引言

超聲檢測試塊主要分為兩種類型，一種是用以評定和校準超聲檢測設備，具有規(guī)定的化學成分、表

面粗糙度、熱處理及幾何形狀的標準試塊；一種是與試件或被檢材料聲學特性相似、含有意義明確參考

反射體、用以調節(jié)超聲檢測儀的幅度和（或）時基線，以將所檢出的不連續(xù)信號與已知反射體所產生的

信號相比較的對比試塊。

當對比試塊用于調節(jié)超聲檢測儀的幅度和（或）時基線，并與所檢出的不連續(xù)信號相比較時，試塊

內部設置意義明確的參考反射體；當對比試塊僅用于調節(jié)超聲檢測儀的幅度和（或）時基線時，采用對

比試塊底面作為參考反射體，即內部不含參考反射體的階梯對比試塊；對比試塊也可僅用于與所檢出

的不連續(xù)信號相比較，從而獲得檢測閾值，如對樹脂基復合材料制件內部孔隙進行超聲檢測與評價時

所使用的孔隙率對比試塊。

目前，復合材料廣泛應用于體育器材、汽車制造、船舶重工及航空航天等領域。其中樹脂基復合材

料是最為成熟、應用最為廣泛的一類復合材料。但由于樹脂基復合材料中的基體材料和增強材料種類

繁多、制造成型工藝多樣，導致材料的聲學特性差異較大，檢測過程無法采用標準試塊，因而直接采用

對比試塊。

本文件充分考慮到已獲得穩(wěn)定應用的樹脂基復合材料超聲檢測對比試塊參考反射體的制作方法，

包括內埋法、邊緣插片法、外貼法、平底孔法以及其他特殊方法，明確樹脂基復合材料超聲檢測對比試

塊要求，規(guī)范樹脂基復合材料超聲檢測用對比試塊的設計、制作和檢驗方法，指導樹脂基復合材料結構

超聲檢測的實踐。
