薄膜的拉伸測試,符合 ASTM D882 / ISO 527-3 標準
[00:00:05] 演講者: ASTM D882 和 ISO 527-3 是用於測量薄膜拉伸特性的常用測試標準。
[00:00:14] 演講者: 由於這些材料的薄型特性,準確測量試樣尺寸至關重要。
[00:00:20] 演講者: 試樣長度和寬度取決於預期的伸長率和所需的結果,但通常從 1 英寸寬開始,範圍在 4 到 10 英寸長之間。
[00:00:29] 演講者: 重要的是查閱標準,以驗證您的材料的正確尺寸。
[00:00:34] 演講者:應對三個測量值取平均值,以確定試樣的寬度和厚度。
[00:00:38] 演講者: 數位測微計是用於進行這些測量的合適選擇。
[00:00:43] 演講者: 夾具必須能夠適應試樣隨著測試進行而變薄的情況。
[00:00:48] 演講者: 氣動側向作用夾具是首選的夾持解決方案,因為它們提供一致的夾緊力。
[00:00:54] 演講者: 夾爪面的選擇取決於材料的厚度和強度。橡膠或光滑面是最常用的。
[00:01:01] 演講者: 試樣對齊至關重要,應避免重新插入試樣。
[00:01:07] 演講者: 透過使用對齊和插入裝置(例如 Instron 的精密試樣裝載器),可以提高重複性和產量。
[00:01:15] 演講者: 建議使用引伸計來計算模量結果。
[00:01:20] 演講者: 使用的任何引伸計都需要具有正負 1% 誤差的測量精度。
[00:01:26] 演講者: Instron 的 AVE 先進視訊引伸計是一種非接觸式解決方案,非常適合測量薄膜等精細試樣的應變。
[00:01:36] 演講者: ASTM D882 的關鍵結果包括斷裂應變、制動係數、抗拉強度、屈服強度和屈服伸長率。
[00:01:46] 演講者: ISO 527-3 的關鍵結果包括屈服和斷裂時的標稱應變、屈服時的拉伸應力和斷裂時的拉伸應力。
[00:01:56] 演講者: 雖然本影片希望能提供一些關於此主題的總體見解,但我們始終建議與您當地的銷售工程師聯繫,以討論您的具體需求。
[00:02:05] 演講者: 如需更多資訊,請瀏覽我們的網站或聯絡我們提出任何問題。
[00:02:09] 演講者: 感謝您的收看。

AT3 Automated Film Tensile Testing to ASTM D882
The Instron® TestMaster AT3 Automated Testing System uses an innovative three-axis design for automatic tensile testing of thin films. Normal tensile testing of thin films can prove challenging, but the versatile AT3 makes it easy, improving repeatability, safety, and efficiency by automating everything from measurement to specimen handling and removal.
Precision Specimen Loader for Thin Films and Foils
The precision specimen loader improves alignment and the setup process for testing thin films and foils, resulting in reduced variation in test results and improved safety and ergonomics. Available for our 250 N pneumatic side action tensile grips (catalog no. 2712-052), this device uses a detachable alignment clip and linear rail to guide the specimens into the grips. The precision specimen loader is available in multiple sizes to accommodate a wide range of specimen dimensions.
AT3 Automated Testing System: Configured for Thin Film Testing
The Instron® AT3 Automated Testing System uses an innovative and adaptable design for testing materials such as rigid plastics, elastomers, rubber, thin film, foam, and metals. In this video, the AT3 is testing separator film for electric vehicle batteries. Normal tensile testing of films can prove challenging, but the versatile AT3 makes it easy, improving repeatability, safety, and efficiency by automating everything from measurement to specimen handling and removal. With a smaller footprint than the AT6 robotic system, the AT3 provides a simple and compact solution while still maintaining high throughput and accuracy.
