Comparative analysis of natural fibres characteristics as composite reinforcement

Due to environmental concerns, natural fibre development is essential, and its utilization has recently attracted more attention. The use of jute, hemp, linen, sisal, and banana fibres in textile production is widespread around the world. Additionally, these fibres are widely accessible in many countries, including Pakistan, India, China, Turkey, and the United States. The objective of this study is to compare the physio-mechanical characteristics of the aforementioned natural fibres. All of these fibres were obtained locally. Scanning electron microscopy was used to examine the surface morphology of these natural fibres, and the results revealed that banana and sisal fibres are hollow in comparison to other fibres. A single fibre tensile testing apparatus was used to evaluate the mechanical characteristics. Banana and sisal fibres demonstrated the highest breaking strength and elongation, respectively. Fourier transform infrared spectroscopy was used to investigate the functional groups of these natural fibres. Differential scanning calorimetry and thermogravimetric analysis were used to investigate their thermal behaviour. Energy Dispersive X-Ray Analysis and Raman analysis were also carried out to ascertain the chemical composition.
