Abstract
This manuscript studies the tension-tension fatigue behavior of a carbon fabric reinforced PPS and the influence of the specimen geometry on the obtained results. First, the fatigue experiments are preformed according to the ASTM D3479/D3479M standard using the rectangular shaped specimen, but virtually all specimens fail in the tabbed section. This, however, means that fatigue lifetime may be underestimated. Therefore, a new dumbbell-like shape was assessed. Based on the occurring stress concentrations in the tabbed section, the dog bone-like shape was first optimised numerically using FEM, and then, the optimised specimen was tested in tension-tension fatigue. It can be concluded that this dumbbell shape yields better results in terms of acceptable failure and that the used shape has a significant influence on the fatigue lifetime.
