摘要：

Poly(ethylene tetra fluoroethylene) or ETFE can be extruded into foils, and has been used for cladding and roof applications since the 1980s. ETFE is usually formed into internally pressurized cushions by inflating two or more layers of foil. Creep of ETFE increases with increased axial stress, and axial tensile stress often must be increased in the foils as a means of raising transverse load-carrying capacity. This paper presents results of tests on ETFE foils under tensile loading conditions. Test results of the research described herein consist of creep strain responses over time, and stress-strain responses. Modelling of the time-dependent material response is also included.
