| description | A novel biocomposite where both natural fibre and matrix are derived from underutilized parts of
sugar palm tree was successfully developed. This 100% green materials can lead to solve depletion
and non degradable polymer waste disposal problems. Unfortunately, since moisture absorption is
a matter of concern in biocomposites, the effect of water absorption on mechanical properties of
sugar palm fibre reinforced sugar palm starch (SPF/SPS) composites has been studied. From this
investigation, it can be seen that tensile and impact strengths of biocomposites increase with the
increase of fibre content. This enhancement indicates the effectiveness of the SPF to act as reinforcement
for composites. But the mechanical properties of the biocomposites dropped after being
stored for 72 hours at RH = 75%. In general, the weight gain due to water absorption of all biocomposites
linearly increased with the increase of square root of immersion time and it tends to be
more constant after a 48 h, following a Fickian diffusion process. Furthermore, moisture absorption
decreased with the increase of sugar palm fibre (SPF) content. SEM micrographs showed good
dispersion and adhesion between sugar palm starch (SPS) and SPF but large cracks appear on
the surface of the matrix (SPS) due to water absorption. |
