Materials Integration

Domain B
Applications of the Inverse Design MI to Actual Structural Materials(CFRP)


The development of technologies related to the improvement of property and productivity of CFRP, which are becoming widely used as materials for lightweight structure, by integrated materials development system. This will enable us to lead the world in the development of transport equipment such as aircraft.

Cooperation with Domain A(A3)

We will develop inverse design MI system in domain A, and by applying it to advanced structural materials and processes in domain B the effectiveness of inverse design MI system is made known to the industry and leads to social implementation.

B1 Add value with Multi-Functional CFRP

We will develop CFRP with more then one functional domain by blending functional particles or polymers into prepregs in order to obtain required functionality for new-generation aircrafts and vehicles, such as mechanical properties as well as flammability, thermal conductivity and damping properties. To fulfil this, we will obtain data set of basic mechanical properties and functionality of CFRP structure, prepreg and matrix formulation, and then will establish databases for mechanical / functional properties and a methodology of materials by MI system.

B2 AI-assisted CFRP Design / Manufacturing Automation

The automated CFRP layered machines have been widely deployed in the latest aircraft production, and thus the international competitiveness is heavily dependent on each country's capital investment capability. We will improve Japanese aerospace industries competitiveness by innovative design, arrangement and products which fully utilize domestic materials industries' competitiveness and advanced technologies, such as MI system for challenged CFRP auto-layered products.

B3 Improvement of CFRP design freedom in 3D with thin ply

We will develop an optimum design technology for high degree of freedom thin-ply CFRP which is manufactured by spreading carbon fiber bundle widely and enable it to stack up on 3D complex shapes eliminating gaps or overlapping between CFRP tapes. This is achieved by introducing a mechanism which has can control width or thickness of towing CFRP tape during a lay-up. Applying multi scale modeling techniques, we will induce true performance of CFRP by model based design optimization. This will lead to further reduction in weight and cost and improvement in manufacturing technology. As a result, this technology will improve industrial competitiveness in Japan, including not only aviation but automobiles and other industries.
