Flexural & Impact Properties of PLA/Kenaf Fibers Bio-Composites

Siti Norasmah Surip, Wan Nor Raihan Wan Jaafar, Noor Najmi Bonnia

Abstract

Polylactic acid (PLA) reinforced kenaf fibres composites were fabricated using melt compounding and compression moulding. Kenaf bast and core fibres had undergone chemi-mechanical treatment before use. The mechanical properties of kenaf bast composites (KBC) and kenaf core composites (KCC) were studied by performing flexural and impact testing. KBC and KCC treated with 1.0M acid treatment at 60 rpm speed shows highest flexural and impact properties. The fibre surface treatment had an efficient effect on the flexural strength at 1.0M concentration, with improvement of approximately 27% of strength.
