Abstract

This research focuses on the preparation and characterization of natural fiber filled asphalt based damping material (FDM) which are normally viscoelastic material and have behavior in between elastic solid and viscous fluid.Current used damping material mostly consist of synthetic materials which are normally non-biodegradable,low cost efficiency and promote the emission of carbon.Thus,natural fibers are getting their position as reinforcement.The objectives of this research are to fabricate,characterize and study the physical and mechanical properties of FDM by density measurement,heat resistance test,optical microscopy,thermo-gravimetric analysis,dynamic mechanical analysis and Oberst Beam Method test.This research involves the production and characterization of FDM with different kenaf fiber loadings.The FDM composites are produced through mechanical mixing and hot pressing process.FDM samples are then subjected to physical and mechanical characterization.From this research,the characterization and analysis results have shown that FDM with 10% kenaf fiber loading provides the best damping performance among all the FDM composites (0 ~ 15%) under atmospheric temperature.For damping performance,FDM with 10% fiber loading gained the highest dynamic modulus and loss factor in Dynamic Mechanical Analysis and Oberst Beam Method test.FDM with 10% fiber loading also showed the less weight loss due to thermal degradation as compared to other FDM composites.
