Description

【発明の詳細な説明】 本発明は、繊維強化プラスチツク管の接合方法に関する
。
従来の管接合方法には、第１図及び第２図に示すような
、ネジ接合方法が使用されている。第１図及び第２図に
おいて、１は繊維強化プラスチツク管、２はネジ接合部
である。この方法はネジ部の機械加工が塑性加工できる
金属の転造等によるネジ加工に比べ、超硬鋼工具、ダイ
ヤモンド工具等の特殊工具による旋盤加工に大半を頼る
ため加工費が非常に割り高となる。
また、繊維強化プラスチツク管のネ／接合には加工時強
化繊維の毛はたち等により、不完全なネジ山を形成した
場合のネジ山同士のガタ（隙間）による管軸方向の強度
（せん断強度）の低下、ノ・ラツキが生じる。
本発明は、ネジ接合方法にかわる、従来、繊維強化プラ
スチツク管同士には適用されなかったし寸りばめはめ合
い管接合方法を採用することにより、その接合部の加工
費を低減し、せん断強度を増大及び安定させる繊維強化
プラスチツク管の接合方法を提供するものである。
本発明は、繊維強化プラスチツク管の外管の内径を繊維
強化プラスチツク管の内管の外径より所定の寸法だけ小
さく加工し、外管を加熱もしくは内管を冷却することに
より両管をはめ合わせて後圧着接合さげることを特徴と
する繊維強化プラスチツク管の接合方法に関する。
本発明において繊維強化プラスチツク管には特に制限は
なく、強化繊維として、ガラス、カーボン繊維等の無機
繊維、ポリエステル繊維、アラミツド繊維等の有機繊維
、ステンレス、ボロン等の金属繊維などを使用し、マト
リックス樹脂として熱硬化性樹脂または熱可塑性樹脂を
用いて得られるものが用いられる。
第３図に本発明の一例を示す。
第３図において、３は強化繊維積層方向を示し４は繊維
強化プラスチツク管の外管、５はその内管、６ははめ合
わせ面を示す。
本発明において外管の加熱は加熱用乾燥器で行われ、内
管の冷却はドライアイス、液体窒素等の媒体を入れた冷
却容器内で行われる。
本発明の接合方法においては、圧着、接合に際して接着
剤を用いてもよい。
本発明の詳細な説明する。

とく、はめ合わせ前に外管４の内径を内管５の外径より
所定の寸法（しめしろ）だけ小さく加工し、はめ合わせ
面をす２４０〜＋６００エメリーペーパーで研摩した。
更に、外管を加熱炉で１５０１ｒに加熱し、炉より取シ
出して常温にてすみやかにはめ合わせ圧着接合させて後
第３図に示す構造の管継手を得た。
第１表に従来のネジ接合方法と本発明の実施例になる接

時間で硬化させた。
第１表におけるせん断力の試験方法は第４図に示すよう
にして常温で行なった。すなわち、定盤８上に接合した
管継手を外管を下側にして配置し、つぎに内管上部に金
属製の押え治具を乗せ、荷重Ｐをかけて、はめ合わせ面

第４図において、４は繊維強化プラスチツク管の外管、
５はその内管、６ははめ合わせ面、７は押え治具、８は
定盤を示す。数字の単位は順である。
第１表に示されるように本発明になる接合方法によれば
、従来のネジ接合方法に比べ、せん断応力が平均で最大
５０チも増大し、またデータのばらつきがネジ接合に比
べ安定している。
本発明になる接合方法は、その接合部の加工費を低減し
、その管継手としての軸方向強度（せん断強度）を増大
改善するものである。
