The important issue in composite technology is the interfacial strength between the fiber and matrix. The strong bonding in the interfacial region is essential for achieving high mechanical performances of biocomposites. Therefore, a number of chemical and physical treatment studies on a variety of natural fibers have been devoted to understand and enhance the interfacial adhesion between the natural fibers and the polymer matrix and to further improve the composite properties. In the present study, sodium hydroxide was independently used as fiber surface treatment media. Ultrasonic technique can be utilized as a dynamic treatment to understand the basic mechanism in chemical treatment of natural fiber. Ultrasonic velocity, and density have been measured in the aqueous solutions of Cellulose with sodium hydroxide, with a view to understand the nature of interaction between the cellulose and sodium hydroxide at temperature 303K. The acoustical parameters such as adiabatic compressibility, intermolecular free length, acoustic impedance are calculated. These parameters provide valuable information regarding achieving of high mechanical performances of natural fiber. The SEM and FTIR data of untreated and treated date palm fiber clearly shows the improvement of surface of date palm leaf.
