Study on FGNF/epoxy Composite Fabricated by Using Centrifugal Slurry-Pouring Method | Chapter 4 | New Approaches in Engineering Research Vol. 6

Casting process was used to create functionally graded natural fiber/epoxy (FGNF/epoxy) cylinders hybrid composite in this work. The natural fibres (NF) employed in this investigation were coir husk and empty fruit bunch (EFB). The composite's mechanical characteristics and microstructure were determined. Three various pouring heights and NF compositions were evaluated, namely 150, 250, and 300 mm and sample 1 (80% epoxy, 10% coir husk, 10% EFB), sample 2 (80% epoxy, 15% coir husk, 5% EFB), and sample 3 (80% epoxy, 5% coir husk 15% EFB), respectively. Epoxy cylinders, on the other hand, contain 100% epoxy and were made from scratch (sample 4). The hardness, density, and compression tests were used to describe the FGNF/epoxy cylinders that were manufactured. The NF particles can be graded from the upper to lower surface of the FGNF/epoxy cylinders by casting, according to the findings. Many NF particles were localised in the centre and bottom of the composite rather than the top. Due to changes in NF composition around the cylinder, the hardness and density values range from the highest at the lower surface to the lowest at the upper surface, as shown by the hardness and density test results. Natural fibre particles slide downhill by gravity during casting due to a variation in density of NF. Sample 1 and sample 2 had the highest and lowest Young's modulus, respectively, according to the compression test results. FGNF/epoxy has a greater Young's modulus and yield strength than a pure epoxy cylinder composite. The homogeneous composite appears to be superior to FGNF/epoxy with a gradient in NF composition.
