Embodiment 1

[0033] like figure 2 , Figure 4 Shown, a kind of preparation technology of stainless steel ultra-thin strip / carbon fiber pipe, it is characterized in that: comprise the steps:

[0034] Step 1. Mandrel processing: process the original mandrel into an invar steel round bar mandrel with a diameter of 30 mm and a length of 500 mm, with a surface finish of 0.8 and a verticality of 0.05 between the end face and the side of the bar mandrel; Threaded holes are processed at both ends to facilitate screwing in the handle for demoulding; the surface of the rod-shaped mandrel is finished to ensure that the surface roughness meets the requirements for applying the release agent;

[0035] Step 2. Surface treatment: Use acetone to clean the surface of the rod-shaped mandrel obtained in Step 1. After it is completely dry, apply a release agent and wrap it with a layer of release cloth;

[0036] Step 3. Cutting component materials: Determine the layer structure from inside to outside as 5 ...

Embodiment 2

[0043] like image 3 , Figure 5 Shown, a kind of preparation technology of stainless steel ultra-thin strip / carbon fiber pipe, it is characterized in that: comprise the steps:

[0044] Step 1. Mandrel processing: process the original mandrel into an invar steel square bar mandrel with a side length of 30mm, a fillet radius of 5mm, and a length of 500mm. The surface finish is 0.8, and the perpendicularity between the end face and the side of the bar mandrel is 0.05; Process threaded holes at both ends of the rod-shaped mandrel to facilitate screwing in the handle for demoulding; finish the surface of the rod-shaped mandrel to ensure that the surface roughness meets the requirements for applying the release agent;

[0045] Step 2. Surface treatment: Use acetone to clean the surface of the rod-shaped mandrel obtained in Step 1. After it is completely dry, apply a release agent and wrap it with a layer of release cloth;

[0046]Step 3. Cutting the component materials: Determine...

Abstract

The invention provides a preparation technology of a stainless steel ultra-thin strip/carbon fiber pipe. The preparation technology sequentially comprises the steps of core mold machining, surface treatment, component material cutting, stainless steel ultra-thin strip surface treatment, gluing, component material wrapping, forming and demolding. The stainless steel ultra-thin strip adopted by the process has good flexibility and is beneficial to curl forming; the strength, the toughness, the thermal expansion coefficient and the like of the pipe are controlled by designing the layering structure of the stainless steel ultra-thin strip and the carbon fiber woven cloth; according to different prepregs used by the carbon fiber woven cloth, corresponding forming treatment forms are selected, so that the carbon fiber woven cloth is toughened, meanwhile, it is guaranteed that the pipe has high strength, and the pipe has good performance in the aspects of stretching, compression, bending, torsion, pipe fitting connection and the like.

Description

technical field [0001] The invention relates to the technical field of carbon fiber composite materials, in particular to a preparation process of a stainless steel ultra-thin strip / carbon fiber pipe. Background technique [0002] Pipes are widely used in many industrial fields, such as pipes for water supply and drainage, pipes for petroleum geological drilling, pipes for mechanical processes, and cushioning and energy-absorbing thin-walled cylindrical structures, etc. The material of the pipe directly determines the quality and use of the pipe . [0003] The main materials of conventional pipes are divided into two categories: metal materials and polymer materials. Among them, carbon fiber composite pipes have the advantages of light weight, fatigue resistance, and corrosion resistance. They have been widely used in equipment shafts, sports equipment, medical equipment and other fields. ; but its shortcomings are also significant, mainly reflected in its overall performan...
