The utilization of natural fibre-reinforced polymer composites has been tremendously growing in various applications of automotive and aerospace components. In this aspect, the researcher’s community is approaching the global market with new ideas for developing a complete eco-friendly, sustainable, and green composite. Plant-based composites have received great interest from the initial stage due to their unique features, such as lightweight, corrosion resistance, specific properties, excellent mechanical and thermal properties. This research article attempts a novel technique of coating the fibres with polylactic acid (PLA) as a part of surface modification which improves fibre properties. Then the fibres were reinforced with various weight percentages of conductive fillers, such as Copper (Cu), Alumina (Al2O3), and Graphene (Gr), to improve the electrical properties using the hand layup technique. Then the fabricated samples were tested for dielectric and electromagnetic interference (EMI) shielding effectiveness (SE) using resonance and open shielded method. Based on the test results, it was noted that the dielectric strength (K) and shielding effectiveness (SE) of the composites started to increase with the increase of weight percentage of conductive fillers, which highlighted that by incorporating conductive fillers, the fibres started losing their insulation properties. The composites with 0.9wt.% of nanofillers achieved maximum SEabs of -19.61dB and a SEtotal of -22.67dB at a frequency range of 8-12GHz.

“…At the same time, compared with the matrix material, plant fibers tend to have higher mechanical strength, so in the sliding friction process of composites, plant fibers attached to the surface of the polymer hinder the wear and removal of matrix material, and the coefficient of friction decreases with the increase of fiber content. 155 Compared with the pure matrix, during the friction process, tiny fragments of plant fibers are worn down to fill the micropores generated on the surface of the composites, which enhances the friction resistance. 156,157 For the research of friction and wear of composites, the molding method of composites is mainly the compression molding process, [158][159][160][161][162] and the injection molding process 155 is insufficiently researched.…”

Resource depletion and environmental degradation have become important issues affecting the human development process. Plant fiber‐reinforced composites (PFRCs) are characterized by high natural availability, good mechanical properties, low density, recyclability, and eco‐friendliness. Expanding human applications of plant fibers is an important measure to combat resource and environmental problems. The injection molding process has the characteristics of strong product size adaptability, high molding precision, and high production efficiency. It is suitable for large‐scale production in the industry and is one of the main molding methods of PFRCs. Currently, there are still challenges and opportunities for high‐performance manufacturing of PFRCs based on the injection molding process. This article reviews the complete process of manufacturing‐service life‐remanufacturing of PFRCs based on the injection molding process. Emphasis is placed on the pretreatment technology and selection strategy of multi‐phase blended raw materials, the molding process conditions, functional applications, and simulation analysis, the aging and degradation characteristics during service, and the remanufacturing characteristics of the composites. Finally, the future research focus is summarized and prospected. The research in this paper will help promote the continuous progress of key technologies in the production process of PFRCs and help the industry to truly realize high‐performance green manufacturing in the future.Highlights Plant fibers exhibit variability in morphology and properties. The link between the structure and performance of PFRCs is unclear. The degradability and durability of PFRCs are contradictory. The functionality and mechanical properties of PFRCs are contradictory. PFRCs have good characteristics for remanufacturing.

This study explores the synergistic influence of hybridizing titanium oxide (TiO2) filler on the mechanical properties and sliding wear behavior of epoxy composites reinforced with hairy cotton grass (HCG) fibres. The experimental results reveals that the combination with 9 wt‐% HCG/4 wt‐% titanium oxide observed better mechanical results (tensile‐51.03 MPa, flexural‐28.66 MPa, and impact energy‐3.1 J) whereas higher hardness (40.77 HV) achieved at 9 wt‐% hairy cotton grass/6 wt‐% titanium oxide composites. There is deterioration in mechanical results at higher titanium oxide (6 wt‐%) loading due to uneven distribution and particle agglomeration in hairy cotton grass‐epoxy composites. The design of expert was generated by using control parameters, sliding velocity (1 m ⋅ s−1–4 m ⋅ s−1), TiO2 content (0 wt‐%–6 wt‐%), and normal load (15 N–30 N) respectively. The optimization of the sliding wear rate was analysed by the Taguchi approach followed by an analysis of variance used for evaluating the significant of control parameters. The results showed a combination with significance sliding velocity of 1 ms−1 (78.15 %)>titanium oxide content of 6 wt‐% (20.28 %) >normal load of 30 N (1.57 %) exhibited an optimum value of specific wear rate.
