The use of natural fibers in composite plastics is gaining popularity in many areas, and particularly the automotive industry. The use of natural fibers in polymers can provide many advantages over other filler technologies, and areas of application appear limitless. The automotive industry is currently shifting to a green outlook, as consumers are looking for environmentally friendly vehicles. Natural fibers are a renewable natural resource, and are biodegradable, which is an important characteristic for components that must be disposed of at the end of their useful life. They are recyclable and can be easily converted into thermal energy through combustion, without leaving residue. Among the natural fibers with potential application as reinforcement for polymers, curaua fiber is one that recently received special attention from researchers. Curaua is a plant from the Bromeliad family, cultivated in the Brazilian Amazon region. The fiber is extracted from its leaves, providing a high mechanical strength over traditional fibers like sisal, jute and flax. We have developed thermoplastic composites using either curaua fiber or wood flour. These materials provided a lighter weight product, with good physical properties and unique surface aesthetics. This paper reviews the properties of these bio composites in comparison with glass and mineral filled products. The products were tested in some automotive applications and the results will be discussed.
