An adequate evaluation methodology of structural reliability is indispensable for full use of light weight advantage of carbon fiber reinforced plastic (CFRP) members. The residual strain and stress after cure process are decisive for strength of CFRP. We have developed simulation system to predict initial defects of CFRP members, the finite element discretization of which is executed with mesoscopic separation of resin and fiber. The simulation runs with small time step of heat transfer analysis with heat generation from resin, degree of cure analysis, strain analysis by thermal contribution and polymerization shrinkage, and visco-elastic analysis of resin under cure progress. A numerical solution is presented to demonstrate the prediction of residual stress and strain generated in CFRP Laminates.
