Abstract: Method for producing a composite molded body according to the present disclosure, to form a first and second composite molded bodies by molding the first and second composite materials, respectively. The first and second composite molded bodies comprise joint portions that can be joined to one another. The joint portions are joined together to form a composite material joint body. The first and second composite materials comprise to-be-joined portions corresponding to the joint portions of the first and second composite molded bodies, respectively. In the space sandwiched between the first and second composite materials disposed in the mold, a mandrel, a step of disposing a pressing portion, a step of pressing the pressing portion presses the mandrel against the to-be-joined portion of the second composite material.

Abstract: A method for producing a composite material joint body includes steps of: bonding a plurality of composite materials, forming a hollow body including at least a first cell and a second cell adjacent to the first cell, and adjusting a pressure so that a first pressure in the first cell is greater than a second pressure in the second cell. In the step of forming the hollow body, the first cell includes an expansion member pressurizing a first inner surface facing the first cell of a first cell member, and the second cell includes a gas pressurizing a second inner surface facing the second cell of a second cell member, and in the step of adjusting the pressure, the first pressure generated by the expansion member pressurizing the first inner surface is increased as compared with the second pressure generated by the gas pressurizing the second inner surface.

Abstract: A method for manufacturing a joined body according to an embodiment of the present disclosure is a method for manufacturing a joined body in which composite materials in which fibers are impregnated with resins are heated and joined to each other. The method includes: a step of aligning the composite material with each of a plurality of molding dies, heating the molding dies, and semi-curing the resins of the composite materials; and a step of joining the composite materials to each other by combining and heating the molding dies with which the composite materials are aligned after semi-curing the resins of the composite materials. The molding dies used when semi-curing the resins of the composite materials and the molding dies used when joining the composite materials to each other are the same.

Abstract: A waste treatment system, includes: at least one reformer for hydrolyzing waste; a microbial reactor for microbially degrading a reformed material containing at least a solid of the waste hydrolyzed by the at least one reformer; a microbial reaction detection device for detecting a state of degradation of the reformed material in the microbial reactor; and an adjustment device for adjusting amount and timing of supply of the reformed material to the microbial reactor, based on a detected value of the microbial reaction detection device.

Abstract: A waste treatment system includes: at least one reformer for hydrolyzing waste; and a microbial reactor for microbially degrading a reformed material containing at least a solid among the waste hydrolyzed in the at least one reformer.

Abstract: This water treatment system comprises: a reverse osmosis device (2); a biofilm treatment device (4) that has a media on the surface of which a biofilm is formed and that treats water to be treated (3) before passing through the reverse osmosis device (2); an oxidizing agent addition device (5) that adds an oxidizing agent to the water to be treated (3) at a stage before treatment with the biofilm treatment device (4) or adds an oxidizing agent to the water to be treated (3) at a later stage after treatment with the biofilm treatment device (4) and before treatment with the reverse osmosis device (2); and a reducing agent addition device (6) that neutralizes the oxidizing agent by adding a reducing agent to the early stage water to be treated (3) or the later stage water to be treated (3).

Abstract: Provided is a method for manufacturing fiber-reinforced resin materials capable of increasing the stiffness and the strength such as shock resistance by a simple method while suppressing an increase in the product weight. A continuous fiber member 5 including a plurality of continuous fibers is placed at at least a part of a fiber-reinforced resin member 3 including fiber materials 2 mixed into matrix resin 1, followed by pressing, thus impregnating gaps between the continuous fibers making up the continuous fiber member 5 with the matrix resin 1 of the fiber-reinforced resin member 3 liquefied or softened for integration.

Abstract: A plate-like support (2) is provided with a number of accommodating spaces (7) arranged along its surfaces. Two sets of spiral wires (4) are arranged perpendicular to each other, thereby forming a mesh member (5). This mesh member (5) forms the plate-like support (2) having a first surface (2a) and a second surface (2b) between which framework members (6) are disposed. These framework members (6) partition the accommodating spaces (7) so as to envelop them. The accommodating spaces (7) are formed over a space between the first surface (2a) and the second surface (2b), each of which is provided with openings (8), and adjoin the adjacent accommodating spaces (7) through the framework members (6). The framework members (6) are opened to provide communication portions (10), through which the adjacent accommodating spaces (7, 7) communicate with each other.
