In the Bayer process of extraction of alumina from bauxite, the insoluble product generated after bauxite digestion with sodium hydroxide at elevated temperature and pressure is known as red mud' or bauxite residue'. Enormous quantity of red mud is generated worldwide every year posing a very serious and alarming environmental problem. With increased environmental threat it has become necessary to find out alternative uses of industrial wastes and to develop value added products using them. This book is a step in that direction. A possibility that the incorporation of both particles and fibres in polymer could provide a synergism in terms of improved properties. The present book includes the processing and evaluation of mechanical properties of red mud filled coir fibre reinforced polymer composites. The systematic experimentation leads to determination of mechanical properties at various percentages of fibres with red mud as filler material. The buckling analysis of prepared composite is also done experimentally as well as in ANSYS to determine the effect of fibre and red mud loading on composite material.
