Mechanical Characteristics of Sisal/Al<sub>2</sub>O<sub>3</sub>/Epoxy Hybrid Composites

This study examines the impact of Al 2 O 3 particles on composites made of sisal and epoxy. A unique combination of hand lay-up and compression molding procedures are used to fabricate the Sisal/Al 2 O 3 /epoxy hybrid composites, with different weight percentages of Al 2 O 3 particles of 0%, 1%, 2%, and 3%. The produced sisal/Al 2 O 3 /epoxy hybrid composites' flexural, tensile, and compressive properties are then correlated with water absorption studies. The sisal/epoxy composites have undoubtedly been affected by the Al 2 O 3 particles, which have improved their mechanical and physical properties. Compared to other composite samples, the sisal/2wt.%Al 2 O 3 /epoxy hybrid composites show superior flexural, tensile, compressive, and water absorption resistances. Therefore, the optimal combination of hybrid sisal/Al 2 O 3 /epoxy composites can prominently improve the properties, making them a viable alternative for a variety of industrial applications.
