This work deals with the characterization and modeling of fibers in short fiber reinforced polymers by means of X-ray computed tomography (XCT). Taking into account the actual fiber network within a component it is possible to achieve exact results for stress analyses. Within the XCT device a tensile testing stage was mounted which was used to test the specimens up to different loads. Between the increases of load, XCT scans were performed to determine the actual damage of the fibers. From the fiber data, determined by XCT analyses, representative volume elements (RVE) were created. The main damage mechanisms that were identified are fiber breakage, fiber pullout and lateral detachment. The actual degree of damage was integrated into the RVE via fiber data from XCT analyses. The calculation of stresses of single fibers show high values for long fibers in tensile direction. The matrix around the fibers shows very inhomogeneous stress distribution with higher values at the end of the fibres.
