“…A natural fiberreinforced composite exerts the merits such as low density, low cost, easily recyclable and biodegradable in nature, so therefore it is referred to as a potential substitute for manmade fibers. Utilization of natural fibers elicits a comprehensive understanding of surface adhesive cohesion and its chemical composition" [3][4][5]. "Natural fibers are a blend of primary components such as cellulose, hemicelluloses, lignin, wax and pectin.…”

The aim of this work was to study the suitability of wood flour, fluted pumpkin stem and rice husk flour/epoxy bio-composites for application in aquatic environment. The water absorption, thickness swelling and diffusion coefficient of wood flour, fluted pumpkin stem flour, rice husk flour/epoxy bio-composites were investigated. Composites were prepared by the hand layup method at varying weight percentages of filler reinforcement (10, 20 & 30%). The increase in the addition of the fillers enhanced the water absorption, thickness swelling and diffusion coefficient of the composites. However, after 14 days of immersion, all the composites attained an equilibrium state. It was observed that with 30wt% filler loading, the fluted pumpkin stem flour epoxy composites showed the highest water absorption of 40.5%, diffusion coefficient of 10.80x10-8m2/s, followed by the wood flour epoxy composite with water absorption of 35.3%, diffusion coefficient of 8.17x10-8m2/s, while rice husk flour epoxy composites had the lowest water absorption of 16.5%, diffusion coefficient of 6.12x10-8m2/s. The same trend was observed for the composites with 20 and 10 wt% filler loading. In terms of thickness swelling, the wood flour composite showed 1.62%, followed by fluted pumpkin stem flour composite 1.40% and rice husk flour composite 0.35% with 30wt% filler loading. A similar trend was observed for the composites with 20 and 10wt% filler loading. This study can be useful to comprehend the effect of water absorption on the performance of natural fiber composites and help in creating designer compositions for use in building, construction and automotive.

“…Due to their strength-to-weight ratio, low production cost, and eco-friendly and biocompatible nature, highstrength and biocompatible polymer matrix composite materials are in high demand in automobile, aerospace, and defense applications. [1] Typically, a polymer matrix can be toughened in two ways: fiber reinforcement and particle reinforcement. Long continuous natural or synthetic fiber components may be employed in the form of a mat or chopped, whilst bio form of particle or ceramics in the size range of micro to nano could be added to elevate the base qualities of polymer matrix.…”

High toughness epoxy bio-composites were prepared using Caryota urens fiber and biochar particle for light weight and low cost engineering applications.The main aim of this research was to study the effect of adding biochar along with C. urens fiber in epoxy resin composite and its properties. The biochar used in this present study was prepared from coconut shell using pyrolysis process. The composites prepared with 5 vol% of biochar gives highest tensile strength and modulus of 172 MPa and 6.7 GPa. Similarly, the biochar of 7 vol% in epoxy resin reduced the wear volume to the greater extend. Moreover, a highest dielectric constant and loss factor of 6.2, 1.6, and a thermal conductivity of 0.33 W/mK with high hydrophobic contact angle of 70 was observed for composite made using 7 vol% of biochar. These improved dielectric, mechanical, barrier and tribological properties composite could be used as microwave shielding material in electronic gadgets, signal processing units and other telecommunication devices as shielding material with good mechanical properties required.

In this research, the effect of siliconized chitosan biopolymeric particles and morinda fiber in epoxy composite and their mechanical and machining behavior were studied. The primary aim of this research was to investigate how the silane‐treatment influences the surfaces of natural biopolymeric particle and fiber in epoxy composite and to study the mechanical and machining behavior. The chitosan and morinda fibers were surface‐treated using an amino silane 3‐Aminopropyltrimethoxylane (APTMS) via aqueous solution method. The composites were prepared using the hand lay‐up method followed by post‐curing at 120οC. The mechanical results showed that the silane surface‐treated chitosan and morinda natural fiber‐reinforced epoxy composite gives improved tensile, flexural and impact results of 148 MPa, 163Mpa and 6.9 J respectively. The inter‐laminar shear strength of silane‐treated morinda fiber gave the highest value of 28 MPa. Similarly, in the drilling process, the surface‐treated reinforcements showed the highest adhesion with matrix without any delamination. The drilled hole dimension stability at the top and the bottom surface was significantly high for silane‐treated epoxy composites. The scanning electron microscope images revealed high adhesion of fiber and uniform dispersion of chitosan particle in the epoxy matrix. Hence, this study confirms that silane surface‐treatment is an essential process while making high‐performance natural composites for various engineering applications.
