Abstract: Provided is a method for manufacturing a fiber reinforced resin molded article capable of effectively reducing the occurrence of a preform with poor resin impregnation, and such a manufacturing device thereof. After it is detected that a predetermined amount (the same amount) of resin has been individually poured into a plurality of cavities provided in a mold, the fiber layers of preforms are impregnated (compressively filled) with resin. Pressure sensors for detecting a resin injection amount are used. When closing runners, a small gap is formed in the runners.

Abstract: Provided is a method for manufacturing a fiber reinforced resin molded article capable of preventing oxidation and degradation of a liner making up a preform at a high temperature, and such a manufacturing device thereof. Prior to pouring resin into a mold, the method fills inert gas (nitrogen gas, for example) into the mold. After filling inert gas (nitrogen gas, for example) into the mold, the method closes an upper mold (second mold) placed with a gap (second gap) with a preform (i.e., brings it closer to the preform).

Abstract: In a tank manufacturing method using a helical winding device that winds fiber bundles around a mandrel, the device includes: a first guide ring having an opening to pass the mandrel therethrough and placed around the mandrel with an axial center of the mandrel being taken as a center; and a plurality of first guide portions placed in the first guide ring along a circumferential direction around the axial center and configured to supply first fiber bundles to the mandrel. The method includes: moving the mandrel relative to the first guide ring along an axial center direction along the axial center such that the mandrel passes through the opening; and winding the fiber bundles around the mandrel while relatively moving the mandrel in the moving, by the first guide portions supplying the first fiber bundles to the mandrel with the first guide portions swinging in the circumferential direction.

Abstract: Provided is a method for manufacturing a tank and a manufacturing device thereof that can achieve resin impregnation within a short time. The method wraps fibers in an overlapping manner in a radial direction around an outer surface of a liner such that a first fiber layer (braiding layer) on an outer surface of a dome portion is less dense than a second fiber layer (helical layer) on an outer surface of a straight body portion and such that a portion of a lamina of the first fiber layer, which is less dense, is interposed continuously from the first fiber layer partially between laminae of the second fiber layer, and then impregnates the fiber layer including the first fiber layer and the second fiber layer with a resin.

Abstract: Provided is a method for manufacturing a fiber reinforced resin molded article capable of effectively increasing the strength of a fiber reinforced resin molded article, such as a high-pressure tank, and such a manufacturing device thereof. With use of a cutting core that is heated to a higher temperature than a mold, the curing of a portion of resin (thermosetting resin) to be cut in a runner is facilitated, and the portion of the resin to be cut in the runner is cut by the cutting core. The heating temperature of the cutting core is higher than the temperature of the mold and lower than the heating temperature in an aftercure step performed after removing the high-pressure tank from the mold.
