Due to its promising physical and mechanical characteristics, cellulose fiber has currently gained highly global attention in material science field, particularly in exploring and applying nanocrystalline cellulose fibers for industrial use. Efforts should be made in the future development of new nanocrystalline cellulose fiber-based products, which may lead to the development of “green materials” and “green industry”. Taiwan is rich in bamboo resources, which provides abundant raw materials for producing bamboo-based nanocrystalline cellulose fibers. The development of bamboo-based nanocrystalline cellulose fiber materials can not only significantly increase their added value but also benefit the environment by substituting other high energy-consuming and carbon emission man-made materials. However, the possibility of nanocrystalline cellulose fiber application have not yet been fully exploited; more should be done to fulfill the gap. In particular, applying nanocrystalline cellulose fibers for developing composite materials to enhance their properties. In this study, locally-available bamboo resources will be used to produce nanocrystalline cellulose fibers, and physical and mechanical properties will be tested and evaluated; furthermore, proper reinforcing modification means will be probed in order to create nanofibers with superior performance; and then biofiber-reinforced composite materials will be developed. Consequently, the added value of bamboo will lead to new applications. The major tasks consists of three stages: 1. Development and evaluation of the bamboo-based nanocrystalline cellulose fiber. 2. Modification of the bamboo-based nanocrystalline cellulose fiber. 3. Development of bamboo-based nanocrystalline cellulose fiber reinforced composite materials竹材奈米微晶纖維素奈米纖維生物複合材料bamboonanocrystalline cellulosenanofiberbio-composite material
