The increasing trend of the use of synthetic products may result in an increased level of pollution affecting both the environment and living organisms. Therefore, from the sustainability point of view, natural, renewable and biodegradable materials are urgently needed to replace environmentally harmful synthetic materials. Jute, one of the natural fibers, plays a vital role in developing composite materials that showed potential in a variety of applications such as household, automotive and medical appliances. This paper first reviews the characterization and performance of jute fibers. Subsequently, the main focus is shifted towards research advancements in enhancing physical, mechanical, thermal and tribological properties of the polymeric materials (i.e., synthetic or biobased and thermoplastic or thermoset plastic) reinforced with jute fibers in a variety of forms such as particle, short fiber or woven fabric. It is understood that the physio-mechanical properties of jute-polymer composites largely vary based on the fiber processing and treatment, fiber shape and/or size, fabrication processes, fiber volume fraction, layering sequence within the matrix, interaction of the fiber with the matrix and the matrix materials used. Furthermore, the emerging research on jute fiber, such as nanomaterials from jute, bioplastic packaging, heavy metal absorption, electronics, energy device or medical applications and development of jute fiber composites with 3D printing, is explored. Finally, the key challenges for jute and its derivative products in gaining commercial successes have been highlighted and potential future directions are discussed.

“…The market for natural fibers was already worth billions of dollars in 2017 9 . However, the large‐scale use of natural fibers also raises concerns about waste generation and environmental degradation 10 . Especially in recent years, there has been a global focus on carbon neutrality and reducing carbon dioxide emissions, 11 which has led to increased attention on reusing or recycling natural fiber waste to lower carbon emissions.…”

Corrosion resistance and durability are always considered in the safety design of composite materials. In this study, recycled jute woven fabrics from coffee bags were used to fabricate jute/unsaturated polyester composites. The effect of water absorption and pre‐drying treatment on the long‐term hydrothermal aging behavior of the prepared composites, as well as the aging mechanism, was discussed. The hydrothermal aging test was performed at a fixed temperature of 80°C for specified conditioning times of 24, 120, 240, 480, and 720 h. Weight gain and weight loss values were recorded and compared. The mechanical properties were evaluated using a three‐point bending test and observations of the fracture area. The results showed similar water uptake and flexural behaviors between the composites with different pre‐drying treatments, especially after long‐term hydrothermal aging. It was also found that the moisture diffusion of the composite followed a Fickian process, and the flexural properties of the bending specimens at every position reduced with the aging time and initially decreased rapidly during the first 24 h of aging. In particular, the reduction rate in flexural properties generally followed the sequence of NO.1 > NO.2 > NO.6 > NO.5. Additionally, the aging mechanism study revealed three steps for the composites during the water absorption process. The inclusion of jute fiber as a composite material in this research provides insight into the water‐absorption mechanism of jute fabric‐reinforced polymer composite (JFRP).Highlights Recycled jute fabric‐reinforced composites were produced using jute fabrics obtained from recycled coffee bags. The effect of the water absorption track and pre‐drying treatment on the long‐term hydrothermal aging behavior of recycled jute fiber‐reinforced composite and its aging mechanism is discussed. The clarification of the aging mechanism indicates that there are three steps involved in the water absorption process. Considering jute fiber as a composite could help explain the water‐absorbing mechanism of JFRP.

“…Comparisons of cost and environmental impacts for real manufacturing scenarios with synthetic and natural fibers are also possible [20]. Further LCA studies on biocomposites conclude that adding natural fibers to replace all or part of synthetic fibers demonstrates a lower environmental impact on that component [12,21,22].…”

Comparison of Structural Performance and Environmental Impact of Epoxy Composites Modified by Glass and Flax Fabrics

2022

Comparing the structural performance and environmental impact of parts made of natural and synthetic fibers has become increasingly important for industry and education, as the benefits of one type of fiber over another are not always clear. The current work discusses the advantages and disadvantages of using natural and synthetic fibers and compares the flexural performance of parts made of each of these fibers and their environmental impact. This paper investigates the flexural behavior of epoxy composites modified by glass and flax fabrics through experimental, numerical, and analytical studies. Specimens with various fabrics (dried and non-dried) were fabricated to test their performance. The failure of unidirectional glass and flax fiber reinforced polymer composite laminate was examined by destructive testing. A finite-element model was developed, and the mechanical behaviors of fiber-reinforced composites were predicted in a three-point bending test. Experimental results were compared to numerical analysis to validate the model’s accuracy. A life cycle assessment (LCA) was employed to determine the climate impact of composite production. The analysis revealed a decreased environmental effect of plant-based panels suggesting that they are less energy and CO2 intensive than synthetic solutions. The LCA model can be applied in further studies of products that consist of or use flax-based composites.
