What Seven Labs Discovered When They Tested the Same Composite, Six Ways
Even when labs follow ASTM and ISO standards to the letter, tensile test results for unidirectional carbon fiber composites can still vary—and the reasons why aren't always what you'd expect. A recent global round-robin study involving seven labs and six coupon designs set out to find the real sources of variability and the results challenge some long-held assumptions about specimen geometry, strain gauge accuracy and sample preparation. In this webinar, Instron will walk you through the study's key findings, what they mean for your own testing practices and how the right tools and methods can help you get more consistent, trustworthy data from every test.
