The present invention relates to a method of producing a coating liquid impregnated sheet-like reinforcing fiber bundle formed by applying a coating liquid to a sheet-like reinforcing fiber bundle that is unidirectionally arranged continuous reinforcing fibers long in one direction. The present invention provides a production method and a coating device of a coating liquid impregnated sheet-like reinforcing fiber bundle, wherein the method and device can effect continuous running without clogging of generated fuzz even at a high running speed and effect efficient impregnation of a coating liquid into the sheet-like reinforcing fiber bundle. The present invention relates to a method of producing a coating liquid impregnated sheet-like reinforcing fiber bundle, including allowing a sheet-like reinforcing fiber bundle, which is unidirectionally arranged reinforcing fibers, to pass substantially vertically downward through the inside of a coating section storing a coating liquid, whereby the method provides the sheet-like reinforcing fiber bundle with the coating liquid; wherein the coating section includes a liquid pool and a narrowed section which are in communication with each other; wherein the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the sheet-like reinforcing fiber bundle, and wherein the narrowed section has a slit-like cross-section and has a smaller cross-sectional area than the top side of the liquid pool.

A molding method for a composite sheet used for manufacturing a thermosetting resin prepreg sheet in which a thermosetting resin material is impregnated into a fiber sheet includes: bringing a resin transfer sheet in which the thermosetting resin material of a predetermined thickness is carried on one surface of a transfer sheet into contact with one surface of the fiber sheet to be stacked on the fiber sheet. The resin transfer sheet and the fiber sheet in the stacked state are subjected to a heating treatment or heating and pressurizing treatment. The resin transfer sheet and the fiber sheet in the heated and stacked state is subjected to a cooling treatment or cooling and pressurizing treatment so that the thermosetting resin material is transferred to the fiber sheet and the thermosetting resin material is made to adhere to one surface side of the fiber sheet.

A two dimensional unitary preform sheet including a substrate and a fiber bundle arranged on the substrate and attached to the substrate by a plurality of stitches of a thread, which may be a thermoplastic thread. The two dimensional unitary preform sheet is configurable into a three dimensional preform. According to embodiments, the fiber bundle includes carbon fibers, glass fibers, aramid fibers, or a combination thereof. According to embodiments, the two dimensional unitary preform sheet is cut in a pattern that is foldable into the three dimensional preform. A method for making a three dimensional preform is also provided, which includes forming a two dimensional unitary preform sheet and placing the two dimensional unitary preform in a press to bend the two dimensional unitary preform into the shape of the three dimensional preform.

An example of a method of manufacturing a component from a composite prepreg includes collecting a specimen from the composite prepreg and quantifying an amount of surface resin of the specimen by submerging the specimen in a container containing a fluid to determine a fluid pickup percentage. Responsive to a determination that the fluid pickup percentage exceeds a predefined threshold value, forming a component from the composite prepreg.

According to one implementation, a preform shaping apparatus includes at least one mold and at least one pin. The at least one mold is a mold for placing and shaping a laminated body of fiber sheets which is a material of a fiber reinforced plastic. The at least one pin prevents the fiber sheets from being misaligned by stinging the laminated body of the fiber sheets with the at least one pin. Further, according to one implementation, a preform shaping method for producing a preform includes: placing a laminated body of fiber sheets, which is a material of a fiber reinforced plastic, on at least one mold; shaping the laminated body of the fiber sheets; and preventing the fiber sheets from being misaligned by stinging the laminated body of the fiber sheets with at least one pin.
