Abstract: A high pressure tank production apparatus includes a feeder for feeding reinforced fibers wound around a resin liner and a near infrared ray radiation unit inserted into the resin liner to radiate near infrared rays. The reinforced fibers wound around the resin liner absorb near infrared rays radiated from the radiate near infrared ray radiation unit by a near infrared absorber contained in the reinforced fibers. As a result, an outer layer made of fiber reinforced resin is formed to cover the resin liner.

Abstract: 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.

Abstract: A mandrel structure for use in manufacturing a fiber reinforced resin vessel by a filament winding process, includes: a shaft having a pair of axial ends configured to be supported by a drive unit; a mandrel having the shaft passed therethrough; and a pair of fittings having the shaft passed therethrough and projecting axially from respective axial ends of the mandrel. The mandrel is formed as a hollow shell made of a water-soluble material, and includes a pair of shaft holes receiving the shaft therein, and a receiving recess formed in a part of the mandrel surrounding each shaft hole and configured to engage the corresponding fitting in a rotationally fast manner.
