Abstract
Mechanical properties and dimensional accuracy of FRP parts depend on molding process. In this study, a simulation method considering molding process to predict those of FRP parts has been developed. In this paper, some new characteristics were proposed to analyze curing process of the matrix because after cure effect and cure shrinkage would affect the deformation and residual stress in the FRP parts. The characteristics data to predict cure temperature corrected by after cure effect were acquired experimentally by evaluating the proportions of the thermal deformation of CFRP laminates molded by after cure process to those of them molded by no after cure process. And the new parameters to predict the deformation of CFRP parts caused by cure shrinkage were acquired experimentally by evaluating the cure shrinkage strains of CFRP and contribution of resin cure shrinkage to deformation of CFRP laminates.
