Development of sustainable and biodegradable materials: A review on banana and sisal fibre based polymer composites

Abstract

Natural fibres are biodegradable materials that contribute to the development of a “green” economy due to their numerous merits such as energy efficiency, ease of manufacturing, environmental friendliness, low cost, sustainability, and biodegradability. Natural fibres have lately become more appealing to technology and innovation as substitute materials for synthetic fibre-based composites due to these qualities. Several projects have also been undertaken to reveal the potential applications, economic and environmental benefits of natural fibres sourced from plants for polymer reinforcements. Among the commonly used fibres are banana and sisal fibres which form part of the reasons for their selection in this review. The justification for this is the environmental concerns in the modern days which have increased the demand for natural materials as suitable alternatives for synthetic reinforcements. Hence, this review reveals the impact of banana and sisal fibres as reinforcements in polymers on the environment, the possible future processing pathways, and applications.

Optimizing Biomedical Facilities Performance with Dombeya Fiber-Paper Particle Hybrid Reinforced Epoxy Composites

“…The impact strength of the developed materials is presented in Figure 9, where a congruent tendency was observed, similar to the mechanical properties in Figures (6)(7)(8). The impact strength exhibited a discernible trend, showing casing variations in the energy absorption with changing reinforcement concentrations.…”

“…These fibers, derived from natural sources, possess noteworthy attributes such as strength, lightweight, costeffectiveness, and biodegradability. The constituents of plant-based natural fibers are primarily hemicellulose, cellulose, and lignin, with varying percentages depending on plant type and geographical location [6]. Natural fibers represent a highly promising resource that is utilized as a material for a wide range of applications that are not limited to automotive, light construction, thermal insulation, cosmetics, medicine, and fine chemicals.…”

“…Natural fibers can be categorized into two types depending on the nature of the source: renewable and nonrenewable. These fibers can be derived from animals or plants [6], [9]. Some research has been conducted utilizing natural fibers as reinforcement materials embedded in an epoxy matrix for biomedical applications.…”

Sustainable natural biopolymers for biomedical applications

“…By replicating the structure of natural fibers and utilizing biopolymers derived from renewable sources, biocomposites are now poised to be incorporated into everyday consumer products. 39,40 However, despite the numerous advantages associated with natural fibers, such as their widespread availability, non-toxic nature, combustibility, and biodegradability, [41][42][43][44][45] their practical utilization faces challenges arising from variations in quality, the requirement for low processing temperatures, and increased moisture absorption. 46 In response to these limitations, researchers have dedicated significant efforts to the functionalization of natural fibers, with the goal of creating advanced biopolymer composites strengthened by natural fibers.…”
