Abstract
The tensile test specimens of ETFE (ethylene - tetrafluoroethylene copolymer) membrane have been done at 7 temperatures. It is obtained corresponding stress - strain tensile curve, tensile strength and breaking elongation. Through experiments, it is given the tensile curves at different temperatures to determine turning points on the two rigid method, which has been a turning point corresponding to the yield stress and strain; and it is given ETFE calculation of elastic modulus by tensile curve calculate the tangent modulus, secant modulus, elastic modulus of the second and third; through numerical calculation, it is measured the energy performance of ETFE membranes. The results of the experiments provide a theoretical basis of ETFE membrane to study the architecture.
