摘要

Kevlar-29 fibers are being used in different applications due of their exceptional mechanical properties. More mechanical information on these fibers is needed for better understanding of their complex mechanical behavior. This article presents results from tensile tests on single Kevlar-29 filaments, to characterize their intrinsic behavior under quasi-static loading, and nanoindentation tests, to investigate their cross-section mechanical properties. The results reveal that the elastic modulus measured in the fiber cross-section is lower than that obtained in the longitudinal direction due to the high anisotropy of the fibers.
