Fiber-reinforced polymer composites have been used in recent years as an alternative to the conventional materials because of their low weight, high mechanical properties, and low processing temperatures. Most polymer composites are traditionally made using reinforcing fibers such as carbon or glass fibers. However, there has been recent interest in making these reinforcing fibers from natural resources. The plant-derived cellulose nanofibers (CNF) are a material with remarkable mechanical properties at the nanoscale that are much superior to the mechanical properties of the traditional natural fibers (such as jute, hemp, kenaf, etc.) used in the natural fiber-based polymer composites. Because CNF is bio-based and biodegradable, it is an attractive “green” alternative for use as a polymer reinforcement in automotive, aerospace, and other engineering applications. However, the efforts to produce CNF-based nanocomposites, after successfully scaling-up of the remarkable nanoscale properties of CNF, have not met with much success and form an active area of research. |
