Abstract

This study proposes a novel tab for the tensile testing of unidirectional (UD) carbon fiber-reinforced thermoplastic polyamide 6 (CF/PA6) to reduce stress concentration at the tab end. The length of the new tab is identical to that of the UD CF/PA6 specimen to avoid a sudden change in geometry that is typically observed in a conventional tab end. Additionally, three types of UD CF/PA6 laminates from different manufacturers are used to fabricate tensile specimens. Specimens with a new tab and a conventional nontapered tab are tested under quasi-static tension. Finite element simulations of tensile testing are also performed for specimens with two types of tabs. The experimental and simulation results demonstrate that the newly designed tab reduces the stress concentration at the tab end by approximately 10% and improves the estimates of tensile strength for the UD thermoplastic composite laminates.
