Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, a gas container with high protection includes a container body 1, the container body 1 includes a container body 11, the container body 11 includes a liner 10 and a reinforcing layer 70, and the liner 10 has an inner space for containing high-pressure gas. The liner 10 of the present embodiment is made of polyamide resin. In this embodiment, the liner 10 is made of nylon.

In the present embodiment, the liner 10 is formed by joining a plurality of members. Specifically, the liner 10 includes a liner member. The liner members are arranged in this order in the direction of the axis O. The liner member and the liner member may be joined by, for example, methods such as infrared welding, laser welding, hot plate welding, vibration welding, or ultrasonic welding. The liner 10 may be composed of a plurality of members other than three members, and may be formed by a method other than bonding a plurality of members, for example, forming the entire liner 10 as a single member. The cap is disposed in the top of the dome of the liner 10. The cap is bonded to the liner member or the liner member by, for example, insert molding.

The reinforcing layer 70 is formed to cover the outer surface of the liner 10. The reinforcement layer 70 reinforces the liner 10 to improve the strength of the can body (specifically, the strength of the can body that mainly opposes the pressure inside the can). The reinforcement layer 70 includes a CFRP layer (carbon fiber reinforced composite) 74, a gas diffusion layer 73, a GFRP layer (glass fiber reinforced plastic layer) 72, and a resin layer 71. The reinforcing layer 70 of the present embodiment has a gas diffusion layer 73 between a CFRP layer 74 and a GFRP layer 72. The enhancement layer 70 will be described in more detail.

Fig. 5 is a partially enlarged schematic cross-section of the outer wall of the can body. The reinforcing layer 70 is formed by stacking a CFRP layer 74, a gas diffusion layer 73, a GFRP layer 72, and a resin layer 71 in this order from the liner 10 side toward the outer peripheral side of the can body. The CFRP layer 74 and the GFRP layer 72 are layers made of Fiber Reinforced Plastic (FRP) composed of fibers wound on the liner 10 and a resin for impregnating the fibers. Specifically, the CFRP layer 74 and the GFRP layer 72 are layers formed by winding long fibers impregnated with resin on the liner 10 by filament winding (hereinafter referred to as "FW process") and then curing the resin. Although the reinforcing layer 70 has fine cracks and the like.

The CFRP layer 74 is a layer containing a carbon fiber reinforced Composite (CFRP). The function of the reinforcement layer 70 to ensure that the can body has sufficient strength (strength against the pressure inside the can) is mainly performed by the CFRP layer 74. The CFRP layer 74 of the present embodiment includes a hoop layer and a spiral layer as layers formed by winding carbon fibers impregnated with resin around the liner 10. The hoop layer is a layer formed by hoop-winding carbon fibers, and the spiral layer is a layer formed by spiral-winding carbon fibers. "hoop winding" is a winding method in which fibers are wound in a direction substantially perpendicular to the axis O and used to cover the outer periphery of the cylindrical portion of the liner 10. "spiral winding" is a winding method in which fibers are wound at an angle more inclined with respect to the direction of the axis O than in hoop winding, and is used to cover the outer periphery of the dome portion in addition to the outer periphery of the cylindrical portion of the liner 10. The number of hoop and spiral layers forming the CFRP layer 74 and the stacking order of the hoop and spiral layers may be changed as needed. The CFRP layer 74 is formed to cover the entire surface of the liner 10. The CFRP layer 74 is also referred to as a "reinforcement layer".

The GFRP layer 72 is a layer containing Glass Fiber Reinforced Plastic (GFRP). The primary function of the GFRP layer 72 is to protect the interior of the can body from physical or chemical stimuli applied to the surface of the can body from the outside. That is, the GFRP layer 72 inhibits lower layers, such as the CFRP layer 74, from physical damage and inhibits any chemicals or the like from entering the reinforcement layer 70. Like the CFRP layer 74, the GFRP layer 72 may be formed by stacking a desired number of hoop and spiral layers in a desired order. The hoop layer is a layer formed by hoop winding a glass fiber impregnated with a resin, and the spiral layer is a layer formed by spiral winding a glass fiber impregnated with a resin. In the present embodiment, the outermost layer of the GFRP layer 72 is a hoop layer, so that sufficient tension is easily applied when the glass fiber is wound around the liner 10, and the surface of the GFRP layer 72 becomes smooth. The GFRP layer 72 is formed to cover the entire surface of the liner 10. The GFRP layer 72 is also referred to as a "protective layer".

Examples of the resin contained in each of the layers forming the CFRP layer 74 and the GFRP layer 72 include thermosetting resins such as epoxy resins and thermoplastic resins such as polyester resins and polyamide resins. The resin contained in the CFRP layer 74 is also referred to as a first resin, and the resin contained in the GFRP layer 72 is also referred to as a second resin. In the present embodiment, an epoxy resin is used as the first resin and the second resin. The first resin and the second resin may be the same kind or different kinds. When the first resin and the second resin are of the same kind, the properties of the resins may be changed by adding a curing accelerator or a reinforcing agent, or by changing the kind or amount of the curing accelerator or the reinforcing agent when the curing accelerator or the reinforcing agent is added.

The gas diffusion layer 73 has a higher gas permeability than the CFRP layer 74 and the GFRP layer 72. Particularly in the present embodiment, the gas diffusion layer 73 has a higher gas diffusion speed in a direction parallel to the surface of the liner 10 (hereinafter also referred to as a planar direction) than the CFRP layer 74 and the GFRP layer 72. The gas diffusion rate of the gas diffusion layer 73 in the planar direction is 100 pa/sec or more. In the gas diffusion layer 73, the gas also diffuses in the thickness direction of the gas diffusion layer 73. However, in the present embodiment, the gas diffusion speed in the planar direction is used as an index indicating the degree of gas diffusion in the planar direction between the CFRP layer 74 and the GFRP layer 72. The gas diffusion rate of each of the layers forming the reinforcing layer 70 and the method for measuring the gas diffusion rate will be described in detail later.

For FRP layers, such as the CFRP layer 74 and the GFRP layer 72, the higher their gas permeability, the lower their strength as FRP layers tends to be, and the easier various substances including gas pass through them. Therefore, as described above, a layer whose gas diffusion speed in the planar direction is 100 pa/sec or more is not generally used as the CFRP layer 74 (the CFRP layer 74 mainly ensures the strength of the can body) and the GFRP layer 72 (the GFRP layer 72 is made denser than the CFRP layer 74 in order to protect the CFRP layer 74).

In the present embodiment, the gas diffusion layer 73 is formed to cover the entire surface of the liner 10. The gas diffusion layer 73 of the present embodiment is formed using a nonwoven fabric. Examples of the material forming the nonwoven fabric include thermoplastic resins such as polyester, polyethylene, polypropylene, and nylon, thermosetting resins such as polyurethane and polyimide, and glass. The material forming the nonwoven fabric may be any material as long as it has heat resistance, chemical resistance and strength sufficient as a constituent material of the reinforcing layer 70 and is stable in an environment where it is placed in the can body as the gas diffusion layer 73. The gas diffusion layer 73 is also referred to as an "intermediate layer".

The resin layer 71 is made of the same kind of resin as the second resin forming the GFRP layer 72. As described below, when the second resin forming the GFRP layer 72 is cured during the manufacture of the can body, the resin layer 71 is formed when the melted or softened second resin seeps out to the surface of the GFRP layer 72. Like the GFRP layer 72, the main function of the resin layer 71 is to protect the interior of the high-pressure gas tank 100 from physical or chemical stimuli applied to the tank body surface from the outside.
