SURFACE COATED REINFORCED FIBER, MANUFACTURING METHOD OF THE SURFACE COATED REINFORCED FIBER, INTERMEDIATE SUBSTRATE, COMPOSITE MATERIAL AND MOLDED BODY CONTAINING THE SURFACE COATED REINFORCED FIBER AND RESIN

摘要

To effectively enhance mechanical strength of a molded body consisting of a composite material by enhancing adhesiveness of reinforced fibers and a matrix resin by a fiber reinforced resin composite material containing the reinforced fibers and the matrix.SOLUTION: A surface coated reinforced fiber is manufactured by directly coating at least a part of a surface of a reinforced fiber by a nanocellulose layer, which is a layer consisting of nanocellulose (NCe). NCe may be cellulose nanofiber (CeNF), and be modified by a functional group. The surface coated reinforced fiber can be manufactured by removing a dispersant after applying a dispersion in which NCe is dispersed in the dispersant to a surface of the reinforced fiber. The invention also relates to an intermediate substrate containing the surface coated reinforced fibers and the matrix resin, a composite material, and a molded body containing the composite material.SELECTED DRAWING: Figure 3
