Our research contributes design and fabrication technology for composite materials, especially for carbon fiber reinforced polymeric composite (CFRP). Versatile multi-scale simulations are performed in the Koyanagi Laboratory, including multi-time scale simulation (time hominization analysis). Density functional theory (DFT), Molecular orbital (MO), Molecular dynamics (MD), Smoothed particle hydrodynamics (SPH), Computational fluid dynamics (CFD), and Finite element method (FEM) are employed to simulate various phenomena of CFRP. FEM is our major simulation method. Corresponding experiments are carried out to verify the simulated results are true. Key point of our research is considering how nano-scale phenomena and macro-scale phenomena are linked properly. All the research are being implemented with some contracts.
