The creep phenomenon in fiber-reinforced composites is particularly important when macro synthetic fibers are used, due to their low modulus of elasticity, exhibit pronounced viscoelastic behavior even at room temperature, which can lead to changes in the cracking control over time. Pullout tests are commonly used to predict fiber–matrix interactions and in this work were conducted for short- and long-term on three types of polymeric macro fibers. Different levels of long-term loads (20, 30, 40 and 50 percent of the maximum short-term pullout load) and fiber orientation angles (15 degrees celsius, 30 degrees celsius, and 45 degrees celsius) with respect to the direction of the load were considered to investigate the influence of these parameters on the interaction between macro synthetic fibers and matrix. Macro fibers with crimped surfaces and higher modulus of elasticity achieved higher bond stresses and lower creep deformations. In short-term tests, optical microscopy images were obtained on the pulled-out fibers to correlate the surface degradation of the fibers with the stress versus strain curves. In quasi-static pullout (short-term), small reductions in pullout strength were observed for all fibers and angles, in addition to an intensive degradation of their surfaces owing to the significant snubbing effect of this type of fiber. In contrast, for the long-term tests, a creep reduction was observed with increasing fiber inclination angle caused by the creep reduction of the fiber due to non-axial loading and additional force components produced by the deviation of the axial force. The Burgers viscoelastic model was applied and showed good agreement with the experimental creep curves, therefore consisting of a promising alternative for modeling the long-term behavior of individual fibers. Microtomography and scanning electron microscopy images showed that a large portion of the strain in tension, under sustained load, can be attributed to the creep of the fiber itself, thus making it challenging to estimate the creep of this type of composite, given the considerable variability of fiber configurations.
