This mold for prepreg lamination includes a first surface only having a surface flat along one direction; second surfaces having a surface flat along the one direction and disposed at a predetermined angle with respect to the first surface; and a third surface with a cross-sectional shape, which is a surface yielded from a cut in an orthogonal direction to the one direction, that is an arc, and with one end side connected to the first surface and the other end side connected to the second surface. First bend sections having a protruding shape are formed on the second surface and the third surface and serve as boundaries, and one of the surfaces is slanted relative to the other surfaces. On the third surface, the diameter of the arc on the other surface becomes gradually smaller as further away from the first bend section along the one direction.

The method for producing an assembly is a method for producing an assembly equipped with a member to be reinforced (), a reinforcing member body (), and a filler (), wherein the reinforcing member body () has a pair of flanges () arranged spaced on the surface (B) of the member to be reinforced (), a web (), and a connection portion () which connects the flanges () and the web () and forms a filler space (V) with the surface (B). The method for producing an assembly includes a step for inserting a filler () into the filler space (V), a step for attaching a crack control member () to cover the end of the filler (), a step for joining the flanges () and the member to be reinforced (), and a step for curing at least the member to be reinforced ().

Method for producing assembly, reinforcing member, and assembly

Manufacturing structure using a composite material includes: a tapering step for forming a first tapered surface on a first stiffener in an uncured state; a bending step for bending the stiffener such that a second surface is on the inner side; an arranging step for arranging the first stiffener and a skin at prescribed positions; a vacuum suctioning step for vacuum suctioning the first stiffener and the skin; and a bonding step for curing the first stiffener to bond the first stiffener and the skin. In the tapering step, the angle formed between the first tapered surface and the second surface is an acute angle. In the vacuum suctioning step, the first tapered surface is brought into contact with the skin while maintaining contact between the first surface and the skin, and the first stiffener is deformed so that a second tapered surface is formed on the second surface.

A sealant applying apparatus includes a fastener rotating unit which supports a fastener to be rotatable around a central axis, and a sealant discharging unit which applies a sealant to the fastener by discharging the sealant. The fastener rotating unit includes a first holding member and a second holding member which hold the fastener to be rotatable, and a base which supports the first and second holding members. The first holding member is installed to the base to be exchangeable.

Sealant applying apparatus and sealant applying method

A sealant forming nozzle is disposed to seal an object that a sectional shape in a first plane is a stair shape. The sealant forming nozzle includes a shaping section and a guide section. The shaping section includes a shaping surface orthogonal to the first plane, and a sealant output hole to supply a sealant to a space surrounded by the object and the shaping surface. The guide section has a guide surface. The guide surface is orthogonal to the first plane and formed to have a line contact with a corner section of an upper step of the stair shape.

This fastener driving device is equipped with an impact force applying device that repeatedly applies impact forces to a fastener; and a load cell that detects a reaction force acting on the impact force applying device. The impact force applying device stops the applying of the impact force to the fastener on the basis of a detection result of the reactive force.

In a method of fastening composite material parts, a first smoothness of a first fastener is measured which is arranged to a first countersink through-hole which is formed in a first fastened work as stacked composite material parts. A second countersink depth is determined based on the first smoothness. A second countersink through hole with a second countersink depth is formed in a second fastened work as the composite material parts. The second fastened work is fastened using the second fastener arranged to the second countersink through-hole.

Fastening method of composite material parts

A condenser that restrains fluctuations in the condenser vacuum in a power generating installation. In particular, the condenser has a circulating path through which cooling water flows; a tube nest for condensing steam from a steam turbine with the cooling water; and a discharge path. Additionally, a bypass tube; a control valve for controlling the flow rate of the cooling water supplied from the circulating path to the discharge path; a recirculating path; and a booster pump that controls the flow rate of the cooling water are provided. One of the temperature, the flow rate and both the temperature and the flow rate of the cooling water to flow through the two tube nests is deviated from the temperature and the flow rate of the cooling water on the upstream side of the circulating path using the control valve and booster pump.
