“…In recent decades, natural plant-fibers-reinforced polymer matrix composites have received more and more attention due to their low-density, low-cost, good durability, environmental friendliness, and favorable biodegradability. [1][2][3][4][5] Several natural plant fibers, including jute, hemp, flax, bamboo, kenaf, and sisal had been widely used to reinforce thermosetting polymers (eg, epoxy, unsaturated polyester, etc. ), [6][7][8][9][10][11] and thermoplastics polymers (eg, polypropylene (PP), poly(vinyl chloride), polyethylene, polylactic acid, poly(butylene succinate), etc.).…”
