Summary: | To provide a method for measuring out-of-plane wrinkles of a composite laminate.SOLUTION: The method includes scanning a first side of a composite laminate with an ultrasonic transducer. The method further includes locating the out-of-plane wrinkles of the composite laminate in the B-scan ultrasound image 600 generated in response to scanning the first side of the composite laminate. The method further includes associating a first marker determined based on the location of the top portion of the out-of-plane wrinkles in the B-scan ultrasound image to the B-scan ultrasound image 600. The method further includes associating a second marker determined based on the location of the concave focal point of the out-of-plane wrinkles in the B-scan ultrasound image in the B-scan ultrasound image. The method further includes determining a variation range 902 of the out-of-plane wrinkles on the basis of the distance between the first marker and the second marker.SELECTED DRAWING: Figure 9
【課題】複合積層板の面外皺(out−of−plane wrinkles)を測定するための方法を提供する。【解決手段】超音波トランスデューサで複合積層板の第1の側をスキャンすることを含む。この方法は、複合積層板の第1の側をスキャンすることに応じて生成されるB−スキャン超音波画像600において、複合積層板の面外皺を位置特定することを更に含む。方法は、B−スキャン超音波画像600に、B−スキャン超音波画像における面外皺の頂部の場所に基づいて決定される第1マーカーを関連付けることを更に含む。方法は、B−スキャン超音波画像に、B−スキャン超音波画像における面外皺の凹部焦点の場所に基づいて決定される第2マーカーを関連付けることを更に含む。方法は、第1マーカーと第2マーカーとの間の距離に基づいて、面外皺の変動幅902を判定することを更に含む。【選択図】図9 |
