The main purpose of this project is to develop high-rate production aircraft PMC products and quality assurance technology for next-generation CFRP aircraft structures. This project consists of five research units, (1) OoA CFRP (Airframe) Unit, (2) Low-Cost/High-Toughness Autoclave CFRP (Airframe) Unit, (3) CFRTP (Engine) Unit, (4) High-Temperature CFRP (Engine) Unit, and (5) Academic Support and Material Evaluation Unit. A strong collaboration among fiber/matrix industries, aircraft manufacturing industries, universities and national institutes is key for the success of this program.
Started in 2016

We are developing a technology replacing CFRP made from petroleum with plant biomass for a purpose of further increase of CO2 reduction effect in CFRP aircraft life cycle, and also as a countermeasure against the soaring oil price due to fossil resource depletion. It is said that the CO2 reduction effect would be 1.4 times to 5 times of the production weight at least when biomass products substitutes for petroleum-based plastics (trial calculation by Japan Organics Recycling Association). Therefore, when we use about 20 tons of carbon fiber and about 20 tons of base material resin for an aircraft (trial calculation by Japan Carbon Fiber Manufactures Association), CO2 reduction effect by replacing them from petroleum origin to bio-derived one would be ~ 200 tons / machine.
Oil plants are used as material plants for producing CFRP. Specifically, we manufacture carbon fiber monomer compounds and thermoset resin materials from byproduct compounds during producing biodiesel fuel (BDF) from vegetable oil.
As for lignocellulose, which is the main component of oil expression residue of vegetable oil, we produce thermoplastic resin by combining chemistry and biological reaction through pretreatment with normal temperature and normal pressure using ionic liquid. We manufacture CFRP from carbon fiber and thermoplastic resin obtained during the above process and evaluate its characteristic.
