Abstract

<jats:p>Reinforcement with natural fibre has become a common place in a range of industries in the modern day. A polymer matrix can, however, boost the strength of the reinforcing element. When it comes to natural fibres and polymers, they simply do not mix because of their different hydrophobic and hydrophilic properties. However, because the polymer matrix is designed to be hydrophobic, the natural fibres are hydrophilic. This issue can now be rectified with alkalization and a silane binding agent. This technique of modifying natural fibres may result in both rise in surface roughness and a reduction in water attraction and moisture content. In this research, the effects of alkaline and silane treatment were demonstrated using mechanical testing and Fourier transform infrared spectroscopy (FTIR). DSC and TGA tests were used to assess the materials’ chemical compositions and thermal properties. In comparison to other composites, those with a 2 percent silane treatment showed improved strength performance. Hemp fibre composites are expected to achieve great performance in industrial applications by enduring chemical treatment.</jats:p>
