▎ 摘　　要

The essence of the present research is based on reinforcement mechanism of hibiscus cannabinus fiber (KF) and graphene nanoplatelets (GNP) on mechanical and thermal properties of hybrid hibiscus cannabinus fiber/polypropylene (PKMG 1-5 phr) nano-biocomposites. TGA results revealed inclusion of KF and GNP enhanced charring and thermal stability of the bio-nanocomposites. DSC analysis revealed improved melting and crystallization temperatures of the materials. Flexural modulus significantly increased on inclusion of 20wt.% kenaf fiber and 5 phr GNP. XRD studies confirmed KF and GNP induced nucleation of -crystals of PP which improved toughness and impact properties of the nano-biocomposites especially at 3 phr.
