Examining the effect of permanganate (KMnO4) on bamboo fiber (Bambusa vulgaris) reinforced with bio-resin natural honey (melitera) and pawpaw (Carica papaya) leaves extract
Abstract
Bamboo fibers are modified for improved interfacial bonding and reduction of moisture absorption. This is achievable through various treatments. The bamboo fiber's mechanical and chemical properties were examined with a Tensile machine and FTIR instrument. Natural fibers have many advantages over manufactured fibers like low density, low cost, biodegradability, poor compatibility between them and the matrix, relatively high moisture sorption, etc. The treatments are vital to modify the surface properties. For this, potassium permanganate (KMnO4) was used in this study. The Fourier transform Infra-red (FT-IR) analysis of untreated bamboo fiber showed the presence of the Hydrogen-bonded (O-H) stretch, H-C-H asymmetric and symmetric stretch, C-H stretch of C=O, C≡N stretch, N=O Bend, and C-O stretch. For the treated bamboo fiber, the analysis shows similar results. Similarly, results of reinforced bamboo fiber showed hydrogen-bonded O-H stretch, C-H stretch of C=O, C≡C stretch (C-O stretch), N=O stretch, and N-H bend. The treated Bamboo fiber was reinforced with a bio-resin (natural honey and pawpaw extract). Mechanical testing was done to get the tensile strength at increased concentration, and FT-IR was used to get the effects of chemical treatment on the fibers. Potassium permanganate treatment improved the properties with increased concentrations.
