Abstract

A study has been carried out to investigate the viability of palm oil male flower spikes (POMFS) fiber reinforced polyurethane composite to be implemented as sound absorption panel. The composite panels were fabricated with increment of POMFS fiber weight percentage of 5 wt%, 10 wt%, 15 wt%, 20 wt% and 25 wt%. The samples were also fabricated in three different thicknesses which are Smm, 25 mm and 35 mm. The acoustics characteristics were investigated by using two microphones method for low and high frequency. The physical characteristics of the composite such as density and porosity were also been tested. The samples were also tested for mechanical characteristics with compressive test. The results demonstrate some potential characteristics of palm oil male flower spikes fiber reinforced polyurethane to be implemented as sound absorption panel.
