“…These alternatives have motivated authors, and this is one of the reasons for the popularity of this topic worldwide. This has also helped identify a large variety of agro-sources since the use of coconut fibers isolated from the residue of cultivars from India [40], Malaysian bagasse residues produced during the sugar cane juice extraction [35], Nigerian African star apple (Chrysophyllum albidum) residues [41], or Indi.an Cymbopogon flexuosus residues after oil extraction [42]. These strategies support the reduction of organic charge derived from the final disposition of agro-waste [43] or food waste and promote the implementation of green and circular economy strategies with a positive economic impact on the income of farmers.…”

“…These evaluations have been predominant since 1982 and are mainly related to flexural and tensile tests. For tensile testing, researchers have attempted to establish the effects of untreated and treated natural fibers on the composite behavior [30,41,62,63,70,71,84,89,91,103,105]. Additionally, other types of tensile testing based on the evaluation of a single fiber or few fibers embedded in the matrix are useful for evaluating the matrix wettability, fiber/matrix adhesion, and efficiency of the fiber treatment [109].…”

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.

“…33 The improvement of the mechanical properties of the composites after alkali treatment was due to the removal of non-cellulosic substances on the surface of the particles and a better interfacial bonding between the alkali-treated particles and the matrix. 50,53 But the matrix's ability to wet the filler affects the tensile strength, 54 and 3A3AT has weaker mechanical properties than 0A3AT because ATP and rough WS particles after alkali treatment increased the specific surface area of fillers, the encapsulation of PVC to fillers reduced, and the internal interface of the composites was discontinuous, which finally lead to the decrease of the mechanical properties of the composites. On the other hand, the shape and particle size of fillers affected the agglomeration tendency and strength of fillers in composites, 52,55 ATP and rough WS particles formed mechanical adhesion in the mixing process and lead to reinforcement agglomeration and stress concentration.…”

In order to reveal the effect of alkali treatment of walnut shell (WS) powder and attapulgite (ATP) hybrid filling on the properties of WS/polyvinyl chloride (PVC) composites, and to compare the effects of different reinforcement methods, WS/PVC composites were prepared by single screw melt extrusion. Furthermore, analysis was conducted on the chemical composition, thermal stability, microstructure, and physical, mechanical and wear resistance properties of composites. The results showed that ATP hybrid can enhance the performance of WPC more effectively than alkali treatment, unmodified WS blended with ATP composites have the best physical, mechanical properties, abrasive wear resistance, as well as lower water absorption, compared with the untreated, the tensile strength, bending strength and impact strength increased by 24%, 8%, and 21%, respectively. In addition, the composites of ATP hybrid alkali treated WS have the best thermal stability, and its pyrolysis residue is 15.64% higher than untreated composites. The study found that ATP have a larger potential to enhance the properties of composites than alkali treatment.Highlights Chemical treatment and inorganic mineral particle filling were used to enhance the properties of the WS/PVC composites. The experimental results showed that attapulgite can maximize the properties of the composites without alkali treatment. This means that attapulgite filling is a more effective and environmentally friendly and simple method to enhance the properties of composites than alkali treatment. The wear failure modes of the composites are mainly micro‐indentation and micro‐cutting.

Bu çalışmada çözelti döküm yöntemi ile elma kabuğu ve/veya mikrokristalin selüloz katkılı polilaktik asit esaslı filmler üretildi. Filmlerin yapısal, mekanik ve optik özellikleri karakterize edildi. Katkı maddelerinin eklenmesi, saf PLA filmlerin çekme dayanımı ve esnekliğini arttırırken, şeffaflığını biraz azalttı. PLA biyokompozit filmlerinin başarılı üretimi, çevre dostu ambalaj malzemeleri olarak kullanılma potansiyeline sahip olduklarını gösterdi.
