Abstract

Short fibre reinforced polymer structural components, which are often applied in the automotive sector have, due to innovative lightweight designs in general, complex geometries with many notches. Therefore, the effect of notches interacting with the local fibre orientation on the life time prediction needs to be investigated. By notching injection moulded flat specimen extracted from plates, an directed and known fibre orientation around the notch exists. Fatigue tests have been performed on notched specimen with different notch radii and fibre orientations in order to examine the influence of notch sharpness and the local fibre orientation on high cycle fatigue. The results show an up to 30% higher notch support number in longitudinal specimen, compared to transversal oriented specimen. Moreover it can be shown, that notches decrease the endurable fatigue strength, different, depending on fibre orientation. However the endurable fatigue strength show an increase at specimen with very sharp notches compared to the remeaing, investigated notches.
