Abstract
Description
サイズが300mm x 300mm x 3mmのパネルを、オートクレーブ硬化により調製する。パネルの組合せ(layup)は、0/90である。次いで、36mm x 36mmである試験に供する試料(一般的に3〜4個)をパネルから切り出す。試料の正方形の面は、研磨して(例えば、リニッシャー(Linisher)装置で)、炭素繊維を露出させるべきである。硬化時に剥離層を用いる場合には、これは必要ではない。過剰な研磨は、これが最初の層を越えて侵入するので、避けるべきである。次いで、正方形の面をスパッターにより電気伝導性金属、一般的に金の薄層で被覆する。試料の側面の金又は金属はすべて、試験前に研磨によって除去すべきである。低い接触抵抗を保証するために金属コーティングが必要である。
室温における衝撃後圧縮(CAI)試験は、航空宇宙用複合材料の試験の技術分野に精通している者に周知の試験プロトコールに従って実施した。この試験に関する準拠した特定の試験方法は、AITM 1−0010であった。
