摘要：

Natural fiber-reinforced polylactic acid (PLA) composites possess renewability, good mechanical properties, and biodegradability. To enhance the mechanical properties of natural fiber-reinforced composites, the flax/PLA braided yarns were woven into three-dimensional orthogonal fabrics with an integrated structure. After the fabrics was hot-pressed, three-dimensional flax/PLA composites with the flax/PLA mass ratios of 50/50 and 25/75 were formed. The results showed that the 50/50 ratio exhibited the higher tensile strength (70.20 MPa) and flexural strength (172.99 MPa), respectively. Thermal analysis indicated its enhanced thermal stability, with the main degradation regions at 354.3 degrees C and 394.7 degrees C. In addition, FTIR spectroscopy showed that the flax/PLA composites exhibited a glass transition temperature of 83.88 degrees C and a melting temperature of 172.89 degrees C. Compared to recent studies, the newly developed three-dimensional orthogonal flax/PLA composites demonstrated superior performance, indicating their potential applications in the field of biodegradable composites, particularly in high-load-bearing applications.
