“…The Carica papaya fibers were treated with the 5% concentration of NaOH by varying the soaking time from 15 to 90 min at the room temperature. The excess of NaOH from the surface was washed repeatedly using distilled water and was dried for about 56 h. The fibers treated at 60 min with 5% alkaline solution showed the optimum results which showed that complete elimination of hemicelluloses and lignin (Saravanakumaar et al, 2018).…”

The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability, and high specific properties. The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.

“…The most common chemical treatments are alkali treatments, followed by silane treatment, peroxide treatments, etc. [41][42][43][44][45] Athijayamani et al 46 inferred that alkaline-treated fibers in NFRPCs show better dimensional accuracy than composite specimens with other fiber content and treatment method. They concluded in their study that specimen with 30% wt% fiber content and 8 h treatment shows better dimensional accuracy than composites with other fiber content and treatment.…”

“…The same conclusion is also shared with other researches on their comparison between treated and untreated natural fiber with alkali treatment on the mechanical performance of the NFRPCs. 42,44,48,49 However, studies to identify the direct effects of chemical treatment on delamination are still lacking attention. Sathish Kumar et al 50 worked on drilling parameters on NFRPCs with sodium hydroxidetreated jute fiber mat, vinyl ester resin and rigid polyurethane foam.…”

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.

Fillers are utilized for different purposes. In plastic industry, fillers are mainly used to extend the bulk of the compound; however, they can also improve physical properties, materials processing, and reduce cycle time of plastics. In this article, high‐density polyethylene was filled with untreated and 5% alkaline‐treated salago fiber, and thereafter the thermal and nondestructive properties of the composites were investigated. It was found that the chemical treatment of fiber increased the thermal stability and the mean coefficient value of linear thermal expansion of the treated composites as compared to the untreated ones. Moreover, the increase of fiber content in composites increased the crystallinity level while decreased the thermal capacity and melting temperature of the composites. The zinc, calcium, and phosphorus contents were found to be within the industry‐acceptable range for elemental contents in polyolefins. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
