Recent advances in the development and application of bio-based (natural fiber and biopolymer) composites are gaining broad attention because the resulting polymer completely degrades and does not release harmful substances. In this study, natural fiber 3 D braided yarn textile PLA (Polylactic acid) bio-composites are developed by film sequencing followed by hot-press compression molding. Bio-deterioration and thermal stability of the composites are analysed for storage, machining, transportation, and in-service uses in different environmental conditions (compost and thermal). Composite samples with different fiber wt.% (0, 22, 44) are exposed to compost soil. Tensile testing is performed under different configurations to characterise the tensile properties. Prepared bio-composite specimens are evaluated for weight loss and reduction in tensile properties over soil burial time, to observe the rate of biodegradation of braided yarn textile bio-composites. Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) is employed to analyse the biodegradability of the composites. To study the thermal stability of the prepared bio-composites thermogravimetric (TG) analysis is carried out. Results showed that biodegradability, tensile properties and thermal stability of the composites are enhanced significantly with the reinforcement of 3 D braided yarn fabric.

3D编织亚麻PLA纺织复合材料的生物降解特性和热重分析

生物基(天然纤维和生物聚合物)复合材料的开发和应用的最新进展正受到广泛关注,因为所得聚合物会完全降解,并且不会释放有害物质。在这项研究中,天然纤维3D编织纱线纺织品PLA(聚乳酸)生物复合材料是通过薄膜定序,随后进行热压压缩成型而开发的。分析了复合材料的生物降解性和热稳定性,以用于在不同环境条件(堆肥和热环境)下的存储,加工,运输和使用中。将具有不同纤维重量%(0、22、44)的复合材料样品暴露在堆肥土壤中。在不同的配置下执行拉伸测试以表征拉伸性能。评价制备的生物复合材料样品的失重和土壤埋藏时间内拉伸性能的降低,以观察编织纱线纺织品生物复合材料的生物降解速率。傅里叶变换红外(FTIR)和扫描电子显微镜(SEM)用于分析复合材料的生物降解性。为了研究所制备的生物复合材料的热稳定性,进行热重分析。结果表明,随着3D编织纱织物的增强,复合材料的生物降解性,拉伸性能和热稳定性得到显着增强。傅里叶变换红外(FTIR)和扫描电子显微镜(SEM)用于分析复合材料的生物降解性。为了研究所制备的生物复合材料的热稳定性,进行热重分析。结果表明,随着3D编织纱织物的增强,复合材料的生物降解性,拉伸性能和热稳定性得到显着增强。傅里叶变换红外(FTIR)和扫描电子显微镜(SEM)用于分析复合材料的生物降解性。为了研究所制备的生物复合材料的热稳定性,进行热重分析。结果表明,随着3D编织纱织物的增强,复合材料的生物降解性,拉伸性能和热稳定性得到显着增强。
