Machining parametric study on the natural fiber reinforced composites: A review

Abstract

Nowadays, the utilization of natural fiber reinforced composite has increased frequently. These natural fibers have significant features like low cost, renewable, and, more importantly, biodegradable in nature, making them to be utilized for various industrial sectors. However, the massive demand for natural fiber reinforced composites (NFRC), forces them to be machined and operated, which is required for countless areas in multiple industries like automotive, marine, aerospace and constructions. But before obtaining the final shape of any specimen, this specimen should come across numerous machining processes to get the desired shape and structure. Therefore, the present review paper focused on the various aspects during conventional and unconventional machining of the NFRC. It covers the work by exploring the influence of all input variables on the outcome produced after machining the NFRC. Various methodologies and tools are also discussed in this article for reducing the machining defects. The machining of the NFRC is found as a challenging task due to insufficient interlocking between the matrix and fibers, and minimum knowledge in machining characteristics and appropriate input parameters. Thus, this review is trying to assist the readers to grasp a basic understanding and information during the machining of the NFRC in every aspect.

Assessment of thrust force, delamination and temperature during drilling of basalt fiber-reinforced composite with different drill geometries

“…Therefore, DG also has an important influence in determining drilling quality in composite materials, according to the research results. Additionally, the optimal selection of machining parameters, including drill diameter, feed rate (FR), and spindle speed (SS), as well as the manufacturing method employed for composite production, fiber volume fraction, and fiber orientation, is imperative to ensure the creation of damage free holes [6][7][8][9][10].…”

Effect of gamma irradiation on the waste polyethylene/bagasse composites reinforced with flax and sisal fibers for use in wood applications

“…Lately, the employability of natural fibers as reinforcements in composites has been approved by many researchers. 5,6 Multiple factors, including rising environmental concerns, possible cost competitiveness, oil decline and costs, and new rules for a safer and cleaner environment, 7,8 are driving this growth in interest in natural fiber compounds. The use of natural fibers instead of conventional reinforcements like glass fiber and carbon fiber has been proven to have significant environmental benefits because their composites are biodegradable.…”
