Abstract: The fibre orientation in short fibre reinforced thermoplastics depends on injection moulding technology parameters. The aim of this paper is to propose possibilities for comparing fibre orientation of the real sample and the result from simulation software. Fibre orientation of selected injection moulding part is simulated. In some selected points secondorder tensor of orientation was estimated. Stereological metallography was used for possibility of comparison these results with experimental ones. An experimental result of estimation of degree of fibre orientation is described. The use of stereological metallography allows very simple and effective experimental estimation of short glass fibre orientation, which can be used for experimental verification of numerical simulation model, which can be optimized to obtained coincidence with experiments.
