Study of Hybrid Composites using Measurements of Ultrasonic and Some Physical Properties

The huge deposition of industrial waste and by-product of different agricultural waste in open environment of many regions of India are creating the new environmental problems day by day. The composite materials made from industrial waste or bio-waste has found to be less significant than that of hybrid one. The hybrid composite using coir dust and fly ash particle reinforcement were prepared with proper treatment of blended chemicals by ultrasonic technique. The optimized value of blended chemicals proves its importance in synthesis of better hybrid composite rather than that of unknown proportions of chemicals. The different physico acoustic properties like dielectric constant and sound absorption of synthesized composites has been measured. The results of dielectric measurement and sound absorption property of this material ensures the importance of hybrid composite rather than single composite. The resulting composite property shows that the injection of coir dust and fly ash into it helps in the interface bonding and distribution of absorbed moisture in the material producing a change in dielectric behavior.
