ABSTRACT
Natural fibers are of different types of plants, animals, and mineral types. Uses of these fiber-reinforced composites are increasing day by day in daily life applications like in sports, electronics, and automotive industries, etc. Selection of fiber depends on types of matrices used. A matrix may be thermoplastics or thermosets. The main aim of this work is to overview chemical modification of the fiber. There are different types of modification techniques that are used for the treatment of fibers like alkalization, silane, benzoylation, acrylation, permanganate treatment, maleated coupling agent, peroxide treatment, etc., these techniques enhance the roughness between the fiber and matrix due to the removal of hemicellulose and lignin content and resulting increase in different properties like mechanical properties, thermal stability, etc. Composites are prepared for both untreated and treated fiber and compare properties between them and concluded that tensile and flexural strength of treated composites are generally higher than untreated ones.
