采用模具注射法制备了聚乳酸/亚麻纤维/腰果酚(或环氧化腰果酚)共混物。环氧化腰果酚对聚乳酸/亚麻纤维共混物具有良好的增韧效果。聚乳酸/亚麻纤维/环氧化腰果酚(80/10/10)共混物的最大缺口冲击强度为10.42±0.61kJ/m2。两倍聚乳酸/亚麻纤维(90/10)共混(5.18±0.23)kJ/m2。聚乳酸/亚麻纤维/环氧化腰果酚(85/5/10)共混物的断裂伸长率为43.76±88.58%，是聚乳酸/亚麻纤维(95/5)共混物(9.94±91.65%)的4倍以上。环氧化腰果酚改善了界面的相容性，被认为是产生优异韧性的原因。
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/m2i.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.
