スター，ラダー，フィンスタビライザー等や海洋構造物
用として使用される構造材に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to structural materials used for stars, rudders, fin stabilizers, etc. and marine structures.
船舶用および海洋構造物用にプラスチツクやＦ Ｒ ■
・（繊維強化プラスチツク）を連片する場合，一般的に
耐海水性を考慮した表面処理が必留てあり，従来は次の
様な処理が行われていた。Plastics and FR ■ for ships and offshore structures
・When making continuous pieces of (fiber-reinforced plastic), it is generally necessary to perform surface treatment that takes seawater resistance into consideration, and conventionally the following treatments were performed.
すなわち、船舶および海洋構造物を構成するグラスチッ

いた。In other words, in order to improve the compatibility with the antifouling paint applied to the surface of the glass and F RPO that make up ships and offshore structures, a biter yaw l- is provided, and the antifouling paint is applied on top of it. , it had seawater resistance.
ところが、このような従来の処理ではプロペラ，バウス
ラスター等の耐キャビテーション性を要求される用途に
対しては，潰食を起こすため使用出来ない上，防汚塗料

出来す。However, such conventional treatments cannot be used for applications that require cavitation resistance such as propellers and bow thrusters because they cause erosion, and antifouling paints and binder coats cannot be used for applications that require cavitation resistance, such as propellers and bow thrusters. Intrusion can be prevented.
最終的には，構造物を構成しているプラスチツクやＦＲ
Ｐに海水が侵入し，このために、プラスチツクやＦＲＰ

Seawater intrudes into P, which causes plastic and FRP
The disadvantage was that the durability deteriorated.
本発明は上記のような欠点を解消することを目的として
提案するもので，従来のプラスチツクやＦ Ｒ Ｐの替
りに，炭素を含んだフがラスチノク又はＣｉＦＲＰ （
炭素繊維強化プラスチツク）を使用して導電性を持たせ
，この導電性を利用して表面に銅又は一合金を電気メン
キするものである。The present invention is proposed with the aim of solving the above-mentioned drawbacks, and instead of conventional plastics and FRP, carbon-containing fibers are used such as Rustinok or CiFRP (
This method uses carbon fiber-reinforced plastic (carbon fiber reinforced plastic) to make it conductive, and uses this conductivity to electrically coat copper or an alloy on its surface.
すなわち、本発明は炭素含有プラスチツク又は炭素繊維

−ｔしてなることを特徴とする耐海水性構造Ａ２である
。That is, the present invention applies copper or copper alloy to the surface of carbon-containing plastic or carbon fiber-reinforced plastic by electromechanical method.
-t is a seawater resistant structure A2.
本発明によれば電気メンキする銅又は銅合金の種類によ

できる。According to the present invention, depending on the type of copper or copper alloy to be electro-etched, it is possible to obtain a 11'G steel material with good seawater resistance that can prevent erosion due to cavitation or adhesion by marine organisms.
次に２本発明を具体的に説明する。Next, two aspects of the present invention will be specifically explained.
炭素繊維強化プラスチックからなるプロペラと炭素粉末

。When the surfaces of a propeller made of carbon fiber-reinforced plastic and a ballast star made of plastic containing carbon powder were electroplated with two layers of aluminum bronze and copper, a good all-B'i FJ was formed. after that,
As a result of using this propeller and barrasque in seawater, there was no erosion due to cavitation or the presence of marine life.
海水のａ入もみられなかった。才だ耐久性も向上した。No intrusion of seawater was observed. The durability has also been improved.
