There are PVC, PVF, PVDF, PTFE, ETFE that kinds of architectural membrane. Nowadays coated membranes are made of synthetic fibers or glass fibers have durability and mechenical property better than existing membrane, so it have been globally used as a material of large span spatial structures. ETFE membrane is transparent lightweight film form that synthesized teflon and ethylene, so it has longer life cycle than PTFE membrane.
The tensile strength test of PVDF, PTFE, ETFE membrane are performed in this paper. PVDF, PTFE, ETFE membranes with two different thickness are used in this test. The test method is strip method which written in KS K 0521, KS M 3054. In the result of stress strain relationship curve by the different membrane thickness that interpreted by comparative analysis.
