The air permeability and the porosity of polymer materials based on 3d-printed hybrid non-woven needle-punched fabrics

HIGHLIGHTS

  • What: The authors (a) obtained fibrous polymer materials with a porosity gradient in thickness (b) determined the dependence of the material`s porosity coefficient on the speed and temperature of the modification and_(c) developed a model for calculating the porosity coefficient of the materials with specified technological parameters. The aim of the work was to study the effect of the surface density of non-woven fabrics on the formation of a porous structure and the air permeability of the modified hybrid materials which are manufactured using FFF-3D-printing technology.
