Natural fiber reinforced composites are currently used in various fields such as automobile, building construction and furniture materials considering the increasing environment pollution caused by the extensive use of plastic products. In this study, jute fiber and polylactic acid (PLA) were combined to prepare jute PLA-based biodegradable composites. PLA is one of the most attractive research pursuits among thermoplastic composites due to its excellent biodegradability and the ultimate degradation products of PLA are carbon dioxide and water, which have no pollution to the environment. Basically, the mechanical and thermal performances of the jute/PLA laminated composites were characterized and analyzed in this work. The analytical results on jute/PLA sandwiches reveal that different ply counts and stacking sequences significantly influence the mechanical properties of the composites material. The study on jute/PLA composites will provide quantitative experimental data for potential applications with advantages of lightweight, cost effective, easy manufacture, biodegradable and excellent mechanical properties.

考虑到由于塑料产品的广泛使用而导致的环境污染的增加，天然纤维增强的复合材料目前被用于各种领域，例如汽车，建筑结构和家具材料。在这项研究中，黄麻纤维和聚乳酸（PLA）结合在一起，以制备基于黄麻PLA的生物可降解复合材料。PLA具有出色的生物降解性，并且PLA的最终降解产物是二氧化碳和水，对环境无污染，因此PLA是热塑性复合材料中最吸引人的研究追求之一。基本上，在这项工作中对黄麻/ PLA层压复合材料的机械和热性能进行了表征和分析。黄麻/ PLA三明治的分析结果表明，不同的层数和堆积顺序会显着影响复合材料的机械性能。黄麻/ PLA复合材料的研究将为潜在的应用提供定量的实验数据，其具有重量轻，成本有效，易于制造，可生物降解和优异的机械性能的优点。
