ISO 14129 面內剪應力/剪應變反應
ISO 14129 詳述了由 ±45° 張力測試法量測面內剪應力/剪應變之程序，包括面內剪切模數和纖維強化塑膠複合材料的剪切強度。此方法適用於熱固性、熱塑性為基材的積層板，它由單向層和/或單向纖維製成的織物組成。此纖維面向試樣軸 ±45°，接合處對稱並平衡於試樣的中平面。通常試樣需量測應變，以測定平行、垂直，對此我們使用 Expansion Channel Module 來調節、輸出應變。
ISO 14129 敘述如何以 ±45° 拉伸加載一矩形截面所組成的纖維試樣。為測定剪切模數，需要測量平行和垂直於試樣軸的應力。複合材料常用在航太、汽車以及能源應用，所以關鍵是要了解到材料的強度在真實情況下受到多少的影響。例如，為滿足 NADCAP 的要求，我們可以為您提供一個有效的解決方案。
對於此應用，我們建議使用 3300 或 5900 萬用測試儀器並搭配專用的 Bluehill ® 3 軟體模組，由於它可以很容易地與任何其他常見的複合測試應用作配置，如拉伸、剪切、撓曲、壓縮。
我們對於各項測試的材料提供廣泛夾持解決方案，例如楔型、氣動或液壓夾具。此外，我們建議完整地檢閱 ISO 14129 以了解有關您所測試的材料所需夾具及結果要求。
