• Toughness of PLA/flax fiber blends was improved by epoxidized cardanol. • Full biodegradable and biobased polymer blends with lower cost was developed. • Toughening mechanism was revealed based on the mechanical properties and SEM graphs. Poly (lactic acid) (PLA)/flax fiber/cardanol (or epoxidized cardanol) blends were prepared by mould injection. Epoxidized cardanol was effective on toughening PLA/flax fiber blends. The maximum notched Izod impact strength of PLA/flax fiber/epoxidized cardanol (80/10/10) blend reached 10.42 ± 0.61 kJ/m2 i.e. two fold of PLA/flax fiber (90/10) blend (5.18 ± 0.23 kJ/m2). Also, the elongation at break of PLA/flax fiber/epoxidized cardanol (85/5/10) blend was promoted to 43.76 ± 8.58 %, which was over four fold of PLA/flax fiber (95/5) blend (9.94 ± 1.65 %). The improved interfacial compatibility caused by epoxidized cardanol was presumed to be responsible for the superior toughness. [ABSTRACT FROM AUTHOR]
