Natural Fiber and Plastic Composites

A Review of Natural Fiber-Reinforced Composites for Lower-Limb Prosthetic Designs

“…The mold is then filled with resin, which is then heated to start the resin's curing process. Compression molding permits the creation of intricately formed components, and is appropriate for high-volume production [33,89,121,146].…”

“…In this technique, the fibers are pulled through a resin bath and subsequently passed through a heated die, resulting in resin curing. Pultrusion is well suited for creating components with a consistent cross-section and is commonly employed in the construction sector [89,120,121,146,147].…”

“…NFRCs have many advantages over synthetic and conventional materials [30][31][32]. Natural fibers, such as kenaf, flax, or jute, can be used to create these types of composites [29,73,[88][89][90]. Natural fiber-reinforced composites have exceptional mechanical qualities, including a low density, biodegradability, and high strength-to-weight and impactresistance ratios [29,33,34,90].…”

“…Ensuring the consistent quality and performance of NFRCs is one of the key issues regarding these materials. Natural fibers can have different qualities depending on factors such as their moisture content and the harvesting conditions [89,[91][92][93]. Nevertheless, recent studies have shown that high-quality natural fiber-reinforced composites may be fabricated to match the specifications for prosthetic designs with fiber treatment and a good composite composition [30,31,79,94,95].…”

“…Derived from diverse sources (Figure 2), such as plants, animals, and minerals [69,90,96], natural fibers have become increasingly popular in recent years owing to their cost-effectiveness, biodegradability, and renewability [30][31][32]. [29,73,[88][89][90]. Natural fiber-reinforced composites have exceptional mechanical qualities, including a low density, biodegradability, and high strength-to-weight and impactresistance ratios [29,33,34,90].…”
