摘要: Abstract In the given research paper, effects of reinforcing polylactid (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) biopolymers on mechanical performance were studied. Both PLA PHBV compounded with man-made cellulose, jute abaca fibres. The test bar specimens processed via injection moulding. Various testing methods, including tensile impact tests, used to investigate composites’ performance. Scanning electron microscopy was carried out study fibre–matrix interphasial adhesion. To determine fibre-size distribution, optical used. Finally, obtained results compared composites PP basis same fibres increased stiffness strength significantly; however, depending fibre type, different improvements parameters achieved. main enhancement realised in by cellulose SEM photographs show a largely differing fibre/matrix bonding for composites. broadest distribution can be found
