EXPERIMENTAL STUDY ON THE TENSILE MECHANICAL BEHAVIOR OF KEVLAR49 FIBRE BUNDLES UNDER DIFFERENT STRAIN RATES

More Information
  • Received Date: July 28, 1997
  • Revised Date: March 10, 1998
  • The experiments on Kevlar49 fibre bundles under quasi static tension and tensile impact were performed in MTS810 and Bar Bar Tensile Impact Apparatus, respectively. The stress strain curves of Kevlar49 fibre bundles were obtained at strain rates ranging from 10-4 /s to 103/s. The test results show that the mechanical behavior of Kevlar49 fibre bundles is rate dependent. Compared with glass fibre bundles, the rate sensitive degree of Kevlar49 fibre bundles is higher in the quasi static loading region, while it is less great in the high rate loading region.
