Abstract: Durian skin is a newly explores natural fibre
potentially reinforced polyolefin for diverse applications. In this
work, investigation on the effect of coupling agent, maleic anhydride
polypropylene (MAPP) on the mechanical, morphological, and
thermal properties of polypropylene (PP) reinforced with durian skin
fibre (DSF) was conducted. The presence of 30 wt% DSF
significantly reduced the tensile strength of PP-DSF composite.
Interestingly, even though the same trend goes to PP-DSF with the
presence of MAPP, the reduction is only about 4% relative to
unreinforced PP and 18% higher than PP-DSF without MAPP
(untreated composite or UTC). The used of MAPP in treated
composite (TC) also increased the tensile modulus, flexural
properties and degradation temperature. The enhanced mechanical
properties are consistent with good interfacial interaction as
evidenced under scanning electron microscopy.
