Influence of Palm Kernel Shell Particle Size on the Performance of Waste Polystyrene Matrix Composites

Usman, M.^*, Ishiaku S. U., Umaru H. I, Lawal N

The valorisation of agricultural and plastic wastes provides a sustainable path for developingeco-friendly composite materials. This study investigates the influence of palm kernel shell(PKS) particle size on the physical, mechanical, and morphological properties of wastepolystyrene matrix (WPS) composites. PKS particles of 100 μm, 200 μm, and 300 ...

EVALUATION OF MECHANICAL AND PHYSICAL PROPERTIES OF BAMBOO LEAF NANO SILICA FILLED WITH RECYCLED LOW DENSITY POLYETHYLNE COMPOSITE

Magaji I. Y^*, Umaru H. I, Abdulkadir Suleiman Abdulrahman, Yakubu C.I, Pascaplina L, Hassan S, Kabiru A.B

This study investigates the influence of bamboo leaf nano-silica (BLNS) filler on the mechanical and physical properties of recycled low-density polyethylene (RLDPE). RLDPE composites were fabricated using a two- roll mill at 150°C, followed by compression moulding. A comprehensive evaluation of the composites was conducted, encompassing tensile, i...

THE EFFECT OF FILLER LOADING ON PHYSICAL AND MECHANICAL PROPERTIES OF MAIZE STRAW AND WASTE POLYPROPYLENE PARTICLE COMPOSITE

Magaji I. Y^*, Abdulkadir Suleiman Abdulrahman, Umaru H. I, Yakubu C.I, Pascaplina L, Hassan S, Kabiru A.B

This study investigates the effects of maize straw as a filler material in polypropylene composites, with a focus on understanding the influence of filler loading on the material's mechanical and physical properties. Maize straw was prepared by drying and grinding before being compounded with polypropylene using a two-roll mill. The resulting compo...
