Chapter 12 - Kenaf fibers, their composites and applications

Abstract

Natural fibers have been used since the beginning of civilization. The fibers extracted from Kenaf plant (Hibiscus cannabinus L.) is advantageous and possess high potential to be used as reinforcement in composite materials. Natural fibers such as kenaf are given more importance recently by researchers and industries owing to the demand for sustainable manufacturing practices and eco-friendly products. Kenaf fibers have the capability to replace the conventional synthetic fibers used in polymer composites due to its comparable specific properties. The mechanical and thermal properties of Kenaf fiber reinforced composites in its original form, chemically treated and hybridized form has become suitable for variety of structural and non-structural applications in industries. Apart from its use as reinforcement in polymer composites, its long fibers extracted from the bark and bast are effectively used as reinforcements in building construction materials. In this chapter, the recent explorations in use of Kenaf fibers as reinforcements in composite materials, its manufacturing methods, chemical modifications, hybridization and its properties for several applications were portrayed. Kenaf fiber reinforced composites with corrosion resistance and non conductive behavior extensively finds use in automotive, electrical, packaging, construction, agricultural, acoustic, ballistic and marine applications.
