1、 Overview of Carbon Fiber Winding Forming Process

The winding molding process forms a multi-layer structure on the core mold by controlling the tension, angle, and resin content of carbon fiber yarn. After curing, remove the core mold or keep it as part of the component, suitable for producing pipelines, pressure vessels, and shaft components. This process combines the advantages of automation and material optimization, and is an important means of lightweight design

프로세스 특성

• 높은 효율성: Suitable for mass production of rotating symmetrical components
• Strength optimization: The fiber winding angle can be adjusted according to the force requirements
• 높은 재료 사용률: reduces waste and lowers costs
• High degree of automation: Precise control achieved through equipment

2、 Process flow of carbon fiber winding forming

이 프로세스에는 주로 다음 단계가 포함됩니다:

1. Core mold preparation

Select or make a suitable core mold (usually metal or soluble material) and ensure its surface is smooth for winding and demolding

2. Fiber winding

After impregnating the carbon fiber yarn through a resin tank, it is wound at a specific angle (usually 0 ° to 90 °) on the core mold. The winding machine controls the fiber path and number of layers according to the design program

3. Curing process

After winding, place the core mold in an oven or at room temperature to cure, and the resin hardens to form a stable structure. The curing time depends on the resin type and component thickness

4. Demoulding and precision machining

After curing, remove the core mold (if it is a soluble core mold, dissolve it), trim, polish or coat the components to meet the final requirements
