Abstract
【解決手段】 試験体の一側に設けた送信子20(21)から超音波を送信すると共に同側の受信子30(31)で反射波を受信する。送信子及び受信子と試験体100との間の気層を介して超音波を送受信する。反射経路RBにおける反射波の伝播時間tbよりも送信子及び受信子間の気中経路RAの気中伝播時間taが長くなるように送信子20、受信子30及び試験体100の相対位置を設定する。さらに、送信子及び受信子間の固体を介した超音波の伝播を遮断する。本発明は、例えばCFRP101とインシュレーション102との貼り合わせのような積層材料100を非接触で試験するのに適している。

著者松原重行他 非破壊検査協会 平成13年度終期大会講演概要集 エア・カップリングによるCFRP材料の超音波探傷 p213−214
前記送信子及び受信子の対向部に遮蔽体を設けることで、気中伝播経路の距離を実質的に延長し、送信子及び受信子をより近接させることが可能となる。
様々な深度の検査対象部に対応させるためには、送信子及び受信子をそれぞれフレームに揺動可能に支持するとよい。
本発明は、CFRPとインシュレーションとの貼り合わせのような積層材料を試験する場合に好適に実施できる。
図3は本発明に係る超音波試験装置1を示し、この超音波試験装置1はパーソナルコンピューター(PC)2により制御されるバースト波発生装置5を用いてスキャンヘッド10の送信子20から超音波を送信し、受信子30を介して受信された超音波をプリアンプ6,フィルタ4、A/D3を介してPC2に受信し、処理を行う。また、PC2はドライバ7を介してスキャナ8を駆動させ、スキャンヘッド10により試験体100の表面を二次元的にスキャニングする。
ta=16(mm)/0.340(mm/μs)=47.1μs
一方、反射経路RBの伝播時間tbは
tb=5(mm)×2/0.340(mm/μs)
+15(mm)×20.5×2/2.78(mm/μs)=44.7μs
