Development of biodegradable composite micro-perforated panel made from natural fibre composites with evaluation of its acoustic and mechanical properties
Micro-perforated panel (MPP) has been widely considered as a promising alternative for sound absorption purposes. Plenty of research has been done to improve the sound absorption of MPP but no specific work highlights the material structure effect towards its sound absorption performance. MPP...

| description | Micro-perforated panel (MPP) has been widely considered as a promising alternative
for sound absorption purposes. Plenty of research has been done to improve the sound
absorption of MPP but no specific work highlights the material structure effect towards
its sound absorption performance. MPP is mostly made from metallic or plastic
materials which does not exhibits any pores or tortuous structure and therefore,
material structure issue is often being eliminated from analysis. In order to study the
material structure effect, alternative material must be used to fabricate MPP.
Numerous research found that natural fibre possesses excellent sound absorption
properties due to its porous and tortuous structure. Yet, natural fibre has low tolerance
towards mechanical processing and thus binder must be incorporated to overcome this
shortcoming. This thesis basically describes the development process of biodegradable
composite micro-perforated panel (BC-MPP) made from natural fibre (kenaf, wood,
and coconut) and polylactic acid (PLA) composites. BC-MPP samples were fabricated
with different material composition percentage of natural fibre and PLA. The effect of
material composition percentage, perforation ratio, perforation diameter, and air cavity
thickness were investigated. The effect of material structure towards the sound
absorption performance of BC-MPP sample was studied. It has been found that
existence of pores and tortuous structure can indeed influence the sound absorption
performance of BC-MPP sample. The sound absorption performance of BC-MPP
sample was compared to conventional MPP and it has been found that BC-MPP
possessed better sound absorption performance courtesy to its porous and tortuous
structure. BC-MPP sample also possessed better tensile strength compared to common
sound absorption panel such as medium density fibreboard, hardboard, commercial
ceiling board, and plywood. |
