A three-dimensional fiber-reinforced composite includes a laminate having a plurality of fiber bundle layers that are layered in a lamination direction and include first and second outermost layers, a matrix resin; and a binding yarn. The binding yarn has first and second traverse yarn sections, and a surface-layer yarn section. The surface layer yarn section has bifurcated sections extending in opposite directions from the first and second traverse yarn sections on the surface of the second outermost layer. An additive and the matrix resin are arranged in a space enclosed by the bifurcated sections and the fiber bundles of the second outermost layer adjacent to the bifurcated sections, and also in a space between each of the first and second traverse yarn sections and fiber bundles adjacent thereto, and in a space between the first and second traverse yarn sections.

A first process in which a fiber reinforced base is placed in a cavity of a molding die and then resin is injected into the cavity of the molding die in a state where the molding die is opened by a sum of a distance Xand a distance at the time of completion of molding; a second process in which the molding die is closed to a state where the molding die is opened by a sum of a distance Xand the distance at the time of completion of molding while resin in the cavity is being drained; and a third process in which the drain of the resin from the cavity is stopped and then the molding die is closed to the distance at the time of completion of molding while a die clamping pressure is maintained at a predetermined value to cure the resin, are carried out sequentially.

A gas storage tank for storing a gas, the tank has an opening formed on at least one of two ends; a filling unit that is housed in the tank; and a support member that is arranged between the tank and the filling unit and holds the filling unit in the tank to connect a whole gap formed between the tank and the filling unit with the opening.

An energy absorber is crushed upon receiving compressive load, thereby absorbing energy. The energy absorber has a first end and a second end with respect to a direction of the compressive load. The energy absorber is formed of fiber-reinforced resin. The fiber-reinforced resin includes a stack of fiber layers having a compression direction fiber layer. The compression direction fiber layer includes fiber bundles of filament fibers. The fiber bundles are arranged such that the extending direction of the fiber bundles has a component of the direction of the compressive load. The density of the fiber bundles is gradually increased from the first end to the second end. Therefore, compressive load required for crushing is prevented from increasing at an early stage of crushing.

The technique of the invention manufactures a gas storage tank, which includes a gas absorbent/adsorbent and is capable of storing a high-pressure gas. The manufacturing process of a hydrogen storage tank first assembles a heat exchanger unit and packs the particles of hydrogen storage alloy into the heat exchanger unit. The manufacturing process then blocks hydrogen storage alloy filling holes used for packing the hydrogen storage alloy in the heat exchanger unit and attaches a detachable cover member to a hydrogen inlet. The manufacturing process subsequently locates the heat exchange unit filled with the hydrogen storage alloy in a cylindrical tank and narrows both ends of the tank to form joint openings. The manufacturing process then heat-treating the tank under water cooling and detaches the cover member. The manufacturing process attaches joint assemblies to the joint openings and forms a reinforcement layer around the outer circumference of the tank to complete the hydrogen storage tank.

A control unitacquires acceleration &#x3b1; sensed by an acceleration sensorand if the control unitdetermines that acceleration &#x3b1; does not equal zero, the control unitagain acquires acceleration &#x3b1;. In the event that the control unitdecides that acceleration &#x3b1; equals zero, the control unitacquires the weight M sensed by the weight sensorThe control unitcontinues sampling of weight M until a predetermined sampling period has elapsed. Once the sampling period has elapsed, the control unitcalculates the average of weight M obtained through sampling, and uses the calculated average and a map to determine hydrogen amount.

A high pressure tank has a cylindrical liner and a fiber reinforced plastic layer which covers the outer surface of the liner. At least one end of the liner is separable. The liner includes a cylindrical liner body and a lid. An O-ring is located between the contact surfaces of the liner body and the lid in the circumferential direction. Each contact surface has a seal surface which contacts the O-ring. One of the liner body and the lid has a deformable portion which deforms toward the seal surfaces. The structure can securely seal the separated portions of the liner when the high pressure tank is in a high pressure state.
