The effective elastic properties of injection-moulded short-fibre-reinforced composites are analysed. For unidirectional orientation the model of Tandon-Weng is used. The orientation averaging procedure is used for arbitrary fibre orientation. Finally, the effective elastic properties are calculated based on the thin-laninate theory. The real fibre orientation distributions in a specially designed experimental component are measured and the effective mechanics parameters are calculated based on the measured datum. This method is validated by comparing calculated values with experimental results.
