Preparation and Characterization of Whole Stem Kenaf Fibre-Poly (Butylene Adipate Co-Terephthalate) Composites

This study focused on the preparation and characterization of whole stem kenaf (WSK) fibre with poly(butylene adipate co-terephthalate) (PBAT) by melt blending technique. The biodegradable composite were prepared at 10, 20, 30, 40 and 50% weight of fibre loading using internal mixer. The blending pr...

For the untreated fibre, the results show that tensile strength remained constant as filler loading from 10% to 30%, but increased at 40%. The properties of composites on flexural and impact strength were decreased with the increasing of the fibre loading.

Thermogravimetric analysis (TGA) confirmed the removal of hemicelluloses and lignin from WSK fibre after treatment. The DMA indicates that the storage modulus of the composites increase with the increased of the fibre loading but decreased after 40% fibre loading.
