High-Speed Tensile Test of CNF-Reinforced Plastic

Cellulose is the main component of plants. It is also the most abundant carbohydrate on earth and has been used as raw materials of paper and textiles since antiquity. In recent years, cellulose nanofiber (CNF) with higher functionality realized by defibrating cellulose to the nano level has attracted considerable attention. CNF has low environmental impacts, as it is a plant-derived material, and possesses a variety of desirable functions, including low linear expansion, a gas barrier property, and transparency. It is also lightweight, weighing only 1/5 as much as steel, and displays high specific strength 5 to 8 times stronger than ferrous materials. For these reasons, research aimed at developing composite materials with a combination high strength and light weight by adding CNF to thermoplastic resins is currently in progress, and application in various fields is expected. One such field is the automotive industry, where the ultimate purpose is to improve fuel efficiency by reducing auto body weight. However, considering the use conditions of automobiles, it is essential to clarify not only the static mechanical properties of materials, but also their impact properties, fatigue characteristics, and thermal characteristics. In this article, the tensile strength of CNF-reinforced plastic was evaluated at various test speeds (strain rates) by using a Shimadzu testing machine and high-speed impact testing machine. The fracture surfaces of the specimens after the tests were also observed by using an electron probe microanalyzer (EPMA).
