MULTI-LAYERED REINFORCED FIBER SHEET, FIBER-REINFORCED POLYMERIC FORMED PRODUCT AND METHOD FOR PRODUCING A MULTILAYERED REINFORCED FIBER SHEET

摘要

The present invention provides a reinforced fiber sheet exhibiting a stable shape and favorable bulking properties, a method for manufacturing same, and a fiber-reinforced resin molded body. The reinforced fiber sheet according to the present invention comprises a plurality of reinforced fiber bundles that are arranged in one direction, wherein first and second reinforced fiber bundle layers, in which there is no direct binding force between reinforced fiber bundles within a layer, are disposed so as to have mutually distinct fiber orientations, and are integrally formed by being fastened together using fastening elements, satisfying conditions (i) and (ii). (i) Fastening surfaces of the first and second reinforced fiber bundle layers have fastening sections that include at least one fastening element, and an average surface area S1 of 100 mm 2 . (ii) In the fastening sections, the surface area ratio of the fastening elements to the fastening section is 0.1% to 80%, inclusive.
