Einfluß der Laminatkomponenten von CFK-Werkstoffen auf das statische und das dynamische Verhalten

Influence of Different Laminate Components on the Static and Dynamic Properties of CERP The static and the dynamic properties of a conventional and a modified, toughened matrix system reinforced with two high strength carbon fibres of a different strain to failure was investigated. Three different laminates were chosen, an unidirectional laminate 0₈], a cross ply laminate 0₂, 90₂, 0₂, 90₂]_s, and a nearly quasi-isotropic laminate 0₂, ±45, 90 ]_s. It is shown, that the damage development under static as well as dynamic loading is delayed when using a toughened matrix system. This delay in damage development results in improved mechanical properties. However, when using a toughened matrix system together with fibres of a high strain to failure, the improvement of the static properties does not lead in the same extent to an improvement of the dynamic properties.
