Problems solved by technology

[0003] The present invention aims to solve the problem that the metal chains in the prior art are heavy and difficult to operate. At the same time, in the marine environment, due to the large amount of ions in the seawater, electrochemical corrosion is prone to occur when the seawater contacts the metal, which reduces the strength of the metal chains and even affects problem of use

specific Embodiment approach 1

[0028] Specific implementation mode one: see Figure 1-3 This embodiment will be described. The forming method of the composite material continuous fiber chain described in this embodiment specifically includes the following steps:

[0029] (1) Prepare continuous fiber reinforced material, the matrix resin of the fiber reinforced material includes epoxy resin system, vinyl ester system and polyester resin system; the reinforcing phase material of the described fiber reinforced material is carbon fiber, glass fiber, aramid fiber One or more of fiber, basalt fiber and PBO fiber;

[0030] (2) Assemble the composite material chain forming mold;

[0031] (3) Wrap the fibers used on the thread guide;

[0032] (4) Use the wire guide to pull the fiber, so that the fiber is tightly wound on the surface of the arc-shaped cavity formed after the mold is assembled, until the fiber fills the arc-shaped cavity of the mold, and the resin is soaked during the winding process, so that the r...

Abstract

The invention provides a forming method of a composite material continuous fiber chain. A related structure applicable material is a fiber reinforced resin matrix composite material. Matrix resin of the composite material comprises an epoxy resin system, a vinyl ester system, a polyester resin system and the like. A reinforced phase material of the composite material comprises continuous fibers such as carbon fibers, glass fibers, aramid fibers, basalt fibers and PBO fibers. The specific method comprises the steps that a chain forming mold is combined, a composite material chain is formed through the continuous fibers, surface finishing is conducted, and the composite material chain of the continuous fibers can be formed through the method. The problems that in the prior art, a metal chain is large in weight and not easy to operate, in the marine environment, due to the fact that seawater contains a large number of ions, electrochemical corrosion is prone to occurring when the seawater makes contact with metal, the strength of the metal chain is reduced, and use is affected are solved. Compared with the metal chain, the composite material chain formed by the forming method is light in weight and easy to operate, and corrosion resistance in the marine environment is good.

Description

technical field [0001] The invention relates to a molding method of composite material continuous fiber chains, and belongs to the technical field of composite material molding methods. Background technique [0002] At present, the material of the chain is metal, such as steel, aluminum and the like. Due to the high density of metal, metal chains are heavy and difficult to handle during use. At the same time, in the marine environment, metals have poor corrosion resistance. Therefore, it is necessary to develop chains of new lightweight materials to replace them. Continuous fiber-reinforced resin-based composites have been widely used in aerospace, transportation, chemical and machinery manufacturing due to their good corrosion resistance, high specific strength and high modulus, but there is no continuous fiber molding of composite materials. Patents and reports on the chain structure. Contents of the invention [0003] In order to solve the problem that the metal chain...
