“…Despite the benefits offered by NFRPC [10][11][12][13][14], their applications in structural components are restricted. This is due to the naturally occurring irregularities and low mechanical property profile of natural fibers, so that they cannot compete with the glass fiber reinforced polymer composites [15].…”

Natural fibers, such as kenaf, hemp, and flax, also known as bast fibers, offer several benefits such as low density, carbon dioxide neutrality, and less dependence on petroleum sources. Their function as reinforcement in polymer composites offers a great potential to replace a segment of the glass fiber-reinforced polymer composites, especially in automotive components. Despite their promising benefits, they cannot meet the structural and durability demands of automobile parts because of their poor mechanical properties compared to glass fibers. The focus of this research work was the improvement of the mechanical property profile of the bast fiber reinforced polypropylene composites by hybridization with natural high-performance basalt fibers and the influence of basalt fibers coating and polymer modification at the mechanical and thermal properties of the composites. The specific tensile strength of the composite with polymer tailored coating was 39% and the flexural strength was 44% higher than the composite with epoxy-based basalt fibers. The mechanical performance was even better when the bast/basalt hybridization was done in maleic anhydride modified polymer. This led to the conclusion that basalt fibers sizing and polymer modification are the deciding factors in defining the optimal mechanical performance of the composites by influencing the fiber-matrix interaction. The composites were analyzed for their mechanical, thermal, and morphological properties. The comparison of bast/basalt hybrid composite with bast/glass fibers hybrid composite showed a 32% higher specific flexural and tensile strength of the basalt hybrid composite, supporting the concept of basalt fibers as a natural alternative of the glass fibers.

“…It is also worth mentioning that the modification of the polymer is quite an expensive and complicated procedure since it requires additional processing steps and higher material costs. Therefore, it is not usually a preferred method in the industry due to a lack of economic efficiency [12,30,35].…”

“…The use of natural fiber reinforced polymer composites especially in the automotive industry is established and well documented [1][2][3][4]. This is because of the unique properties of natural fibers-such as low density, high specific strength and stiffness, non-abrasive to the equipment during processing, abundant availability, renewability, sustainability, and environmental friendliness [5,6]. Their specific modulus is comparable and at times even better than the glass fibers [6].…”

Hybrid Polymer Composites of Bio-Based Bast Fibers with Glass, Carbon and Basalt Fibers for Automotive Applications—A Review

et al. 2020

Composites with reinforcements based on bast fibers such as flax, hemp and kenaf offer many advantages such as weight reduction, improved specific impact, flexural, acoustic properties, and balanced performance to cost that can be achieved by properly designing the material composition. Their position is well established, especially in the nonstructural automotive applications. However, in structural applications of composites, their mechanical property profile is not comparable to the dominant reinforcements such as glass and carbon fibers. The low mechanical properties of these composites could be improved by hybridization that involves adding high-performance fibers to the bast fiber composites that could improve the low mechanical performance of the bast fiber composites. The review presented in this article provides an overview of the developments in the field of hybrid polymer composites composed of bio-based bast fibers with glass, carbon, and basalt fibers. The focus areas are the composite manufacturing methods, the influence of hybridization on the mechanical properties, and the applications of hybrid composites.

Citrus fruit waste is a potential source for valorisation into pectin. In present manuscript a PolyE‐IL‐1 as an efficient acid catalyst has been integrated for fractionation of pectin from citrus fruit waste. The use of PolyE‐IL‐1 catalyst has specific advantages in term of high yield, ease of catalyst separation, recycle and reuse etc. The process optimization study was conducted to check the influence of catalyst concentration, temperature, time and substrate concentration etc., to obtain maximum yield of pectin. The intensified process yields 30 % pectin at 95 °C in 90 min in batch mode of operation. Moreover, batch reactor, ultrasound batch reactor and microwave batch reactor were compared to observe the influence of the mode of reactor operation. Various citrus waste feedstock (Orange, Sweet lime and Lemon) was tested and maximum yield of (32.52 %) pectin was obtained from Lemon peels. The catalyst recyclability study showed consistency in pectin yield (30 %) for five consecutive recycle runs. Thus, the use of an easily recyclable PolyE‐IL‐1 catalyst provides an efficient route to produce pectin from citrus fruit peel waste.
