Development And Investigation on Sugarcane/ Silicon Carbide Fillers and Glass Fabrics Reinforced Hybrid Polymer Composites for Aircraft Structure

Abstract

To improve the physical, mechanical, and thermal properties of the polymer composite, sugarcane bagasse fibre, polyester resin, sodium hydroxide, potassium hydroxide, glass fibres, and HCl are used as reinforcement materials in the current study. The mechanically assisted wet layup process was used to create the polyester hybrid polymer composites. A scanning electron microscope was used to view the samples' microstructure. It was found that incorporating silicon carbide and sugarcane bagasse powder into the polymer improved the composites' mechanical and thermal properties. It can be attributed to the fillers' and polyester polymer's greater interaction and homogeneous distribution. To improve the properties of polyester hybrid composites, fillers were essential. For each specimen, the properties of water absorption were also examined. A comparison of a few manufactured composite specimens was done. Results showed that adding reinforcements significantly enhances the composites' ability to absorb water. The most notable increase in tensile, flexural, and impact strength is provided by silicon carbide plus sugarcane bagasse reinforcement, which is around 2.84, 1.65, and 9.19 times better than pure polyester polymer. The polymer hybrid composites have improved thermal stability, as demonstrated by thermogravimetric analysis and differential scanning calorimetry. Scanning electron microscopy was used to examine the uniformity of filler dispersion within the polymer.
