Wood Flour Filled Thermoset Composites


Wood Flour Filled Thermoset Composites

M. Ramesh, L. Rajeshkumar

The increasing environmental concerns, health related issues and depletion of fossil fuels have led to an increased interest in the development of eco-friendly bio-degradable and sustainable materials. The development of sustainable and renewable materials from natural resources has been witnessing a tremendous world-wide attention and importance. In recent years, there has been a continuous and emerging research in the preparation of novel materials from wood based resources due to their great potential as alternatives to petroleum-based products. Wood flour based composite is recognized as sustainable materials owing to its eco-friendly attributes derived from reinforcement of fully degradable wood fibers etc. which leads toward minimization of the generation of polluting agents. The aim of this chapter was to develop sustainable composites by complete replacement of the synthetic fibers by sustainable wood flour and substituting thermoset matrices. This chapter discusses the fabrication methods of wood flour based composites, and its properties in detail. From the analysis it is observed that physical and mechanical properties of the composites are greatly influenced by the fibre loading and the concentration of wood flour. The practical applications of these composites are also discussed at the end of the chapter.
