Cold Glow Discharge Nitrogen Plasma Pretreatment of Banana Fibre for Improving the Mechanical Characterisation of Banana/Epoxy Composites

摘要

Abstract Natural fibers are naturally supple and have various properties depending upon their chemical composition and physical aspects. Banana fiber is a derivative of the processing of the “banana plant’s pseudostem” (Musasepientum) the current research on the application of natural fiber composites has shown that the physical treatment of fibers improves their adherence to matrices. This works aims to investigate the effect of Cold glow discharge nitrogen plasma treatment on Musa sapientum (banana) fiber to modify the interfacial bonding of fiber-matrix, with cold glow discharge nitrogen plasma treatment 80?W (30?min) and 120?W (30?min) was being utilized. To improve the interfacial strength of banana fibers, induce a sufficient transfer of stress between the matrix and fiber. The cold glow discharge nitrogen plasma treatment 80?W (30?min.) of banana fiber provided the banana fiber reinforced epoxy composite(BFREC) has been found to have improved nearly 81.79 higher interlaminar shear strength, 66.16 higher flexural strength, and 57.54 higher tensile strength. To estimate the morphological characteristics for cold glow discharge nitrogen plasma treated banana fiber and untreated banana fibers performed by FT-IR spectroscopy and (XRD), which showed the improved fiber surface structure, better mechanical and tribological properties can be obtained, broaden the scope of green materials for industrial applications.
