“…As output parameters, surface roughness, kerf taper angle, and material removal rate will also be the focus of this survey, as well as the phenomenon of delamination, a summary of the relationship between these two and input parameters. It is noteworthy that the AWJM uses erosion to remove the target material, so there is no contact between the cutting tool and the material, and there are no high impact defects of cutting forces related to delamination damage [ 13 , 18 ], but strength of NFRPs machined by AWJM gets affected, so the tensile strength is somewhat lesser than the composites cut by traditional methods [ 13 ].…”

“…[ 2 , 4 , 6 , 7 , 8 ]. Although the NFRP composites are manufactured near-net shape, they still need some final cutting processes to reach the shape required such as drilling, cutting, and trimming processes [ 9 , 10 , 11 , 12 , 13 , 14 ]. Composite materials do not behave like conventional materials under different cutting processes, because of their different properties.…”

Recently, natural fiber-reinforced polymers (NFRPs) have become important materials in many engineering applications; thus, to employ these materials some final industrial processes are needed, such as cutting, trimming, and drilling. Because of the heterogeneous nature of NFRPs, which differs from homogeneous materials such as metals and polymers, several defects have emerged when processing the NFRPs through traditional cutting methods such as high surface roughness and material damage at cutting zone. In order to overcome these challenges, unconventional cutting methods were considered. Unconventional cutting methods did not take into account the effects of cutting forces, which are the main cause of cutting defects in traditional cutting processes. The most prominent unconventional cutting processes are abrasive waterjet (AWJM) and laser beam (LBM) cutting technologies, which are actually applied for cutting various NFRPs. In this study, previously significant studies on cutting NFRPs by AWJM and LBM are discussed. The surface roughness, kerf taper, and heat-affected zone (HAZ) represent the target output parameters that are influenced and controlled by the input parameters of each process. However, this topic requires further studies on widening the range of material thickness and input parameter values.

“…These reinforcements have proved to be the best in respect to the mechanical strengths and durability. 33,34 A research on the influence of lanthanum salt treatment on the poly- p -phenylenebenzobisoxazole FRPs revealed that the surface treatment enhanced the amount of polar groups and improved the adhesive bonding between the fibre and matrix as a result, the friction coefficient and wear rate are considerably alleviated. 35 The addition of micro-sized particles in the composite matrix enhances the resistance to friction and wear.…”

The dominance of fibre-reinforced plastics in industries has enhanced the need for research to develop new composites and assess their properties. Among the various property analyses, tribological characteristics of the composites help to understand the friction and wear behaviour. This article presents a comprehensive survey on the tribological behaviour of polymeric composites, which includes the influence of various working parameters such as the velocity of sliding, sliding distance, pressure applied and temperature on the friction and wear. The article also addresses about the importance of the composite constituents such as fibre composition, fibre geometry and fibre orientation on the tribological behaviour. The major reasons causing the tribological failure like the debonding between the fibre and the matrix, failure of the matrix and the fibre are also extensively addressed. This review would be an insight to the industries and tribology researchers towards achieving optimum design for the components made of polymers.

“…Extensive reviews on static mechanical, [10][11][12] tribological, 13,14 dynamic mechanical thermal analysis, 15 machining, 16 flammability and flame retardant properties, 17 of NFRC are found at literature database, but review on vibration damping studies of natural fiberreinforced composites is not yet reported. To the best of our knowledge, this would be the first attempt to bring together the vibration studies, by experimental and numerical methods, on natural fiber-reinforced thermoset and thermoplastic polymer matrix composites to promote the researchers and industrialist towards vibrational response of NFRC.…”
