经编双轴向复合土工布的结构与性能

The Structure and Property of the Bi-Axis Warp-Knitting Geocomposites

介绍了经编双轴向复合土工布的结构、生产工艺和性能 .在对其结构研究和分析以及将其力学性能与机织复合土工布的力学性能进行比较的基础上 ,发现经编双轴向复合土工布具有较高的初始模量、较低的断裂伸长率、很高的撕裂强度和很高的纱线潜能利用率 .

The structure, knitting processing and property of the bi-axis warp-knitting geocomposites are presented. Based on the analysis of the structure of the bi-axis warp-knitting geocomposites as well as the comparison of the mechanical property between weaven geocomposites and bi-axis warp-knitting geocomposites, it is found that the bi-axis warp-knitting geocomposites has a higher initial Young's modulus, lower rupture elongation, higher tear resistance and a higher percentage of usable yarn potenitial. The influnce of the structure and knitting processing on the hydraulic property is indicated as well.
