“…In recent times, there has been a growing interest in sustainable biocomposite products driven by consumer demands and environmental organizations worldwide. − The escalating levels of carbon dioxide (CO 2 ) in the atmosphere pose a substantial threat, necessitating the urgent utilization of biobased natural resources as alternatives to CO 2 -emitting sources. − Despite the wide-ranging applications of polymeric materials, discontinuing the production of plastic materials derived from thermoplastic, thermosetting polymers, and rubber is challenging. − Additionally, composite manufacturing industries heavily rely on petroleum-based resources. , In this context, exploring carbon-based materials sourced from nature presents a viable alternative. − Poly(lactic acid) (PLA) has emerged as a promising and popular bioplastic due to its monomer’s derivation from natural sources like corn, making it a renewable and biodegradable polymer. ,, PLA exhibits higher tensile strength and Young’s modulus compared to synthetic polymer-based plastics, enhancing its competitiveness. − However, it possesses inherent brittleness, heat resistance, and limited crystallization capabilities, hindering its potential applications. − Nevertheless, with suitable physical or chemical modifications, PLA can be considered a carbon-neutral thermoplastic polymer.…”

Sustainable polymeric blends were successfully produced by blending biobased poly(propylene 2,5-furan dicarboxylate) (PPF) with poly(lactic acid) (PLA). This study aimed to enhance the toughness of PLA, which is known for its inherent brittleness, by incorporating compatible polymeric additives. In this regard, a biosynthesized PPF polymer was used to strengthen PLA, resulting in improved tensile properties and the potential for biodegradability, as both PLA and PPF are derived from natural sources. The study revealed that the highest tensile strength (89.46 ± 2.98 MPa) was achieved with a 30% PPF reinforcement of PLA, while the greatest elongation at break (63.85 ± 4.10%) was observed with a 20% PPF reinforcement, compared to neat PLA. Additionally, the 30% PPF reinforcement of PLA exhibited a significantly higher Young's modulus of 3197.35 ± 107.25 MPa. All the blends displayed superior tensile strengths and elongation at break compared to neat PLA. Tensile strengths showed an increasing trend with a higher content of PPF copolymers. Morphological investigations indicated limited compatibility between PLA and PPF, but this characteristic did not negatively impact the thermo-mechanical performance of the developed blends. Furthermore, the thermal stability of the blends increased with a higher loading of PPF in the polymeric blend system. Overall, these sustainable composite products demonstrate promising potential for applications requiring enhanced mechanical and thermal properties. The results suggest that the developed blends are suitable for scalable production and real-life applications.

“…They tested several types of natural fibers such as hemp, kenaf, and sisal fibers, and compared them to glass fibers as a conventional reinforcement. The results showed that natural fibers have relatively high tensile strength and a decent modulus of elasticity, making them an attractive alternative to glass fibers in several applications [4]. [5], [6], [7] explored the use of composites with bamboo fiber reinforcement in construction applications.…”

The insect Callosobruchus maculatus, is responsible for serious damages in the storage of grains of diverse cultures, among them, the one of the beans. Therefore the development of substances capable of being an alternative to minimize agricultural losses and thus contribute to food security of the population is a current necessity.This research aims to explore new materials derived from natural fibers for the development of environmentally friendly and recyclable medical devices, particularly prostheses. The focus is on utilizing ramie fiber, a natural fiber, as a substitute for artificial fibers and plastics in composite materials. The study investigates the impact and bending strength of ramie fiber composites by varying the volume fraction and fiber orientation. The experimental design involves three volume fractions (1%, 3%, and 5%) and three fiber orientations (10°, 20°, and 30°). Hand lay-up method is employed on molds, ASTM D256 impact tests and ASTM D7264 bending tests are conducted to assess the mechanical properties. The findings indicate that the ramie fiber composite with a volume fraction of 5% and fiber orientation of 30° exhibits the highest bending strength, measuring 471.1 Mpa. Similarly, this composition demonstrates the highest impact strength value of 26,558,720 Pa. Overall, this research contributes to the advancement of sustainable materials for medical prostheses and highlights the significance of optimizing the composition of ramie fiber composites to enhance their mechanical properties.

This study provides a better understanding of reinforcing cylindrical concrete columns (CCC) using a hybrid laminated composite material (HLC) composed of jute and e-glass fibers, including the influence of layer quantity on strength and a comparison with previous research. The utilization of these alternative materials may lead to the development of novel and efficient solutions for constructing durable and robust structures. The primary objectives of this research are to assess the effects of employing HLC as a reinforcing layer on CCC compressive strength, optimize the reinforcement process by selecting appropriate layer sequences and types, and analyze the type of fiber damage in relation to the strength of HLC composite material. The materials utilized in this study encompass woven jute fabric sheets, e-glass fiber sheets, and epoxy resin. Compressive strength testing was conducted following ASTM C39 standards. Specimen variations were based on the number and type of reinforcing layers. The results revealed that CCC compressive strength increased by up to 100% with the application of up to three layers of jute compared to an unlayered specimen. Furthermore, CCC compressive strength experienced a remarkable enhancement of up to 150% with the incorporation of HLC composite. Hence, the implementation of HLC demonstrates significant potential for augmenting the strength of concrete structures.
