本発明は、内面がセラミックや金属で強化された繊維強
化樹脂管の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for manufacturing a fiber-reinforced resin pipe whose inner surface is reinforced with ceramic or metal.
繊維強化樹脂管は金属管に比べて軽量であるため、軽量
化の要望される種々の用途に使用されるようになってい
る。しかし、繊維強化樹脂管は、金属に比べて耐摩耗性
や耐熱性に劣るため、例えばアブレイシブな物体を輸送
する管とか、加熱物体を輸送する管に対しては制約があ
った。Since fiber-reinforced resin pipes are lighter than metal pipes, they have come to be used in various applications where weight reduction is desired. However, since fiber-reinforced resin pipes have inferior abrasion resistance and heat resistance compared to metals, there are restrictions on their use as pipes for transporting abrasive objects or heated objects, for example.
このような制約を解消するため、繊維強化樹脂管の内面

ガンによって溶射膜を施せるのは、溶射ガンのアームが
挿入できる範囲内に限られ、長尺な管に対して不可能で
あった。また、溶射ガンの挿入ができないような小径の
繊維強化樹脂管に対しても溶射膜の形成は不可能であっ
た。In order to overcome these limitations, it has been proposed to thermally spray ceramic or metal onto the inner surface of a fiber-reinforced resin tube to impart wear resistance and heat resistance. However, the thermal spraying gun can only apply a thermal spray coating within the range into which the arm of the thermal spray gun can be inserted, and it has been impossible to apply a thermal spray coating to long pipes. Furthermore, it has been impossible to form a thermal spray film on a small-diameter fiber-reinforced resin pipe into which a thermal spray gun cannot be inserted.
また、上記溶射膜の形成は、溶射ガンを繊維強化樹脂管
の中に盲の状態に挿入して行うため、その溶射膜の厚さ
が不均一にならざるを得ないという欠点があった。Furthermore, since the above-mentioned thermal spray coating is formed by blindly inserting a thermal spray gun into a fiber-reinforced resin pipe, there is a drawback that the thickness of the thermal spray coating inevitably becomes non-uniform.
本発明の目的は、上述した従来の問題を解消し、管の長

の製造方法を提供することにある。The purpose of the present invention is to solve the above-mentioned conventional problems and to manufacture an inner-faced fiber-reinforced resin pipe that can form a uniform sprayed coating of ceramic or metal regardless of the length or thickness of the pipe. The purpose is to provide a method.

を離脱させることを特徴とするものである。To achieve the above object, the present invention forms a thin film of fiber reinforced resin on a mandrel, sprays ceramic or metal onto this thin film to form a film, and further coats the main body of fiber reinforced resin on top of this sprayed film. The method is characterized in that the mandrel is removed after forming the layer.

等の熱硬化性樹脂が好ましく使用される。In the present invention, the fiber-reinforced resin refers to a resin mainly reinforced with filament-like long fibers.The type of long fibers is not particularly limited, but commonly used fibers such as aramid fibers, carbon fibers, glass fibers, and boron fibers are used. You can apply whatever you have. Furthermore, the resin reinforced by the long fibers is not particularly limited, but thermosetting resins such as epoxy resins, phenol resins, and unsaturated polyester resins are preferably used.
本発明において繊維強化樹脂管の内面強化のために使用
されるセラミックや金属の種類は特に限定されないが、
内面強化用のものであるため繊維強化樹脂よりは耐摩耗
性や耐熱性に優れたものであることが好ましい。In the present invention, the types of ceramics and metals used for reinforcing the inner surface of the fiber-reinforced resin pipe are not particularly limited, but
Since it is used to strengthen the inner surface, it is preferable that it has better abrasion resistance and heat resistance than fiber reinforced resin.
第１図〜第３図は、本発明によって繊維強化樹脂管を製
造する場合を工程順に示したものである。FIGS. 1 to 3 show the manufacturing process of a fiber-reinforced resin pipe according to the present invention in the order of steps.
まず、第１図に示すようにマンドレル１を回転させつつ
、その上に繊維強化樹脂による薄膜２を下地として形成
する。First, as shown in FIG. 1, while rotating a mandrel 1, a thin film 2 made of fiber reinforced resin is formed as a base thereon.

。This fiber-reinforced resin thin film 2 is not the main body of the fiber-reinforced resin pipe, but serves as an intermediate medium for forming a thermally sprayed film of ceramic, metal, etc., which will be described later, so it is best to keep it as thin as possible. Preferred, preferably thickness 0.1
The mandrel 1 is preferably made of metal such as steel and has a cylindrical shape. Since this mandrel affects the precision of the fiber reinforced resin pipe, it is preferable to use one that has been precisely processed.
上述のようにマンドレル上に薄膜２を形成したら、次い

、薄Ｈ！Ｉ２の外側から行うので、製作する繊維強化樹
脂管の長さや太さに無関係に実施することができ、また
外側から行うので、均一な膜形成を行うことができる。After forming the thin film 2 on the mandrel as described above, the ceramic or metal thermal spray gun 4 is moved back and forth along the rotation axis direction while rotating the mandrel 1 as shown in FIG. A sprayed film 3 is formed by spraying atomized ceramic or metal onto the surface. This thermal spraying operation is thin H! Since it is carried out from the outside of I2, it can be carried out regardless of the length and thickness of the fiber-reinforced resin pipe to be manufactured, and since it is carried out from the outside, it is possible to form a uniform film.
溶射膜３が形成されたら、第３図のように、マンドレル

。この繊維強化樹脂層５は、上記繊維強化樹脂の薄膜２
とは異なり繊維強化樹脂管の本体部分となるので、必要
な厚肉にする必要がある。After the sprayed film 3 is formed, as shown in FIG. 3, the fiber reinforced resin layer 5 is formed by filament winding and lay-amping on the sprayed film 3 without rotating the mandrel 1. This fiber-reinforced resin layer 5 consists of the fiber-reinforced resin thin film 2
Unlike this, it is the main body of the fiber-reinforced resin pipe, so it needs to be as thick as necessary.
繊維強化樹脂層５を形成したら、最後にマンドレルｌを
引き抜いて多層からなる繊維強化樹脂管Ｐを完成する。After forming the fiber-reinforced resin layer 5, the mandrel I is finally pulled out to complete the multilayer fiber-reinforced resin pipe P.

膜３と薄膜２が形成された繊維強化樹脂管Ｐが得られる
。That is, a fiber-reinforced resin pipe P is obtained in which the thermal sprayed film 3 and the thin film 2 are formed inside the thick tubular fiber-reinforced resin layer 5.

射膜を均一にすることも容易にできる。As described above, according to the manufacturing method of the present invention, the thermal spray coating is applied from the outside, so no matter how long the fiber-reinforced resin pipe is or how thin the diameter is, the thermal spray coating on ceramic or metal can be applied. can be formed. Further, the sprayed film can be easily made uniform.

し支えない。In addition, in the present invention, the thin film of fiber-reinforced resin formed on the mandrel is formed as an intermediate medium to prevent the sprayed film from adhering to the mandrel and to enable good release of the mandrel. When used in transportation pipes, etc., there is no problem if the material detaches and disappears during the use process.

溶射膜にすることができる。As described above, according to the present invention, in order to form a ceramic or metal sprayed film by operating from the outside of the fiber-reinforced resin thin film formed on the mandrel, the fiber-reinforced resin pipe is attached to the arm of the spray gun. Even if the diameter is so long that the spray gun cannot reach it, or the diameter is so thin that the spray gun cannot fit into it, a sprayed film can be formed regardless of these conditions, and a uniform sprayed film can be obtained.
