|Summary||Composite materials which are highly used in high technology industries such as aeronautic and space are nowadays introduced in building industry.
Because of their good physicochemical characteristics, composite cables can be used as substitute for steel in prestressed concrete. However, their long term mechanical behaviour is still not fully understood. Therefore, a rheological model describing the creep behaviour of cords of Kevlar type 49 is presented in this study. The obtained simulations are in good agreement with the experimental results.
