Fiber reinforced composite materials can be seen everywhere in our daily life. The development speed of thermoplastic composites has gradually surpassed that of thermosetting materials because of their low density, recyclability and high production efficiency. Polylactic acid (PLA) and jute fibers are two of the most attractive research pursuits in the field of biodegradable materials nowadays. In this work, PLA films and jute nonwovens were made firstly, then biodegradable composite materials were produced combining PLA as the matrix with jute fiber as reinforcement using the film-stacking method. The mechanical properties of the prepared biodegradable materials were characterized by tensile testing and 3-point bending testing. The biodegradable composite materials have great potential applications in various fields with advantages of low cost, easy manufacture, low density and excellent mechanical properties.

纤维增强复合材料在我们的日常生活中随处可见。热塑性复合材料的低密度，可回收性和高生产效率使其发展速度逐渐超过热固性材料。聚乳酸（PLA）和黄麻纤维是当今生物可降解材料领域中最吸引人的两项研究追求。在这项工作中，首先制备了PLA薄膜和黄麻无纺布，然后使用薄膜堆叠方法将PLA用作基质，将黄麻纤维作为增强材料，生产出可生物降解的复合材料。通过拉伸试验和三点弯曲试验表征了所制备的可生物降解材料的机械性能。这种可生物降解的复合材料具有成本低廉的优点，在各个领域都有广阔的应用前景。
