In this study,we attempted to characterise the effects of date-palm fibre(DPF)and a date-palm fibre/sheep wool hybrid in polyester to enhance high-performance and low-cost composite materials that can be used in insulation building systems,automotive parts,and home *** DPF was treated using 5%NaOH solution;and the sheep wool was cleaned with 50℃hot water and *** composite specimens were prepared with different fibre contents(0%,10%,20%,30%(w))using a compression moulding *** effect of fibre reinforcement was analysed in terms of the mechanical properties(tensile,flexural,impact,and hardness)and composite ***,scanning electron microscopy(SEM)was performed on the fibres before and after treatment,and the fractured surfaces of all composite specimens were examined after tensile *** results showed that the 20%DPF/sheep wool hybrid reinforced polyester produced the best *** ultimate tensile strength and modulus were 27 MPa and 3.69GPa,*** ultimate flexural strength and flexural modulus were 35.4 and 2507 MPa,*** impact strength was 39.5 kJ/m^(2)and the hardness was 64 *** density decreased to the lowest value of 1.02 g/cm^(3)with the 30%DPF/sheep wool *** SEM showed good adhesion and interfacial bonding between DPF/sheep wool hybrid fibres and the polyester matrix,particularly at 20%fibre content.
