A Comprehensive Survey on Machinability and Mechanical Properties of Natural Fiber Reinforced Polymers

Natural fiber reinforced polymer composites (NFRPs) has attracted much attention as a cheap and environmentally friendly solution. The survey explores the machining and mechanical properties of NFRPs (especially those that contain natural fibers like jute and hemp). The results of the deep cryogenic treatment effect on the cutting tool employed in machining these composites are examined concerning the tool wear, tool life, cutting force as well as the surface finish. Environmental analysis measures the static and dynamic mechanical properties, tensile strength, flexural strength, and hardness. Also, the tribological behavior of the composites is assessed in terms of the coefficient of friction and wear rate in order to determine how the composites perform during the machining process. The paper also discusses the optimisation of machining processes through statistical means like ANOVA, in order to increase productivity and tool life. The results open a new direction in the machinability of NFRPs to their wider use in sustainable processes.
