TY - CONF A1 - Trappe, Volker A1 - Günzel, Stephan A1 - Goebbels, Jürgen T1 - Modelling the damage behaviour of short fibre reinforced composites using a non-destructively evaluated fibre orientation distribution and micro cracking N2 - Short fiber reinforced thermoplastic materials were investigated non-destructively in different damage states by X-ray computer tomography (CT) and small angle X-ray scattering (SAXS) to analyze the damage behavior due to mechanical loading. First the orientation distribution of the short fiber in a polyamide matrix were determined by high resolution CT as basis to separate the micro cracking in the matrix and fiber matrix debonding quantitatively by X-ray refraction topography (using SAXS-technique) and a specific model. Finally based on the model and perpendicular X-ray-refraction-topography scans, the materials damage state could be stated efficiently.
