Problems solved by technology

However, the resin system is the matrix material, which can make the reinforcing fibers intertwined and transmit the load, so there is an optimal ratio of the resin matrix material to the fiber reinforced material, and this ratio mainly depends on the cross-sectional area of ​​the reinforcing fibers, usually reinforced When the fiber exceeds 70%, the reinforcing fibers contact each other and the performance will decrease

Embodiment 1

[0013] First, the carbon fiber is pretreated, subjected to acetone ultrasonication for 5 minutes, and then roughened. Then, the carbon fiber is passed through the glue tank of the hot-melt adhesive film machine equipped with the prepared resin matrix, 30 parts of epoxy resin, 10 parts of methyl tetrahydrophthalic anhydride, and 3 parts of toughening agent. Evenly transfer the resin to the release paper, so that the prepared film is continuous, uniform and flat, with an area density of 37±3g / m.

[0014] Then, 60 parts of 500k carbon fibers are flattened and soaked with an adhesive film to make a prepreg with an area density of 210±10g / m (the mass of fiber in the area density is 160g / m), and the temperature of the prepreg is 75°C , The prepreg pressure is 0.3MPa, the prepreg running speed is 1.0m / min, and the precuring is 1.5h.

[0015] The impregnated carbon fiber tow is twisted by a twisting machine at a twisting speed of 15n / m, and cured for 1h. The twisted tow is coated wi...

Abstract

The invention provides a method for manufacturing a special carbon fiber rope, and belongs to the field of high polymer materials. The method includes the steps that 500k carbon fibers are firstly preprocessed through acetone ultrasounds and then coarsened, wherein impurities on the surface of the carbon fibers are removed, the superficial area of the carbon fibers is increased, the surface is coarsened, and the combining force between the carbon fibers and epoxy resin is increased; gum dipping is carried out on the preprocessed carbon fibers, and precuring is carried out for 1.5 hours; curing is carried out 1 hour again after twisting is carried out through a twisting machine, stranding is carried out after coating processing is carried out, and the special carbon fiber rope is manufactured. The strength of the special carbon fiber rope is about 10,000 MPa and is about ten times that of a steel cable, the density is about 150 g / m<2>, and the resin content is about 30%. The manufactured carbon fiber rope is mainly used for the oil-gas exploration field.

Description

technical field [0001] The invention relates to a preparation method of a special fiber cable for oil and gas exploration, which is mainly used in the field of oil and gas exploration. Background technique [0002] Due to the dwindling oil reserves, some oil companies have begun to exploit oil in ultra-deep deposits, and the drilling depth sometimes exceeds 1500m. At such depths, the steel pipes traditionally used to anchor oil production platforms have reached their limits, so carbon fiber cables can be used instead. The invention prepares a special carbon fiber cable by using a prepreg method and is applied to oil and gas exploration. [0003] At present, more than 70% of advanced composite products are made of prepreg layup and curing. Prepreg is the intermediate material of advanced composite materials, and it is the basic unit of composite material structure; the mechanical and chemical properties of composite materials depend to a large extent on the intrinsic qualit...
