In recent years, with greater emphasis on environmental and sustainability aspects of engineering materials, natural fiber-reinforced polymer composites (NFRPCs) have gained significance in practical applications because of their numerous advantages. Although many researchers have developed NFRPCs using various types of natural fibers and matrix materials, in real-world applications of NFRPCs, secondary operations, such as milling and drilling, are necessary to complete the components or parts assembly. Because the drilling of NFRPCs is different from drilling of metals, there are concentration of studies interested in the aspects of drillability of NFRPCs in order to assess and understand issues related to drilled hole quality in NFRPCs. In this paper, a comprehensive review of factors that affect the drilled hole quality in NFRPCs is presented. Past researches where correlation between the manufacturing methods of NFRPCs and drillability of the composites are reported are reviewed in-depth. The novelty of this review is that it identifies the major factors that affect the quality of the drilled features from a composite manufacturing perspective and provides recommendations for the best NFRPCs manufacturing process to produce drill-friendly composites. The major factors were classified into composite manufacturing factors and drilling parameters factors.

Fiber Reinforced Polymer Composites

The applications of natural fiber composites have enormously increased due to the high availability, eco-friendly nature and practical applications of the composites. In this review different fiber combinations using natural fiber and synthetic fibers have been investigated and found with interesting results. The hybrid nature of fiber reinforcement adds to the mechanical properties of polymer-based composites. The hybridization using more than one fiber reduces the surface deformations in the polymer matrix and enhanced the bonding ability of polymer composites. The alkali treatment was the effective surface treatment process for improving the cellulosic nature with good crystalline nature, good bonding ability with the polymer matrix, this adds to the properties of polymer-based composites. The crystallinity index of 43-68 % were observed in surface treated natural fibers.

Fiber Reinforced Polymer Composites

This paper deals with tensile properties of natural fiber reinforced polymer composites. Natural fibers have recently found increasing use in various fields as an alternative to synthetic fiber reinforced polymers. Due to this they have become attractive to engineers, researchers and scientists. Natural fibers are replacing conventional fibers such as glass, aramid and carbon due to their eco-friendly nature, lesser cost, good mechanical properties, better specific strength, bio-degradability and non-abrasive characteristics. The adhesion between the fibers and the matrix highly influence the tensile properties of both thermoset and thermoplastic natural fiber reinforced polymer composites. In order to enhance the tensile properties by improving the strength of fiber and matrix bond many chemical modifications are normally employed. In most cases the tensile strengths of natural fiber reinforced polymer composites are found to increase with higher fiber content, up to a maximum level and then drop, whereas the Young’s modulus continuously increases with increasing fiber loading. It has been experimentally found that tensile strength and Young’s modulus of reinforced composites increased with increase in fiber content [1].

Fiber Reinforced Polymer Composites

In recent years, researchers and scientists are facing problems in terms of environmental imbalance and global warming owing to numerous use of composite materials prepared by synthetic fibers and petrochemical polymers. Hence, an increasing attention has been devoted to the research and development of polymer composites reinforced with the natural fibers. The natural fibers are the most suitable alternative of synthetic fibers due to their biodegradability, eco-friendliness and acceptable mechanical properties. The natural fibers are attracting the researchers and scientists to exploit their properties by amalgamating them with the polymer. The properties of natural fiber reinforced polymer composites mainly depend upon various factors such as properties of fibers and matrices, fiber loading percentage, size and orientation of fibers, stacking sequences, degree of interfacial bonding, fiber surface treatments, hybridization and incorporation of additives and coupling agents. Tensile and flexural tests are the most important investigations to predict the applications of the materials. A good number of research has been carried out on tensile and flexural properties of natural fiber reinforced polymer composites. In this paper, a review on tensile and flexural properties of natural fiber reinforced polymer composites in terms of effects of fiber weight fraction, geometry, surface treatments, orientations and hybridization is presented. Moreover, recent applications of natural fiber reinforced polymer composites are also presented in this study.

Reinforced Thermoplastics

Natural fiber reinforced polymer composites (NFRPC) are conventionally processed in compression molding process to shell-shaped components, which are mostly used in automotive industry. Therefore, natural fibers (NF) and polypropylene (PP) as matrix system are processed to a thermoplastic organic sheet. Organic sheets are heated in a contact heating press to temperatures above melting temperature of the matrix and then transferred to a forming press. In this paper, Acrodur®Power 2750 X (AP) is used as an alternative to PP. This thermoplastic matrix system enables an increase of fiber content to 75 wt.-% in NFRPC. Furthermore, infrared radiation (IR) with adapted wavelength was used as an alternative to conventional contact heating. To improve the heating behavior of NF/AP infrared and heat transfer additives were used. By adding heat transfer additives and using IR heating with adjusted wavelength, both heating time can be reduced from 45 seconds (NF/PP) to 25 seconds (NF/AP) and a contact heating press can omitted.

Processing Properties

Increasing scientific interest has occurred concerning the utilization of natural fiber-enhanced hybrid composites that incorporate one or more types of natural enhancement. Annual natural fiber production is estimated to be 1,783,965 × 103 tons/year. Extensive studies have been conducted in the domains of natural/synthetic as well as natural/natural hybrid composites. As synthetic fibers have better rigidity and strength than natural fibers, natural/synthetic hybrid composites have superior qualities via hybridization compared to natural composites in fibers. In general, natural fiber compounds have lower characteristics, limiting the use of natural composites reinforced by fiber. Significant effort was spent in enhancing the mechanical characteristics of this group of materials to increase their strengths and applications, especially via the hybridization process, by manipulating the characteristics of fiber-reinforced composite materials. Current studies concentrate on enhancing the understanding of natural fiber-matrix adhesion, enhancing processing methods, and natural fiber compatibility. The optimal and resilient conceptions have also been addressed due to the inherently more significant variabilities. Moreover, much research has tackled natural fiber reinforced hybrid composite costs. In addition, this review article aims to offer a review of the variables that lead to the mechanical and structural failure of natural fiber reinforced polymer composites, as well as an overview of the details and costings of the composites.
