Experiment Study on Uniaxial Properties of PVC Membrane Material

Abstract:

Uniaxial tensile tests of PVC membrane are carried out at seven kinds of temperature. The change law of tensile strength, strain at break and the Young’s modulus at different temperature are obtained from the tests. The results indicate with the increase of the test temperature, the tensile strength decreases while the tensile strain at break increase, but the load-deformation curve trends are similar. By using molecular break theory, the fitting formulas are proposed to predict the effect of temperature on tensile strength. In addition, the cycle loading tests were carried out in three different phases. This paper studies the residual strain and the elasticity change of the PVC membrane during the test. The results indicate PVC membrane is typical elasto-plasticity material. With the increase of cycle loading the residual strain increases.
