the fabric strength. Qualitative comparisons with experimental data are presented.
