Problems solved by technology

[0002] The ropes in the prior art are generally formed by twisting multiple strands of ropes, and the service life of the ropes is generally judged by an experienced master according to the wear condition of the rope surface, especially the ropes used on the aircraft. However, judging the service life of the rope based on experience, its accuracy is poor, and it is easy to have certain safety hazards. However, the existing ropes cannot be used due to the poor strength of the rope itself and the influence of the use environment. Use under ultra-high temperature or ultra-low temperature conditions, resulting in a short service life

Embodiment 1

[0013] A method for making a polyester-based composite rope described in this embodiment includes the following steps, S1, ingredients: the raw material is composed of the following components in parts by weight: carbon fiber 5-10%, high molecular weight polyethylene 55% -65%, PBO15-20%, aramid fiber 20-30%, in which carbon fiber, high molecular polyethylene and PBO are uniformly mixed by a mixer to form a cable core, and then the raw material aramid fiber is wrapped outside the cable core to form a monofilament; S2. Twisting: Invade the monofilaments into the glue pool for gluing, and then go through the twisting machine for right-hand twisting, and arrange the monofilaments reasonably and evenly on the tension ring of the flange according to the layers, with consistent tension and uniform rotation speed. Form a triangular strand core; S3, rope making: After the triangular strand core is glued, an inner layer composed of 12 steel wires and an outer layer composed of 12 steel w...

Embodiment 2

[0016] A method for making a polyester-based composite rope described in this embodiment includes the following steps, S1, ingredients: the raw material is composed of the following components in parts by weight: 5% carbon fiber, 60% high molecular weight polyethylene, PBO15%, aramid fiber 20%, among which carbon fiber, high molecular polyethylene and PBO are uniformly mixed by a mixer to form a cable core, and then the raw material aramid fiber is wrapped outside the cable core to form a monofilament; S2, twisting: the monofilament Invade the glue pool for gluing, and then use the twisting machine to perform right-hand twisting, arrange the monofilaments reasonably and evenly on the tension ring of the flange according to the layers, and make the triangular strand core at a uniform speed; S3, rope making: put After the triangular strand core has been glued, it is wrapped with an inner layer composed of 12 steel wires and an outer layer composed of 12 steel wires, and then twis...

Abstract

The invention discloses a production method of a polyester-based composite rope. The polyester-based composite rope is produced by, by weight percentage, 5-10% of carbon fibers, 55-65% of high-molecular-weight polyethylene, 15-20% of PBO and 20-30% of aramid fibers. The production method includes: using a mixer to evenly mix the carbon fibers, the high-molecular-weight polyethylene and the PBO toform rope cores, and wrapping the rope cores with the aramid fibers to form monofilaments; soaking the monofilaments into a gum tank to perform gumming, using a twisting frame to perform rightward-rotation lang lay, evenly arranging the monofilaments on a tension ring according to layers, and using uniform rotation speed to produce a triangular strand core; subjecting the triangular strand core togum processing, then wrapping the triangular strand core with an inner strand and an outer strand, and twisting into a rope; using a gumming machine to coat the surface of the rope with a glue protecting layer to obtain the polyester-based composite rope. The production method has the advantages that various parts of the rope cores are tightly combined, the performance of various components are brought into full play, and friction between the rope cores and the outer protecting layer is enhanced.

Description

technical field [0001] The invention relates to a method for making a rope, in particular to a method for making a polyester-based composite rope, and belongs to the technical field of military ropes.
