Document Type and Number:
WIPO Patent Application WO/2016/147646
Kind Code:
A1
Abstract:
Provided are: a sheet-shaped reinforced fiber substrate that produces a less waste in manufacturing a fiber reinforced plastic molded article and reduces a positional deviation of a reinforced fiber substrate for reinforcement; a preform; and a fiber reinforced plastic molded article. The sheet-shaped reinforced fiber substrate comprises bundles of reinforced fibers aligned with longitudinal directions thereof set in one direction, the positions of the adjacent bundles of reinforced fibers being constrained to each other to keep a sheet-shaped form. The sheet-shaped reinforced fiber substrate is characterized in that, in the sheet-shaped reinforced fiber substrate, a distribution amount of the reinforced fibers is partially increased and a weight of the distributed reinforced fibers per unit area is nonuniform.
