Bifunctional Aluminum Oxide/Carbon Fiber/Epoxy Nanocomposites Preparation and Evaluation

Abstract

Aluminium oxide was designed and synthesised with three different diamines, including production and/or diamino diphenyl sulfoxide, as well as p-phenylenediamine, to improve the adhesion properties of lightweight carbon composites. For 3-ply composite production, manual lay-up was utilised as a straightforward process. The fibre content ratios of 30:70 with fibre inclinations of 0, 45 and 90 degrees were employed in sample processing. Both Al2O3 and many fibre layers were first distributed in the epoxy coating and then the Al2O3 and carbon-strengthened epoxy were immediately inserted into that same carbon fibre to increase the mechanical properties. The Al2O3 and fibre glass compositions ranged from 0.1 to 0.5%wt. The mechanical qualities of hybrid composites are found to be primarily determined by the kind of derivatization, followed by the proportion of altered Al2O3. As a consequence, the Al2O3 additive dramatically improves both flexural and tensile forces. Because of Al2O3 good mechanical properties, both tensile strength and flexural strength and elastic modulus are boosted by Al2O3 filling inside the adhesives.
