Example Embodiment
[0031] Example 1
[0032] A lightweight rigid self-lubricating composite rope with a breaking strength of 180kN and a diameter of 24mm is produced by the following steps:
[0033] 1) Rope design: The diameter of the rope is 24mm and the overmolded layer is 2mm. The diameter of the rope before overmolding is 20mm, the aromatic braided sheath is 2mm, and the diameter of the rope core is 16mm. Calculated based on 80% of HMPE yarns, the total diameter of the yarns is 12.8mm, and the design number of yarns is 30;
[0034] 2) Preparation of rope yarn: add 15 twists / m to 20-in 1500D ultra-high molecular weight polyethylene fiber multifilament, half of the forward direction and half of the reverse direction;
[0035] 3) Preparation of the rope core: thread the 30 rope yarns from the inner layer to the outer layer on a rope twisting machine according to the structure of 3+6+9+12. The first layer of 3 ropes rotates in the positive direction, and the second layer The 6 rope yarns rotate in the ...

[0039] Example 2
[0040] Make a lightweight rigid self-lubricating composite rope with a breaking strength of 198kN and a diameter of 20mm, which is achieved through the following steps:
[0041] 1) Rope design: The diameter of the rope is 20mm and the overmolded layer is 1mm. The diameter of the rope before overmolding is 18mm, the aromatic braided sheath is 1mm, and the diameter of the rope core is 16mm. Calculated based on 70% of HMPE yarns, the diameter of the yarns is 13.3mm, and the design number of yarns is 36;
[0042] 2) Preparation of rope yarn: add 10 twists / m to 20-to-1500D ultra-high molecular weight fiber multifilament;
[0043] 3) Preparation of rope core: 36 rope yarns are threaded on a rope twisting machine according to the structure of 3+6+12+15 from the inner layer to the outer layer. The first layer of 3 ropes rotates in the positive direction, and the second layer 6 rope yarns rotate in the reverse direction, the third layer 12 rope yarns rotate in the forward d...

[0047] Example 3
[0048] A lightweight rigid self-lubricating composite rope with a breaking strength of 33kN and a diameter of 10mm is produced by the following steps:
[0049] 1) Rope design: the diameter of the rope is 10mm, the overmolded layer is 1mm, the diameter of the rope before overmolding is 8mm, the aromatic braided sheath is 1mm, and the diameter of the rope core is 6mm. Calculated based on 90% of HMPE yarns, the total diameter of yarns is 5.8mm, and the number of designed yarns is 11;
[0050] 2) Preparation of rope yarn: add 20 twists / m to 10 in 1500D ultra-high molecular weight fiber multifilament;
[0051] 3) Preparation of the rope core: thread 11 rope yarns from the inner layer to the outer layer according to the 3+8 structure on the rope twisting machine. The first layer 3 rope yarns rotate in the positive direction, and the second layer 8 rope yarns According to reverse rotation, the rope output speed is 0.2m / min, the speed of the rope twisting machine is 20r / mi...
