Green Resins from Plant Sources and Strengthening Mechanisms

Green composites from natural fibers and biopolymers: A review on processing, properties, and applications

“…Composites are engineered materials fabricated by implanting one constituent into another in a dispersed or controlled arrangement to exploit the synergistic performance of the multiples. 107 The combination necessarily has at least two elements and for fiber-reinforced polymer composites (FRPCs), one is polymer-based matrix while the other is fiber, yarn, or fabric added mainly for withstanding greater mechanical stress or extension of shelf life. 21,29,91 When natural fibers are embedded in a matrix from biopolymers like corn, starch, cellulose, or proteins for compositing, the product is essentially classified as green composite.…”

“…236 Being non-biodegradable at the same time, they are finally adding up to the environmental impacts in the landfill also. 98 For this reason, fully green composite is burdened with a set of preconditions like it must degrade and decompose by the action of air, light, heat, microorganisms or other environmental factors without leaving adverse impact 107,237 and the sourcing of both the matrix and reinforcement will be from renewable sources without encouraging carbon positivity as much as possible. Therefore, the domain for the selection of resin and fibers consequently narrowed down, and yet within this domain, many of the explored resins proved not to be suitable 238 while others, as well as the fibers, are associated with many undesirable performance barriers.…”
