DETERMINING SOUND ABSORBTION COEFFICIENT OF NATURAL FIBER REINFORCED POLYPROPYLENE COMPOSITES

Natural fibers are those include those produced by plants, animals and geological process around the surroundings of living organisms. They are mainly degradable throughout their life cycle. The former are mainly used in the process of the automobile manufacturing sector, which enhances the durability and life cycle with greater efficiency. The main purpose of this paper is to overcome all the sound emission problems inside the automobile passenger compartments by finding the sound absorption coefficient of various samples by introducing a new range of combination of composites that are environmental friendly. The congenial benefits may in turn be useful for the future testing in the field of development of automobile industries which enhances the rate of qualitative products for the customers in demand.
