Abstract

Bio-based materials play a significant role in developing efficient engineering materials because of availability, recyclability and eco-friendliness. Products from Borassus flabellifer are found in both urban and rural locations in Bangladesh, and its fruits, leaf stems, and leaves are utilised in domestic applications, while some, mainly the fruit shells (husk), are discarded as agricultural waste. The objective of this study was to characterize the physical and chemical properties of the Borassus husk fibre experimentally, and it has been found that the density of the husk fibre is 0.74 g/cm 3 , water absorption is 47.25%, moisture regain is 4.41%, and porosity is 34.58%. While scanning electron microscopy (SEM) outcomes show cross-linked, non-uniform, and cylindrical-shaped tubular fibre, fourier transform infrared spectroscopy (FTIR) shows the presence of hemicellulose, cellulose, lignin, and other components. Hence, this can be used as an alternative potential natural fibre for lightweight engineering designs.
