Abstract: | Tensile and knot fatigue property of high-performance polyethylene (HPPE), regular polyethylene (PE), nylon multifilament (PAmu), and nylon monofilament (PAmo) under cyclic loading conditions were investigated. The durability of HPPE under tensile fatigue testing was largest, followed by PAmo, PAmu and PE. In knot fatigue, the largest was PAmo, followed by HPPE, PAmu, and PE. High resistance by HPPE to the cyclic loads was also confirmed by scanning electron microscopy, which showed that HPPE suffered the least damage from abrasion compared with the other twines. From the measurement of elongation changes during the cyclic loading, HPPE had very small changes. The low elongation value of HPPE was probably the result of its better fatigue property because there was less damage from abrasion. |
