Natural fibers are biodegradable materials that are innovatively and widely used for
composite reinforcement in automotive components. Nanocellulose derived from natural
fibers oil palm empty bunches have properties that are remarkable for use as a composite
reinforcement. However, there have not been many investigations related to the use of
nanocellulose-based composites for wideband sound absorption materials. The specimens
of nanocellulose-based polyester composite were prepared using a spray method. An …
