Innovative composite material development by supercomputer


Innovation of composite technology is expected for application spread.

Tohoku University and NEC Corporation are jointly accelerating the development of composite materials for next generation aircraft.

The press release can be reviewed as below;


This R&D is being conducted under the Cross-ministerial Strategic Innovation Promotion Program, a national project led by the Cabinet Office, Government of Japan, aiming to reduce the development costs, manufacturing costs, and development period of composite materials for next-generation aircraft by up to 50% when compared with conventional methods.



Supercomputer utilization for innovative composite material development

NEC supports this project by applying NEC’s vector supercomputer SX-Aurora TSUBASA to accelerate the development of composite materials, especially carbon fiber reinforced plastics (CFRPs).

The summary of SX-Aurora TSUBASA can be shown as the video.

Supercomputer is designed to calculate big data like;

  • reflecting real-time results and providing optimal information in daily shopping
  • machine learning for process optimization
  • simulate whether forecast including the track of typhoon/ hurricane


Combination of supercomputer and simulation in Tohoku university

In this project, supercomputer is utilized for composite material development.

The computer is trying to give the solution for improvement of efficiency to get material properties which meet design requirement.


Tohoku university is supplying mechanical analysis technology especially focusing on fuselage.


Material properties via molecular scales are input to supercomputer, and then it simulates stress or vibration response in aircraft wing and fuselage model.

This input and analysis process repeat for material selection and design via high speed and multiple scales.



This kind of collaboration would be normal development style in near future.
