Abstract: 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.

Abstract: A method of producing a prepreg is described, in which a matrix resin is applied to a reinforcing fiber sheet in which the sheet can continuously run without clogging due to generated fuzz even at a high running speed and where the reinforcing fiber sheet can be efficiently impregnated with the matrix resin. A method of producing a prepreg includes allowing a reinforcing fiber sheet to pass substantially vertically downward through the inside of a coating section storing a matrix resin to apply the matrix resin to the reinforcing fiber sheet; and then applying a resin film to a primary impregnate prepreg withdrawn from the coating section.

Abstract: A reinforcing fiber mat manufacturing apparatus according to the present invention is a reinforcing fiber mat manufacturing apparatus that includes a hitting mechanism (40) that comes into contact with a reinforcing fiber bundle to split the reinforcing fiber bundle into a plurality of pieces, and, disperses the plurality of pieces. The hitting mechanism (40) includes a rotation shaft (41), a pair of rotation plates (42) attached to portions of the rotation shaft (41) apart from each other, and a plurality of hitting pieces (43) arranged to extend in parallel to the rotation shaft (41) between the pair of rotation plates (42). The reinforcing fiber mat manufacturing apparatus according to the present invention is a simple apparatus that reliably hits a reinforcing fiber bundle to split the fiber bundle into thin bundles, and disperses the thin bundles to a wide range without causing air turbulence to manufacture a reinforcing fiber mat having a uniform fiber basis weight.

Abstract: A preform for the molding of a fiber-reinforced resin beam, the preform comprising: a reinforcing-fiber beam which has been formed from a reinforcing-fiber base made up of many reinforcing fibers and has a cross-sectional shape comprising at least one linear part and at least one curved part connected to the linear part; and a release sheet bonded and united through an adhesive resin to at least part of a surface of the reinforcing-fiber base along the lengthwise direction for the base. A process for producing a preform comprises: a step in which a continuous flat reinforcing-fiber base having a release sheet bonded and united to a surface thereof is shaped so that the cross-sectional shape of the base comes to have a curved part to thereby produce a preshaped object; and a preshaped-object uniting step in which the preshaped object is bonded and united to another preshaped object.
