RESEARCH REGARDING UNIAXIAL TENSILE STRENGTH OF NYLON WOVEN FABRICS, COATED AND UNCOATED WITH SILICONE

Properties of woven fabrics used to make airbag cushions are influenced by a lot of factors: the nature of raw materials, woven fabric geometry and density, technological parameters of the weaving operation and finishing. The main purpose of this research paper is to find the values of three mechanical parameters - tensile strain, tensile stress and specific modulus - according to the type of samples and test direction on the testing stand. To obtain woven fabric samples were used polyamide 6-6 polyfilament yams (nylon), silicone coated and uncoated fabric. Testing procedure and samples preparation were done following the standard EN ISO 13934-1:1999. Test results and graphs show that, we have a good unifomiity of the geometry for the analyzed fabrics.
