| Abstract: |
| The characteristic of domestic para-aramid fiber as skeleton material were introduced.The effect of twist on bending properties of domestic para-aramid fiber were studied.The results shown that：with the twist increased, the tensile strength and the hook strength increased at first, and then decreased; the hook strength higher than the tensile strength at low twist; the knot strength unchanged, and lower than the tensile strength; the tensile elongation at break increased; the hook elongation at break and the knot elongation at break unchanged, and both lower than the tensile elongation.The breaking mechanism was discussed。 |
