摘要

This study focuses in natural fibre, extracted from the fruit of a new species of palm (Borassus aethiopum M.), as a potential reinforcement. The chemical, morphological, physical-hygroscopic, thermal, and mechanical properties of fibre, obtained through biological retting in stagnant water, were examined by using methods such as those of Technical Association of the Pulp and Paper Industry (TAPPI), scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analysis (TGA), and its derivative (DTG). TAPPI analysis reveals a chemical composition of 39.51 wt% cellulose, 28 wt% hemicellulose, and 36.1 wt% lignin. The FTIR spectrum confirms the presence of hydroxyl groups (O–H), C-H bonds, and C = O bonds, corresponding to celluloses, hemicelluloses, and lignin, respectively. SEM images display recognisable hollow individual fibres characterised by their lumens and thin walls. Gravimetric analyses indicate water absorption of 108.65 ± 6.1 wt% after 24 h and moisture content of 12.43 ± 1.1 wt%. Fibre exhibits an average diameter of 164 ± 36.6 µm, a linear density of 9.4 tex, and a density of 1.26 ± 0.09 g.cm−3. TG/DTG reveals thermal stability up to 225 °C. Tensile tests show an average tensile strength of 115.9 ± 54.3 MPa, Young’s modulus of 1.3 ± 0.9 GPa, and an elongation at break of 34 ± 10.4%, comparable to other natural fibres recently identified like promising reinforcements. Weibull analysis indicates a moderate dispersion in strength related to structural defects. This study highlights the potential of Borassus aethiopum fibre as a sustainable alternative to synthetic fibres, creating up opportunities for applications in textiles, packaging, and lightweight automotive materials.
