Manufacturing apparatus and method of manufacturing a tow prepreg

A resin supply unit of a manufacturing apparatus supplies a resin to a roller surface of an impregnated roller which is capable of rotating at a constant speed. A transport mechanism brings the fiber bundle into contact with the resin on the roller surface and thereby forms a tow prepreg while the f...

Beschreibung
Zusammenfassung:	A resin supply unit of a manufacturing apparatus supplies a resin to a roller surface of an impregnated roller which is capable of rotating at a constant speed. A transport mechanism brings the fiber bundle into contact with the resin on the roller surface and thereby forms a tow prepreg while the fiber bundle is being transported. A fineness acquisition unit acquires as a fineness acquisition value a fineness, which is defined by a mass per unit length of the fiber bundle during conveyance thereof before being brought into contact with the resin. A resin supply amount control unit controls the resin supply amount based on the fineness acquisition value, in a manner so that a resin content of the tow prepreg becomes a target resin content.
