“…Fundamentally, the incorporation of fiber reinforcement and polymer matrix results in composite materials that exhibit remarkable stiffness, strength, and toughness. The reinforcing fibers are typically categorized into three groups: "natural fibers" (i.e., bamboo, kenaf, sisal, jute) [14,15], "synthetic fibers" (i.e., carbon fibers, glass fibers, aramid fibers) [16] and "animal-based fibers" (i.e., wool, silk, leather fiber) [17]. The polymer matrix plays a crucial role in connecting the fibrous reinforcement from the surroundings and facilitating the appropriate alignment of the fibers.…”
