Statische und dynamische Eigenschaften von Hochleistungsverbundwerkstoffen
We investigated the influence of the fiber, matrix and interface properties on the static and dynamic properties and behavior on mechanical impact of advanced composite materials. Three different matrix systems have been combined with a glass fiber and two carbon fibers to nine different composite materials and studied their behavior with tensile, pressure and shear stress. The effects of composite components on the static properties were compared with theoretical predictions.
The behavior on mechanical impact has been described with the energy to initiate the delamination. With increasing strain, the neat resin composite to absorb more energy, caused by delamination. To determine the dynamic characteristics of load increase and fatigue tests were carried out using the hysteresis measurement method. A particularly suitable criterion to detection of material damage with in cross laminates proved by the dynamic modulus of elasticity. The modulus drops in the increasing load test at glass fiber laminates by the formation of transverse cracks and rises with carbon fiber laminates.Lesen Sie die deutsche Zusammenfassung auf Kunststoffe.de
