“…However, these fibers are part of a broader variety, because this category corresponds to 76% of the identified natural fibers. UPR biocomposites are also an opportunity to find additional alternatives to fibers that are more common in the local market, but with less impact globally, such as the Tunisian alfa fiber isolated by the esparto grass [44][45][46], called the Stipa tenacissima plant, Brazilian native curaua [47], and Colombian fique fibers [48].…”

Unsaturated polyester resin (UPR) is one of the first commercialized polymer matrices for composites reinforced with glass fibers, but has remained popular to this day. To reduce their environmental impact, natural fibers have been used as reinforcements. Researchers all over the world are still interested in these composites, and numerous papers have been published in the last four decades. Using bibliometric analysis, this work provides compiled, structured, and relevant information about the evolution and current state of these materials. This first study on UPR biocomposites based on bibliometric analysis examined 531 published papers identified in the Scopus database from 1982 to July 2022. An analysis of the most active states, leading institutions, and leading authors is followed by the identification of key areas such as the most common natural fibers used as reinforcements, fiber treatments, and composite design parameters such as processing techniques; recently, composite testing; and technological applications. The findings emphasize the importance of staying active in this global field and provide information on novel promising topics for future research.

“…However, compared with metals, concrete, and composite materials, the mechanical properties (strength and toughness) of natural wood are not ideal in many advanced engineering structures and applications. A large number of studies on improving the comprehensive properties of wood pointed out − including chemical treatment of most lignin and hemicellulose, − densification treatments (hot pressing or impregnation), and heat treatments. , Lignin is removed with an aqueous solution of sodium hydroxide and sodium sulfite, the specific strength of the wood obtained after hot pressing is comparable to that of metal, and it can be used as a bulletproof material. Lignin in the wood is completely removed with an aqueous solution of sodium chlorite, and then the resin is impregnated to obtain a transparent wood that can replace glass.…”

Wood is a green, environmentally sustainable, high-performance structural material that is an attractive candidate to replace nonenvironmental structural materials. However, the mechanical performance of natural wood is generally insufficient in many advanced engineering structures and applications. Herein, we report a simple and effective strategy in a new type of green-enhanced wood development to synthesize a high mechanical biomass structure material from renewable wood resources. In this process, the lignin of the natural wood is partially removed, and the hard cell walls become pliable and easy to handle. After treatment, the wood fiber structure is preserved, and the wood fibers are closely arranged after densification, which shows the reinforced wood with high mechanical properties. The resulting reinforced wood is 8 times stronger than the starting wood and comparable to widely used structure materials such as concrete, stainless steel, aluminum alloy, and magnesium alloy. This method of manufacturing reinforced wood with green, rich, and renewable natural wood is extremely attractive for the sustainable development of engineering structural materials, which broadens the potential of wood as structural materials.

Environmental concerns and the depletion of petroleum resources have spurred research into natural fibres as sustainable alternatives to synthetic fibres as the reinforcement phase in polymer composites. Given that the local availability of materials is a crucial component in the sustainability framework, there is a need to map out the fibres used to develop natural fibre composites across geographical regions to optimize local resource utilization. Through a systematic review of publications sourced from Scopus and Web of Science databases, this study examines the contributions made by Africa to develop green polymer composites. The bibliometric data from both databases were systematically merged, and bibliometric analysis was carried out to identify trends and relevant relationships and provide a more general insight into Africa's progress in the natural fibre polymer composite field. A meta‐analysis was then conducted to identify the natural fibres exclusively sourced from Africa that have been used to develop polymer composites. The study also discussed natural fibre classifications with respect to fibre type and form. Sisal, palm varieties (particularly date palm), alfa, jute and members of the Musaceae family (i.e., banana, plantain and enset) were found to be the most used African‐sourced fibres. This study is a step to creating a more extensive global natural fibre database that seeks to provide more precise knowledge, enhance research efficiency, and ensure the utilization of local materials in creating more sustainable composites.Highlights The use of local materials is a key component of sustainable development A natural fibre database can foster sustainability in the composite industry Egypt, Morocco, and Tunisia are leading Africa's composite research Research prioritizes composite material science over practical applications Sisal, date palm, alfa and jute are the most used natural fibres in Africa
