Abstract

PURPOSE:To spread an adhesive to all the corners and to carry out firm bonding without letting the adhesive leak from sides of faces to be adhered to the outside by sealing end parts of the faces to be adhered with an O-ring, introducing an adhesive to the faces under pressure, bonding the faces while evacuating space from the other part. CONSTITUTION:A small hole 11a is connected to a vacuum pump 13 and space formed by an inner peripheral face 11c at the end part of a cylinder 11 and an outer peripheral face 12a of a bottom plate 12 is evacuated by the vacuum pump. On the other hand, an epoxy-based adhesive 14 is introduced under pressure from a storage container 15 through a small hole 11b to faces to be adhered of the cylinder 11 and the bottom plate 12. An O-ring 17 is supported and fixed on both faces of peripheral parts of the bottom plate 12 by a pedestal 18. The O-ring 17 is arranged in such a way that the O-ring covers the bonded part of the bottom plate and one end of the cylinder when the bottom plate 12 is engaged with one end of the cylinder 11.

方法としては、接着面をコルゲート構造が採用される。(Prior Art) Conventionally, in low-temperature containers for storing cryogenic fluids such as liquid helium, FRP, which has lower thermal conductivity than metal, has been used.
Structures such as fluid storage vessels and vacuum vessels may be formed by this process. When manufacturing such a structure using FRP, it is necessary to bond the FRP materials together. FRP
Epoxy-based adhesives are usually used to bond the materials. This adhesion requires strength as a pressure vessel and high sealing performance against gas leaks. As a bonding method that provides strength, a corrugated structure is used for the bonding surface.

圧入する方法を用いている。That is, by adopting the corrugated structure, there is always a portion where the adhesive thickness is about 0.2 to 0.3 mm, so that the adhesive strength is maximized. On the other hand, in order to improve the sealing performance, the adhesive should be sufficiently filled so that no residual gas remains on the adhesive surface. For this purpose, a method is used in which the joint space is evacuated in advance and the adhesive is press-fitted through the hole.

るという欠点もあった。(Problems to be Solved by the Invention) When an adhesive is press-fitted into a joint using the conventional press-fitting method described above, there is a drawback that the press-fitted adhesive may leak out from the side surface of the joint. Another drawback was that if adhesive leaked into the cryogenic container, the adhesive would cover the superconducting coil housed inside, impairing cooling of the coil and causing quenching.

In a method of manufacturing a structure by adhering FRP materials to each other by press-fitting and bonding, by press-fitting and bonding the adhesive with the adhesive surface end sealed with an O-ring, This solves the above drawbacks.

It is press-fitted into the bonding surface between the cylinder 11 and the bottom plate 12 via 1b. O-rings (indicated by 17 in FIG. 2) are supported and fixed on both sides of the peripheral edge of the bottom plate 12 by a pedestal 18.
