Mechanisms are presented which occur in unidirectional fiber reinforced plastics due to fiber fracture and subsequent crack evolution. The 3‐point‐bending test was chosen as test method and the analyses are predominantly carried out by microscopy. It is shown that the matrix system, the fiber‐matrix interface adhesion strength and the fiber volume fraction are of great importance for improving fatigue strength. The results can be transferred directly to high stressed bending structures such as leaf springs.
