| Abstract: | Natural fibres have become an
important element in producing alternative fibrereinforced
composites. The use of natural fibre for
sound absorber material has recently investigated.
This study investigates the use of rice-husk waste
as the potential element for sound absorption
material of rice-husk reinforced composite. The
rice husk is initially cleaned and dried up at room
temperature (25 - 30 ºC). The dried rice husk is
then mixed together with Polyurethane (PU) foam
as a binder to produce the rice husk reinforced
composite. Six different samples have been
produced according to the percentage of rice husk.
The specimens were tested using an impedance
tube. The result found that the best percentage of
rice husk was obtained at 25 percents. The sound
absorption coefficient obtained demonstrated that
the mixture produced the best performance at low
frequency region. The results also demonstrated
that the rice husk reinforced composite have a
better sound coefficient compared to other natural
materials, hence promising a great potential for
commercialisation. |
