Embodiment Construction
[0015] Below in conjunction with example, further illustrate the present invention.
[0016] The auxiliary materials used in the examples are commonly used epoxy resin fixation time regulators, toughness and product strength regulators, and their dosage and proportion are well known to those skilled in the art.
[0017] 1) Preparation of component A: Take 6 parts of high-performance cycloaliphatic epoxy resin, 3 parts of phenolic resin, 0.5 part of whisker powder coagulant, and 0.5 part of auxiliary materials, and disperse with a high-speed disperser;
[0018] 2) Preparation of component B: take 4 parts of tung oil, add 1 part of auxiliary materials to the tung oil, react at 200°C to form tung oil resin, then add 5 parts of high-temperature anhydride resin, and disperse with a high-speed disperser;
[0019] 3) Mix 50% each of the two components of A: B, mix evenly, transfer to the sizing hopper, and set aside;
[0020] 4) Unwind and straighten the carbon fiber bundles for the...

Abstract
The invention discloses a manufacturing method of a carbon fiber composite core, which comprises the following steps that: carbon fiber bundle for an inner core and external carbon fiber bundle are uncoiled and are dried and preheated by a drying box; then the fiber bundles are soaked by resin, and the fiber bundles after being soaked are concentrated through a thread guide and a yarn collector; the resin is heated to change from in a liquid state to be half-solidified until to be in an adhesion state, and the fiber bundles are compressed and preformed; the preformed fiber bundles are compressed through an adjusting passage, so the air inside the fiber bundles is discharged, and the fiber-resin ratio is adjusted, and the fiber bundles are primarily concentrated to form a small fiber bundle; and the small fiber bundles are further concentrated and compacted, an inner carbon core is firstly concentrated to a bundle, then a glass fiber bundle is compounded outside the inner carbon core bundle to be compacted, heated and solidified, and the fiber bundles are wound to store after being cooled after being recooled, reheated and secondarily solidified. The product manufactured with the method has light weight, high strength and good weather resistance; the product can bear the high temperature of less than 200 DEG C for a long time and can bear the high temperature of less than or equal to 250 DEG C in a short time; and the surface of the product is smooth and bright, and the performance is excellent.
Description
technical field [0001] The invention relates to a method for manufacturing a composite fiber, in particular to a method for manufacturing a carbon fiber composite core for power transmission lines. Background technique [0002] In the existing high-power aluminum strands, it is often necessary to compound steel cores in the middle of the aluminum strands to increase the strength of the aluminum strands and meet the needs of long-distance spanning. [0003] However, the steel core is heavy in weight and low in strength, and the strength will be further weakened at high temperature, which is not conducive to the long-term use of aluminum stranded wire. For this reason, people have developed the FRP composite core to replace the steel core. Although the weight is reduced, the strength is still insufficient. The reason is that there are defects in the manufacturing process. Contents of the invention [0004] In order to solve the above problems, the present invention provide...
