Effect of moisture absorption and chemical treatment on the properties of natural fiber reinforced polymer composites: An assessment

In recent years, Hybrid composites were advanced through the usage of different types, shapes, and sizes of reinforcement. The fillers and matrix used in these composites were chosen for their synergistic qualities.. Natural fibres, on the other hand, have a number of drawbacks, including limited dimensional stability, low thermal stability, and high moisture absorption, severely limit their potential for use as polymer reinforcement. Natural fibres have a low resistance to water absorption, which is one of their biggest drawbacks. This has negative consequences for fibre mechanical characteristics and dimensional stability, and leads to embrittlement over time, which is linked to the hydrolysis of the macromolecular skeleton. As a result, it's critical to investigate the water absorption behaviour in depth in order to determine not only the potential implications of the absorbed water, but also how this water absorption might be reduced in some way. They are biodegradable, do not contaminate the environment in any manner, have high mechanical, thermal, and tribological capabilities, and have good tensile strength and durability. Tensile strength, impact strength, compressive strength, and so on are examples of mechanical qualities, while tribological properties describe the material's wear and tear or abrasive properties. Natural fibres are long-lasting, although their qualities in the presence of moisture vary depending on the medium and procedure used to extract them. Different natural fibres absorb moisture at different rates and behave differently once they've absorbed it. The purpose of this research is to look at how moisture absorption and chemical treatment affect the characteristics of natural fibre reinforced polymer composites.
