ABSTRACT
Fiber-reinforced composites are strong, stiff, and lightweight materials. They are widely used in aerospace, transportation, and construction industries. The most commonly used reinforcement bers for composites are glass, carbon, and aramid bers. They all have the advantages of high strength, high stiffness, and light weight; however, they are all synthetic bers, which are not renewable and have the problem of disposal at the end of their lifetimes.
