Abstract
This research focuses on the effect of reinforced different types and fiber loading of spent tea leaf fiber (0~20%) on the damping capacity of asphalt-spent tea leaf composites. Composites were fabricated as a viscoelastic sheet material. The objectives of this research are to investigate the effect of different types and spent tea leaf fiber loading on physical properties and acoustic properties of asphalt damping composite material by using the physical and mechanical characterization. The asphalt damping composite materials are fabricated through mechanical stirring and hot compress moulding process. The physical properties were tested through density measurement, cyclic heat resistance test and the interface condition between the mild steel beam and asphalt-spent tea leaf composites were characterized through optical microscope technique. The acoustic properties were tested through Oberst Beam Method analysis. From the analysis and characterisation result, it has revealed that with the increase of either coarse or fine fiber loading are capable to resulting damping sheet samples yield lighter as compared to controlled sample. 15% coarse or fine spent tea leaf fiber loading shows the lowest density among all fiber filled damping material composites (0~20%). Fiber filled damping sheet materials are stable as controlled sample in cyclic heat resistance test and there is no sign of interface delamination or cracking were observed in micrographs of optical microscope. The use of spent tea leaf fiber can improve the vibration damping which shows reduction in frequency peak and reduce vibration transmission with the increase of fiber loading.
