摘要： A method for molding analysis of a plate-like intermediate base material containing resin and reinforcing material when the base material is molded, including applying a base material model having anisotropy between out-of-plane direction and an in-plane direction orthogonal to the out-of-plane direction, and calculating viscosity distribution in a cross-section direction of a molded article using each viscosity in accordance with a flow field, and the viscosity distribution indicates that under a boundary condition there is no slip flow of the base material on a wall surface of the mold, as a result of a shear field in the vicinity of the wall surface, a low viscosity layer that is more affected by an out-of-plane shear viscosity than a central portion of the base material is automatically formed in the vicinity of the wall surface, and the base material in the vicinity of the wall surface functions as a lubricating layer.
