Summary: The changes in mechanical properties and the water absorption capacity of poly (vinyl chloride)/alfa fibre composites were studied as a function of alfa fibre content (10, 20 and 30 wt %) and its particle size. The study showed that composites samples exhibited higher tensile modulus compared with the virgin PVC, whereas elongation at break and tensile strength were observed to decline. Moreover, the amount of absorbed water depends on the amount of fibre in the composite. The comparison of the results obtained from the samples with different sizes 160, 200, 250, and 315 µm called F160, F200, F250 and F315 and the virgin PVC indicated that the presence of small particle sizes exhibited a beneficial effect on the water absorption by improving the quality of adhesion between polymer and fiber.
