The Research Institute for Sustainable Humanosphere (RISH) at Kyoto University and Kyoto Municipal Institute are collaborating with Oji Holdings Corp., Nippon Paper Industries Co., Ltd. and Seiko PMC Corp. under the NEDO (New Energy and Industrial Technology Development Organization) project entitled “Development of the technology for the continuous production process of ligno cellulose nanofibers reinforced plastics and their applications for the structural members”. A chemically modified dry-pulp with an improved heat resistance and will be easy to fibrillate but will not be chopped under melt compounding is developed. An integrated production process that simultaneously nanofibrillates the chemically modified dry-pulp and uniformly disperses the CNF in the resins is established. Based on this continuous production process, a test plant with a production capacity of one ton/year of thermoplastic resins with 10wt% CNF starting from wood chips was constructed at RISH. The modified CNF, at 10wt% load as a filler, increases the Young’s modulus and bending strength of PA6, PA12, PLA, POM, PBT, HDPE and PP by 1.5-2.5 times. One of our potential goals is to produce automobile exterior components and home appliance components.
