Effect of Al2O3 – 40 wt. % TiO2 ceramic particle size and shape on flexural properties of glass fibre reinforced epoxy composites
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 5
Abstract
The objective of this study is to investigate the flexural properties of glass fibre reinforced epoxy composite filled with different form (fused and crushed, agglomerated), size and proportions of Al2O3 – 40 wt. % TiO2 particles. The composite plates are filled with 0% (unfilled), 5%, 10% and 15% particle weight fractions (based on the weight of resin). Composites are fabricated in conventional hand lay-up technique. Tensile and flexural properties of specimens were determined as per ASTM standards. The results indicate that the tensile and flexural properties of composites are significantly influenced by particle weight fractions, different particle sizes and forms. The results showed that while tensile strength and flexural strength of the composites decreased with increasing Al2O3 – 40 wt. % TiO2 particles content, tensile modulus increased with the Al2O3 particles content. Compared with the flexural properties of the unfilled glass fibre reinforced epoxy composite, with the addition of 5 wt.% of Al2O3 – 40 wt. % TiO2 particle in the matrix, flexural modulus were increased by 7%.
