In order to reduce fuel consumption due to environmental aspects, weight of automotive compo-nents has to be reduced. Fibre reinforced polymers have high potential to contribute to this aim as they feature a high ratio of stiffness to weight. The direct processing route for long fibre reinforced polymers is a potential process for the net shape series production of automotive parts. To retain safety and comfort, the material properties of polymers processed in such a way have to be investi-gated thoroughly implementing a deeper understanding of elastic response and damage mechanisms. This work deals with glass fibre reinforced polypropylene manufactured by a direct LFT processing route (D-LFT). After introducing basic properties, different composite material models to describe elastic behaviour are presented. These were applied to the material using computer tomography (CT) data describing the microstructure of the composites. Then studies to determine damage evolution are presented. In this regard, the decrease of stiffness with increasing strain was analyzed using tensile tests featuring loading-unloading cycles. The same decrease could also be seen in ultrasonic phase spectroscopy (UPS) tests, carried out on new and damaged specimens. This method is used in this study for the first time to describe the elastic properties of long fibre reinforced thermoplastics.
