Effect of variable ultrasonic frequencies on some physical properties of Iraqi palm fiber PVA composite

Abstract The palm fiber –PVA composite polymer membrane were prepared by solution casting method with different ratios of concentration in order to study the ultrasonic frequency affect on mechanical properties of this composite. Ultrasonic pulse technique of variable frequency (25,30,35,40,45 and 50 kHz)
