Abstract

Waste cooking oils are problematic disposal especially in the developed countries. In this paper, waste cooking oil is used as raw material to produce foam. The purpose of the study is to develop the high density solid biopolymer foam (HDB) by using hot compression moulding technique based on flexible and rigid crosslinking agents. Physical properties such as Scanning Electron Microscope (SEM) and vibration characteristics have been studied via vibration transmissibility test according to ASTM D3580-95 standard. By using the linear vibration theory with single degree of freedom, the resonance frequency of vibration transmissibility and damping ratios of HDB foam at variation excitation are acquired. The results show that HDB flexible foam gives higher damping ratio to absorb vibration. The different thicknesses were examined during the fabrication of (HDB) to measure the vibration property. The decreasing of HDB flexible foam thickness gives increasing of the damping ratio up to 36%.
