Abstract: 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.

Abstract: A gate valve is configured to have a first fluid flow path. In a state where a gate valve pin is at a first pin position, a front end section on an injection hole side of the gate valve pin closes an injection hole. In a state where the gate valve pin is at a second pin position that is more distant from the injection hole than the first pin position, a front end section opens the injection hole to make communication between the first fluid flow path and the injection hole and thereby form a resin supply line. In a state where a sleeve is at a first sleeve position and the gate valve pin is at the first pin position, a second fluid flow path is formed in the gate valve to connect an injection hole-side end of the first fluid flow path to outside of the gate valve and is made to communicate with the first fluid flow path and thereby form a cleaning line.

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apply the matrix resin to the reinforcing fiber sheet; and then applying a resin film to a primary impregnate prepreg withdrawn from the coating section.
