In this study, composite materials were prepared using unsaturated polyester resins reinforced by Alfa fibres. The fibres were previously modified by chemical treatments, maleic anhydride (MA), styrene (S), acrylic acid (AA) and acetic anhydride (Ac). The Ac and the S treatments allowed an increase in the moisture resistance and the mechanical properties of the fibres. The preliminary S or MA treatment of the fibres allowed a decrease of the water permeability of the composite. A slight increase of the stiffness of the composite was observed due to the presence of the fibres (treated or not), whereas the resistance (breaking strength and strain) was not improved. The mechanical behaviour of the composites appeared similar whatever the treatment of the fibres except with S treatment which seemed to improve the breaking strength.
