“…The moisture absorption dropped from 70 to 41% with increasing the BF content from 0 to 60%. Figure 8 shows a comparison between the moisture absorption of the TPS composites reinforced with 60 wt% fibers at the equilibrium plateau from the previously stated studies [13][14][15][16]. From Figure 8, it can be concluded that the moisture absorption is highly dependent on the fiber type, hence the cellulose content of the fibers.…”

“…For flax, bagasse, banana, and date palm fiber (DPF) preparation took place by preheating the composite, pressing at 5 MPa and 150°C for 30 min [13][14][15][16]. Bamboo-reinforced starch composite was prepared by pressing at 20 MPa and 130 C for 5 min [17].…”

“…Each type of fibers has its own cellulose content; thus fibers with high cellulose content highly diminish the moisture absorption of the resultant composite. Mehanny et al [13] studied the effect of reinforcing thermoplastic starch (TPS) matrix with different contents of NaOH-treated bagasse fiber on the moisture absorption of the resultant composite. Figure 5 shows the moisture absorption of composites reinforced with 0, 20, 40, 60, and 80% bagasse fiber.…”

“…The thermogravimetric graph for thermoplastic starch matrix is shown in Figure 11. The authors in references [13][14][15][16] reported that the thermal decomposition of thermoplastic starch occurs in three main steps. The initial weight loss that occurred in the TGA curve between room temperature and 100°C represents the first step.…”

“…Furthermore, the reinforcement of lignocellulosic fibers significantly improves the mechanical properties of starch-based matrix [10]. Sisal, jute, kenaf, coir, wood, pulp, cellulose, bagasse, banana, orange, and flax fibers are lignocellulosic fibers that have been all studied and found to substantiate enhancement for the starch-based matrix's versatile properties [10][11][12][13][14]. The objective of this article is to review and conduct further analysis to understand the effect of high-fiber content (flax, palm, banana, bagasse, bamboo, and hemp) on mechanical and physical properties.…”

Natural source-based composites became promising substitutes and synthetic petrochemical-based counterparts. So far, thermoplastic starch and lignocellulosic fibers are the most common materials for making such eco-friendly "green" materials. Low cost, abundance, and renewability are the factors that lead to deploying these two types of materials. In this chapter, we are conducting further analysis for previously published results of six types of high-content natural fiber-reinforced starch-based composites. All composites were prepared by compression molding under pressure from 5 to 20 MPa and temperature from 130 to 160°C. Composites exhibited highest tensile strength and modulus of elasticity at fiber weight content from 50 to 70%, and then mechanical properties deteriorated significantly at 80% fiber content due to the insufficient starch resin. For instance, the tensile strength was boosted up from 2-12 MPa for thermoplastic starch to reach 55,45,32,28,44, 365 MPa for flax, bagasse, date palm fiber (DPF), banana, bamboo, and hemp composites, when fiber content was increased from 0% to the optimum fiber content (50-70%). Kelly-Tyson (random 2d) was the optimum model to predict random fiber composite. Increasing the fiber content and choosing a fiber with high cellulose content significantly improve the moisture resistance of the composites. Fick's law of diffusion predicted the water uptake property successfully. The thermal stability of composites was improved with increasing the fiber weight content as well. This is attributed to the high thermal stability of cellulose when compared to starch. Properties exhibited by starch-based high-content natural fiber composite are promising for many industrial and biomedical applications.

This study aims to synthesize and characterize a bioresin named cardanol from cashew nutshell liquid and use it to create novel polymer composites. Sisal fibres were dried out in an oven to reduce humidity. These fibres were then cut into 15 mm lengths and chemically treated using an alkaline process. Compression moulding was used to make polymer composites of cardanol reinforced with 15% wt% 15 mm sisal fibre and bentonite nanoclay (with nanoclay levels of 0%, 1%, 3%, 5% and 7%). Fourier transform infrared spectroscopy was used to characterize the bioresin cardanol. The mechanical behaviour for cardanol nanocomposites was assessed using tensile, flexural and impact tests and a water absorption test. Furthermore, the thermal and morphology behaviour of cardanol nanoclay composites was examined. The results confirm that increasing the range of nanoclay by up to 5% enhanced mechanical characteristics. © 2023 Society of Industrial Chemistry.
