摘要： A method is described for producing a prepreg formed by applying a matrix resin to a reinforcing fiber sheet, wherein the method can effect continuous running without clogging due to generated fuzz even at a high running speed and effect efficient impregnation of the reinforcing fiber sheet with a 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 obtain a matrix resin-impregnated reinforcing fiber sheet in which the matrix resin is applied to the reinforcing fiber sheet and at least heating the matrix resin-impregnated reinforcing fiber sheet, 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 reinforcing fiber sheet.

摘要： A process for producing a reinforcing-fiber strip substrate having a circular-arc part includes contacting one surface of a strip-shaped, unidirectional reinforcing-fiber substrate formed by arranging a plurality of reinforcing-fiber strands in one direction in parallel with each other with a flexible member; deforming the unidirectional reinforcing-fiber substrate into a circular-arc shape by deforming at least a part of the flexible member into a circular-arc shape in a direction extending along its contact surface with the unidirectional reinforcing-fiber substrate; and thereafter, separating the flexible member from the unidirectional reinforcing-fiber substrate having been deformed.

摘要： A partially separated fiber bundle includes separation-processed sections, each divided into a plurality of bundles of at least three bundles, and not-separation-processed sections, that are alternately formed along the lengthwise direction of a fiber bundle that comprises a plurality of single fibers. The partially separated fiber bundle is characterized in that, at any width-direction cross-section taken along the lengthwise direction thereof, a rate of single fibers contained in a region at which adjacent divided fiber bundles are joined by a not-separation-processed part is 67% or less relative to the total single fibers in the width-direction cross-section.
