ABSTRACT

This paper reports the mechanical properties of PLA composites incorporated with tamarind and date seed Micro fillers. The composites were manufactured through compression molding technique. The tensile results showed that the seed filler reinforcement has significantly improved the tensile strength of PLA matrix. The particulate reinforcements of both tamarind and palm almost doubled the flexural and impact strength of PLA matrix. Moreover, the date seed powder incorporated composites showed 34.68% improvement in micro hardness but the tamarind seed powder composite showed only marginal improvement (9.82%) when compared with neat PLA. Furthermore, the outcomes revealed that the wt.% of fillers play a noteworthy role in deciding the properties of the PLA composites.

摘要

本文报道了与罗望子和枣籽微填料结合的 PLA 复合材料的机械性能。复合材料是通过压缩成型技术制造的。拉伸结果表明，种子填料增强显着提高了PLA基体的拉伸强度。罗望子和棕榈的颗粒增强材料几乎使 PLA 基体的弯曲和冲击强度增加了一倍。此外，与纯 PLA 相比，掺入枣籽粉的复合材料的显微硬度提高了 34.68%，而罗望子籽粉复合材料的显微硬度仅提高了 9.82%。此外，结果表明，填料的重量百分比在决定 PLA 复合材料的性能方面起着重要作用。
