METHOD FOR PRODUCING PREFORM AND METHOD FOR PRODUCING FIBER-REINFORCED PLASTIC MOLDING

摘要

A method for producing a preform for manufacture of a fiber-reinforced plastic molding. The method includes: fixing a resin-equipped film rolled out from a roll state including a release film and a fixing resin and containing a partially-cured thermosetting resin, to a surface of the dry fiber fabric rolled out from a roll with the fixing resin interposed therebetween, thereby obtaining a first dry fiber fabric; separately fixing the resin-equipped film to a surface of the dry fiber fabric rolled out from a roll with the fixing resin interposed therebetween, and detaching the release film, thereby obtaining one or more second dry fiber fabrics; and laminating the second dry fiber fabrics on a surface of the first dry fiber fabric with the fixing resin of the second dry fiber fabrics interposed therebetween.

1. A method for producing a preform for manufacture of a fiber-reinforced plastic molding including a dry fiber fabric and a resin-equipped film,
said resin-equipped film including a release film and a fixing resin fixed to one side of the release film and containing a partially-cured thermosetting resin having tackiness at a room temperature, the method comprising: a first step of fixing said resin-equipped film rolled out from a roll state to a surface of said dry fiber fabric rolled out from a roll state with said fixing resin interposed therebetween, thereby obtaining a first dry fiber fabric having the release film and the fixing resin; a second step of separately fixing said resin-equipped film rolled out from a roll state to a surface of said dry fiber fabric rolled out from a roll state with said fixing resin interposed therebetween, and detaching said release film from the resin-equipped film attached by pressure to said dry fiber fabric, thereby obtaining one or more second dry fiber fabrics having the fixing resin; and a step of laminating said second dry fiber fabrics on a surface of said first dry fiber fabric where the fixing resin is not fixed with the fixing resin of said second dry fiber fabrics interposed therebetween.
