Abstract 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.

Introduction The extensive use of conventional petroleum-based composite materials, together with the white plastic in the nature have awaken people’s awareness of environment protection. Hence, the natural fiber is usually combined instead of synthetic fiber in composite materials fabrication in recent years because of their superior comprehensive properties such as low cost, abundance, environmental and the excellent mechanical properties. As a kind of natural cellulose fiber, jute fiber possesses outstanding performance compared with other nature and man-made fiber as demonstrated in Table 1 (Gosline et al. 1999; Fu et al. 2015; Chandrasekar et al. 2017; Sudamrao Getme and Patel 2020). Jute fiber reinforced composites have been successfully applied in the fields of automobile interior decoration and architectural furnishing (Reddy et al. 2014). Shivamurthy et al. (2020) explored the possibility of alkali treated jute fiber reinforced cashew shell liquid mixed with epoxy resin composites. The feasibility of prepared jute composites is characterized by mechanical properties testing and quantified by tensile strength and bending strength. Basak et al. (2018) and Maharan et al.
