Evaluation of mechanical and water absorption behaviour of coir and rice husk...eSAT Journals
The document evaluates the mechanical and water absorption behavior of composites reinforced with coconut coir fiber and rice husk powder. Composites were prepared with untreated and NaOH-treated coir fiber at different weight fractions (5%, 10%, 15%) combined with epoxy resin and rice husk powder. Mechanical tests for impact strength and hardness were conducted according to ASTM standards. Results showed untreated composites had higher impact strength and hardness than treated composites due to better fiber-matrix bonding. However, treated composites absorbed less water than untreated composites due to the hydrophobic nature of chemically-modified fiber. In conclusion, untreated composites performed better mechanically while treated composites were more resistant to water absorption.

Abstract Natural fiber composites are nowadays being used in various engineering applications to increase the strength and to optimise the weight and the cost of the product. Various natural fibres such as coir, sisal, jute, coir and banana are used as reinforcement materials. In this paper both treated and untreated banana fiber are taken for the development of the hybrid composite material. The untreated banana fiber is treated by sodium hydroxide to increase the wettability. The untreated banana fiber and sodium hydroxide treated banana fiber are used as reinforcing material for both Epoxy resin matrix and Vinyl ester resin matrix. Coconut shell powder is used along with both untreated and treated banana fiber as a reinforcing material. In this process the banana fiber is treated with 5% of sodium hydroxide for one hour and the specimen is fabricated by hand moulding process. The mould used for fabricating the hybrid composite material is made up of aluminium with a debonding agent applied on the inner side. The banana fiber content is kept constant to 30% of weight fraction of entire composite material. The variation in mechanical properties are studied and analyzed. Here, the tensile strength has calculated by universal testing machine, impact strength has calculated by pendulum impact tester and flexural strength has calculated by universal testing machine with flexural test arrangement of the specimen. Then the treated and untreated specimens are analyzed and compared through Scanning Electron Microscope to study about its adhesion between fiber and resin matrix and surface morphology.

2. ABSTRACT
• In the contemporary world, natural fibers reinforced polymer composite (NFRPC) materials are of great interest owing to their eco-
friendly nature, lightweight, life-cycle superiority, biodegradability, low cost, noble mechanical properties.
• The researchers are facing numerous challenges regarding the developments and applications of NFPRCs due to the inherent
characteristics of natural fibers (NFs).
• These challenges include quality of the fiber, thermal stability, water absorption capacity, and incompatibility with the polymer matrices.
• Interfacial bonding between the fiber and matrix plays a vital role in deciding the mechanical characteristics of composites.
• The current aerospace and automotive industries are looking to change the conventional materials which are high density material to
composite material for reducing the overall weight of the vehicle to increase its performance.
