Study on tensile properties of coated fabrics and laminates

267-272The influence of structural parameters of coated fabrics and laminates on the breaking force, elongation, tensile energy during their stretching in various directions and types of failure has been studied. It is observed that the tensile properties of coated fabrics and laminates depend not only on the structural characteristics of the ir base layer but also on polymer film and degree of its penetration into the base layer. The analysis of stress-strain curves and fabrics fracture shows three types of fabrics distortion, namely instantaneous, continuous for sometime and breaking of fabrics separate layers at different durations. The tensile direction for coated fabrics and laminates has considerable influence on tensile characteristics
