Abstract
The visco-elastic behaviors of coated fabrics are important for the design of membrane structure. In this paper, Ferrari 1002 is taken as the research object. The tests of creep and stress relaxation are carried out under five temperatures (23, 40, 50, 60, and 70 ) and three initial stresses (4, 15, and 26 kN/m), respectively. Results show that temperature and initial stress has great effects on the visco-elasticity of coated fabrics. With temperature and initial stress increasing, the visco-elastic behaviors are more obvious. The creep strain can be ignored compared with the corresponding elastic strain. After 24h, the remaining stress is less than 80% the initial stress. This paper can be references for the design of membrane structure.
