Development of CNF Reinforced Plastics Manufacturing Process

Abstract

In domestic, the development of CNF production process and CNF application are advanced, but there are still not a lot of commercial productions with CNF. In order to expand commercialization of CNF, it is important to reduce the production cost of CNF and to promote the development of technologies for expanding product applications. And reducing CO₂ emissions will realize social implementation and market expansion at early stage because of motivation for decarbonized society.
The integrated manufacturing process from CNF raw material to CNF reinforced plastics was developed through the technology of the continuous process and the high productivity method of CNF reinforced plastics with a twin-screw extruder （CNF contents 67%, 250 kg/h by φ48 mm equipment）.
These development results were conducted as a NEDO’s project from 2020 to 2022 with Shibaura Machine Co., Ltd. and National Institute of Advanced Industrial Science and Technology.
