Abstract

The invention discloses a flat coiling type wire winding method of carbon fibers and a carbon fiber rod machining process based on the method. The flat coiling type wire winding method comprises the following steps of raw material wire standby application, unit winding, knot solidification and the like. The carbon fiber rod machining process comprises the following steps of raw material wire layer preparing, polyacrylamide coating, film coating vacuum treatment, high-pressure rolling fusion treatment and high-temperature solidification treatment. According to the flat coiling type wire winding method of the carbon fibers and the carbon fiber rod machining process based on the method, wires are used for replacing cloth, and the strength and hardness of the carbon fibers can be achieved fully; through the arrangement tightness degree in the winding process, the degree of tightness of the carbon fibers can be adjusted at any time according to outer stress; meanwhile, the automatic stress adjusting function of a fishing pole is achieved, elasticity is improved, but the strength and hardness are not influenced; and the flat coiling type method is used for first knots and second knots high in stress.

Description

[0001] Technical field: [0002] The invention relates to a flat-rolled carbon fiber winding method and a carbon fiber rod processing technology based on the method. [0003] Background technique: [0004] Nowadays, two types of carbon fiber materials are often used to make high-end fishing rods on the market, one is referred to as T type and the other is referred to as M type. The carbon content of T-type carbon fiber materials is generally about 75%, and the resin content is about 25%. It has good stretch and toughness functions. The defect is that the content of resin is too high, which causes its hardness to decrease and weight. The M-type carbon fiber cloth contains about 85% carbon and 15% resin. It has good hardness and light weight. However, due to the low resin content, its toughness and stretching effect are greatly reduced. In addition, carbon fiber has a smooth surface, high inertness, and few chemically active functional groups, resulting in low bonding strength between...

Problems solved by technology

The carbon content of T-shaped carbon fiber materials is generally about 75%, and the resin content is about 25%, which has good tensile and toughness functions. The defect is that the hardness decreases and the weight is heavy due to the high content of resin.

M-type carbon fiber cloth contains about 85% carbon and about 15% resin. It has good hardness and light weight. However, due to the low resin content, its toughness and tensile effect are greatly reduced.

In addition, the surface of carbon fiber is smooth, inert, and has few chemically active functional groups, resulting in low interface bonding strength between carbon fiber and matrix resin, and there are many defects in the interface, which often becomes the weak link of composite materials.

However, the carbon fiber layer is generally arranged in the way of carbon fiber cloth wrapping, which makes the thickness of the material larger, but the strength has not reached the desired level, and the existing technology has no solution for this.
