The tensile strength test and result comparison of new transparent architecture membrane material STFE
STFE(structural, transparent, fluorinated, envelope) membrane material is a new type of transparent architecture membrane material. Compared with general architecture membrane materials, which have the disadvantage of cannot balance strength and transparency, STFE has both high transparency and certain tensile strength. In this study, tensile strength tests were conducted on this new type of membrane material, and data obtained from different test methods, such as clamping test, winding test, and dumbbell-shaped test, were compared, and the mechanism for the differences was analyzed. The results showed that the winding-type test with smooth surface contact yielded the highest and most accurate strength data, clamping tests due to the tendency of the specimen to slip out of the clamping end, dumbbell tests due to the stress concentration effect, and winding tests with rough surface contact due to material damage caused by pressure, all reduce the measured tensile strength values. The measured tensile strength of STFE membrane material was 4241N/5 cm in the warp direction and 4335N/5 cm in the weft direction. This indicates that STFE membrane material has sufficient strength to be used in tensile membrane structures.
