Title:
不織布、不織布の製造方法および繊維強化プラスチック成形体
Document Type and Number:
Japanese Patent JP6493147
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a nonwoven fabric that can, when used as a forming material for a fiber-reinforced plastic (FRP) molded article, produce an FRP molded article having a high flexural modulus; a production method for said nonwoven fabric; and an FRP molded article produced by heat pressure forming said nonwoven fabric.SOLUTION: Provided is a nonwoven fabric comprising a flat-shape glass fiber having a cross section perpendicular to the longitudinal direction of flat shape and having a ratio of the major axis to minor axis of said cross section (major axis/minor axis) of 1.5 to 8, and a thermoplastic resin fiber; said nonwoven fabric preferably is a wet type nonwoven fabric, and can be produced by a process comprising a papermaking step for papermaking a fluid dispersion containing said flat shape glass fibers and said thermoplastic resin fibers; and the FRP formed article produced by heat pressure forming the obtained nonwoven fabric, has an excellent flexural modulus.SELECTED DRAWING: None
