On the Damage Evolution and the Mechanical Degradation of Glass-Fibre Non-Crimp Fabric Reinforced Epoxy Under Tensile Loading: Experimental and Finite Element Modelling

The stiffness and damage evolution in a quasi-static tensile loaded non-crimp fabric reinforced epoxy was measured. To determine the effective stiffness of the damaged material numerically a finite element analysis was performed. The finite element analysis bases solely on the measured ±45° and 90°-...

Description
Summary:The stiffness and damage evolution in a quasi-static tensile loaded non-crimp fabric reinforced epoxy was measured. To determine the effective stiffness of the damaged material numerically a finite element analysis was performed. The finite element analysis bases solely on the measured ±45° and 90°- crack densities and on ply properties calculated by the Rule of Mixtures. The measured and calculated effective tensile stiffness were compared and a fair agreement could be found.
