Forming method of carbon fiber pipe type piece

Abstract

The invention discloses a forming method of a carbon fiber pipe type piece. The forming of the carbon fiber pipe type piece comprises the following steps that S1, a heat-shrinkable plastic pipe layeris pre-treated, the inner surface and the outer surface of the heat-shrinkable plastic pipe layer are coated with a second isolation layer, and the surface of a mold is coated with a first isolation layer; S2, the carbon fiber material is immersed in a solution in advance, and then paving of the pre-immersed material is carried out; and S3, the pre-sucking process is carried out, under the condition of certain temperature and pressure, a certain amount of resin is sucked from carbon fiber material layer laminated blocks, so that the resin content of the carbon fiber material layer is controlled. According to the forming method, the heat-shrinkable plastic pipe layer is automatically shrunk under the high-temperature condition, meanwhile, the resin of the carbon fiber material layer is softened under the condition of high temperature, the carbon fiber material layer can be uniformly pressed by the shrinkage of the heat-shrinkable plastic pipe layer, so that the resin is flat, the effectof enabling the surface of the workpiece to be smooth is achieved, and the method is suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of carbon fiber tube processing, in particular to a carbon fiber tube molding method. Background technique [0002] Carbon fiber tube, also known as carbon fiber tube, also known as carbon tube, carbon fiber tube, is made of carbon fiber composite material pre-impregnated with styrene-based polyester resin and heated and cured by pultrusion (twisting). In the process of manufacturing, various profiles can be produced through different molds, such as: carbon fiber round tubes of different specifications, square tubes of different specifications, sheets of different specifications, and other profiles: 3K can also be packaged in the production process. Surface packaging beautification and so on. [0003] In the past carbon fiber tube forming method, in the process of processing, the surface of the formed tube will be unevenly pressed and wrinkled. Even, resulting in low demoulding efficiency and high damage r...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a carbon fiber pipe molding method, which solves the problem that the surface of the pipe formed in the background technology will be unevenly pressed and thus wrinkle and uneven. In the past, during the heating and curing process, the resin flowed out. It will cause adhesion between the carbon fiber tube and the mold, resulting in low demoulding efficiency and high damage rate
