Abstract
Development of ecofriendly biocomposites to replace non-biodegradable synthetic fibre composites for
optimum performances is the main objective of this study. To highlight biocomposites as suitable
replacements, polyethylene terephthalate matrix composites reinforced with blended water retted and
surface alkali treated Entada Mannii fibre particulates and carbonised tropical almond shell ash (TASA)
were synthesized by mould casting. The efficacy of water retting as a means of extracting fibres from
Entada Mannii plant and fibre modification using NaOH of varying concentration on the mechanical properties of Entada Mannii fibre particulates – PET composites were investigated. Mercerization enhanced
the surface properties of Entada Mannii fibres and thus led to better bonding between it and the matrix.
Hybrid composites from untreated Entada Mannii fibre particulates and tropical almond shell exhibited
the highest hardness of 41.09 BHN. 4% NaOH treated fibre particulate hybrid composites exhibited tensile
strength (4.795 MPa), flexural strength of 6.09 MPa, hardness value of 37.63 BHN, and impact energy of
21.49 J compared to the 6% NaOH treated fibre particulate hybrid composites.
