Many applications have been developed by taking advantage of the combined properties of rubber and textiles. For example, the shear behavior of rubber-coated fabrics is governed by the interaction of its two components, which is dependent on the yarn mobility. In this paper, the effect of coating penetration and thickness on the shear behavior is studied, along with the development of a combined lubrication theory and flow through a porous media model for coating penetration. For the shear deformation of the fabrics, nine types of woven PET fabrics are made and dip-coated multiple times in neoprene latex, with and without a coagulant agent. The results show that with the increase of coating thickness and penetration, the shear behavior becomes more similar to cord/textile embedded in rubber. The results from the modeling section suggest that a model can be developed to link the process and the material parameters to the ensuing coated fabric structure and its mechanical response.

Key Words: shear behavior • rubber-coated fabrics • yarn mobility • coating penetration • coating thickness • lubrication theory • Darcy’s law
