Document Type and Number:
Japanese Patent JP6733541
Kind Code:
B2
Abstract:
There are provided a sheet-like reinforcing fiber base material that is provided to reduce a waste in production of a fiber-reinforced resin molded product and to have a little position shift of a reinforcing fiber base material for reinforcement, as well as a preform and a fiber-reinforced resin molded product. The sheet-like reinforcing fiber base material is configured to maintain a sheet-like form by arraying and arranging reinforcing fiber bundles such that longitudinal directions thereof are one identical direction and restraining positions of adjacent reinforcing fiber bundles each other. In the sheet-like reinforcing fiber base material, the placement amount of reinforcing fibers is partly increased, such that the placement weight of reinforcing fibers per unit area is non-uniform.
