摘要

本研究制作了由聚乳酸（PLA）和决明子（CA）组成的混合复合材料，并对其机械性能进行了评估，以评估生物填料在生物聚合物（PLA）基体中的添加量对其性能的影响。为了制作复合材料试样，在聚乳酸基体中按体积比 10%、20%、30%、40% 和 50%的比例添加了 CA 生物填料。根据美国材料与试验协会（ASTM）的规范，我们进行了实验，以确定由聚乳酸和 CA 组成的混合生物基质如何影响复合材料的机械特性。测试结果表明，在聚乳酸中添加 30% 的 CA 可提高材料的机械、动态力学分析和热重特性。性能更佳的复合材料被考虑用于进一步制造阴道镜夹具，该部件采用添加制造方法制造。

Mechanical Properties, DMA and Structural Analysis of Cassia Auriculata/PLA Blended Hybrid bio Matrix Composite

In this study, hybrid composite material composed of Poly Lactic Acid (PLA) and Cassia Auriculata (CA) were fabricated and the mechanical properties were evaluated to assess the impact of bio filler loading in the bio polymer (PLA) matrix. In order to fabricate the composite specimens, the CA bio filler was added to the PLA matrix in proportions of 10%, 20%, 30%, 40% and 50% by volume. In line with ASTM specifications, experiments were conducted to establish how the hybrid bio matrix, which was composed of both PLA and CA influenced the composite s mechanical characteristics. The test results indicated that adding 30 percent CA to PLA enhanced the material s mechanical, dynamic mechanical analysis, thermogravimetric properties. The composite composition with better properties was considered for further fabrication of a colposcopy fixture, the component was fabricated using additive manufacturing methodology.
