REINFORCED FIBER TAPE MATERIAL, AND FIBER REINFORCED RESIN MOLDED BODY BY IMMERSING AND CURING MATRIX RESIN IN THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a reinforced fiber tape material good in impregnation property of a matrix resin and excellent in handleability (especially shape stability), and a fiber reinforced rein excellent in physical properties such as impact resistance (especially interlayer toughness, CAI) with high productivity by impregnating and curing the matrix resin into the same.;SOLUTION: There are provided a reinforced fiber tape material for resin impregnation molding in which reinforced fibers constituting a reinforced fiber strand each other and/or a plurality of reinforced fiber strands each other are bound and united each other by a first porous resin material with porous shape arranged on one side, and a second porous resin material arranged on another surface, softening points of the first resin material and the second resin material are higher than curing temperature Tc of a thermosetting matrix resin impregnated and cured later, and the second resin material is a material soluble in the matrix resin at lower temperature than curing temperature Tc, and a fiber reinforced resin molded body by impregnating and curing the matrix in the same.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPIT
