Recent Progress in Flax Fiber-Based Functional Composites

In recent years, flax fiber as a green and renewable resources have attracted considerable attention to be used as reinforcement in composites, using various technology. This review presents a summary of recent developments of flax fiber-based functional composites toward energy, biomedical, and environment. Firstly, we analyze the design and fabrication strategies, which are used for preparation of flax-based functional composites. The most promising applications of flax fiber-based composites are discussed subsequently. It is believed that flax fiber as a functional composites will play a crucial role in the field of energy, biomedical, and environment mainly attributed to its unique properties, such as specific mechanical properties, good biocompatibility, eco-friendliness, cost-effectiveness, and amenability to various functional design and manufacturing needs.
