以国产UHMWPE纤维为材料,采用八股编绞绳编绞工艺和复合技术,研制了适合大型抗风浪养殖网箱技术和使用要求的UHMWPE复合绳,并对其性能进行了测试。结果表明,绳索的平均断裂强度为PA绳的3.7倍、PP绳的4.0倍。绳索经氨酯基树脂复合后断裂强力平均提高8%,断裂强度达9.89～13.2cN/dtex,伸长率为5.5%～9.1%。绳索拉伸疲劳性能为加载循环2400次后的强力保持率仍达100%。高强度、低伸长、抗疲劳复合绳索的研究结果,可为养殖网箱等海洋工程配套设计、安全使用等提供技术依据。
Taking UHMWPE fiber as material, UHMWPE composite ropes suitable for large-scale wind-resistant cage breeding and using requirements were developed by using octant braided strands braiding technology and composite technology, and their performances were tested. The results showed that the average breaking strength of ropes was 3.7 times that of PA ropes and 4.0 times of PP ropes. The average breaking strength of the ropes by urethane resin increased by 8%, the breaking strength reached 9.89 ~ 13.2cN / dtex and the elongation was 5.5% ~ 9.1%. Tensile fatigue properties of ropes are still up to 100% after 2400 cycles of loading. High-strength, low elongation, anti-fatigue composite rope research results for aquaculture cage and other marine engineering design, safety and provide technical basis.
