Abstract: A resin impregnation detection device configured to detect resin impregnation in a resin impregnation process for a coil insulation layer. The resin impregnation detection device can be inserted in a narrow portion, is capable of detecting impregnation with a liquid resin, and does not leave metal foreign materials other than an optical fiber in a product even after the resin impregnation. The resin impregnation detection device includes an optical fiber including an FBG sensor, and a coating resin, which coats the FBG sensor. The coating resin includes a resin to be softened by contact with a detection target resin. The FBG sensor is applied with a compressive strain caused by cure shrinkage of the coating resin or heat shrinkage thereof from a curing temperature to a normal temperature.

Abstract: 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.

Abstract: A cover for an air conditioning device for a railway vehicle is a cover for an air conditioning device for a vehicle, which covers an air-conditioner main body. The cover includes a core made of a foamed material having heat insulating property, and a surface member made of a fiber reinforced plastic, which covers entire surfaces of the core. The core is deformed into a curved shape by elastic deformation.

Abstract: Provided is an advanced grid structure manufactured by a lamination step of laminating a first tape prepreg group, a second tape prepreg group, and a third tape prepreg group repeatedly in the stated order on a forming die, in which grooves (2, 3, 4) in a lattice shape are formed in three directions, so as to provide crossing regions (7, 8, 9) in which two tape prepreg groups overlap each other, and a heating forming step of forming a laminate by heating under pressure.
