Abstract

This research focuses on comparison of empirical and experimental studies on dynamic mechanical behavior of nanocellulose natural fiber in rubber based damping material. The natural rubber is provided by Sunrich Integrated Sdn Bhd and jute fiber is provided by Bangladesh Jute Research Institution. The study aims to determine the damping properties of jute fiber filled natural rubber nanocomposite. The extraction of jute fiber nanocellulose is carried out by through alkaline treatment (8 wt. % NaOH) and acid hydrolysis (3.7 wt. % HCl). The chemical functional groups of jute fiber before and after chemical treatment has been characterized by using Fourier Transform Infrared Spectroscopy (FTIR). The 2.5 wt. %, 5 wt. % and 10 wt. % jute fiber nanocellulose/natural rubber composites · have been fabricated. The formulation of jute fiber rubber nanocomposites have been identified. The different jute fiber loading of natural rubber composites were then placed inside the internal mixer and undergo vulcanization using 50 ton hydraulic press. The damping properties of different jute fiber loading of rubber-based damping material have been analyzed through Dynamic Mechanical Analysis. An attempt has been made to correlate the experimental and theoretical values of storage modulus. Guth equation and Einstein's equation have been used to evaluate the comparison storage modulus of different jute fiber loading rubber composites obtained from DMA by experimental studies. The use and limitations of theoretical equations to predict the storage modulus of the jute fiber nanocellulose/natural rubber have been discussed
