Tearing Behavior of the Polyurethane-coated Fabrics with Five Different Silicone Contents

摘要

The trapezoidal tearing method was utilized for the polyurethane coated fabrics with five different Silicone contents. The correlation of elastic modulus, shear modulus and tearing strength were studied and the results showed that the tearing strength increased following the decrease of elastic modulus. Finite element results were analyzed for the coated fabrics by using orthotropic model. The calculation results showed good agreement with the experimental results.
