Description 526-533
The present work investigated the influence of natural fibers in Kevlar-reinforced epoxy composite. In this research, four
layers of Kevlar woven fiber are fabricated by hand layup technique. In each sample, three layers of natural filler are filled
between the Kevlar fabric layer. Three samples are fabricated, and each sample is added either with eggshell powder,
Banana Bract, Human hair, which is reinforced with epoxy resin 10:1 ratio. The characterization of mechanical and thermal
behavior evaluated by tensile, flexural, thermal conductivity, heat deflection, and water absorption is analyzed by ASTM
standards. Mechanical fractured surface and interfacial adhesion layer formation are analyzed in Scanning electron
microscopy. The result shows that eggshell powder-filled Kevlar epoxy composite exhibits higher mechanical properties
than the other two epoxy composite filled with either human hair or banana bract. Human hair-filled Kevlar composite had
better mechanical properties than banana bract composite. The study of the morphological structure shows that Eggshells
and human hair-filled composite have less water absorption, high heat resistance, low thermal conductivity. This fabricated
composite can be utilized for ship fuel tank covers, valve covers, lining materials of marine constructions.
