dc.description.abstractThe purpose of this study is to examine and characterization of the mechanical and physical characteristics of glass reinforced with sisal fiber that has been filled with Al2O3. Due to their exceptional performance and customized qualities, fiber reinforced materials are extensively utilized in a wide range of engineering applications. These days, particular fillers and additives are added to composite materials to lower material prices, increase and adjust the composites' quality to some extent, and in certain situations, improve the product's performance and capacity to be processed. The creation, characterization, and examination of the mechanical and physical characteristics of a polyester hybrid composite reinforced with glass-sisal fibers and Al2O3 is the goal of this research. It also aims to evaluate the hybrid composite suitability for wind turbine blade material applications. In the present work Aluminum Oxide (Al2O3) with different weight fractions (0, 2, 4, 6, 8 and 10wt %) were studied .The HFRC samples are prepared using the hand lay-up method followed by light compression loading. The experimental results shows that the addition of Al2O3 improved the mechanical properties of the HFRC, with the optimal composition being 6% Al2O3, 22% glass fiber, 12% sisal fiber, and 60% polyester. This composition showed the highest tensile strength (93.66 MPa), flexural strength (176.29 MPa), and impact strength (22.17 kJ/m²). It also had the lowest water absorption (3.26%) and density (1.22 g/cm³).The experimental results were also analyzed using ANSYS software. The ANSYS analysis showed that the optimal HFRC composition could withstand the static loads that wind turbine blades are subjected to. Based on the experimental and ANSYS results, the HFRC with 6% Al2O3, 22% glass fiber, 12% sisal fiber, and 60% polyester has the potential to be used as an alternative material for wind turbine blades material.
