由于聚乳酸聚合物的脆性，更实际的应用需要改性。PLA的冲击性能的改善是填料或增强剂的添加。采用竹纤维、香根草纤维和椰子纤维作为PLA复合材料的交替增强体。制备了不同增强体含量的未处理和柔性环氧树脂处理的复合材料的注射成型。天然纤维增强聚乳酸复合材料的冲击强度随纤维含量的增加而降低。竹纤维/PLA、香根草纤维/PLA和椰子纤维/PLA复合材料的冲击强度最大下降分别为23.8%、27.3%和56.2%。与未处理的复合材料相比，柔性环氧树脂表面处理改善了竹纤维/PLA和椰子纤维/PLA复合材料的冲击性能。与其他组合不同，与其他天然纤维相比，处理过的香根草纤维/PLA复合材料的冲击强度改善较小。竹纤维被证明是最有效的增强所有研究的增强。
The modification is required for more practical applications due to the brittleness of PLA polymer. The improvement of the impact properties of PLA is an addition of fillers or reinforcements. Bamboo fiber, vetiver grass fiber and coconut fiber were used as alternative reinforcements in PLA composites. Injection molded of untreated and flexible epoxy treated composites at various reinforcement content was prepared. The impact strength of natural fiber reinforced PLA composite decreased with the increased of fiber content. The maximum reduction in impact strength was 23.8, 27.3 and 56.2% for bamboo fiber/PLA, vetiver grass fiber/PLA and coconut fiber/PLA composites, respectively. The flexible epoxy surface treatment improved impact property of bamboo fiber/PLA and coconut fiber/PLA composites when compared against the untreated composites. Unlike the other combinations, treated vetiver grass fiber/PLA composite showed less improvement in impact strength when compared with other natural fibers. Bamboo fiber proved to be the most effective reinforcement among all studied reinforcements.
