Detailed explanation of carbon fiber tube rolling process

Roll Wrapping ist ein fortschrittliches Verfahren zur Herstellung von röhrenförmigen Bauteilen aus Kohlefaser-Prepreg durch Walz- und Wickeltechniken. Es ist in vielen Branchen wegen seines geringen Gewichts, seiner hohen Festigkeit und seiner Designflexibilität sehr beliebt.

1、 Overview of Carbon Fiber Tube Rolling Process

The rolling process involves wrapping carbon fiber prepreg around a core mold and curing it through rolling and heating to produce tubular structures with excellent mechanical properties. This process is particularly suitable for manufacturing bicycle frames, sports equipment, and industrial pipe fittings, as it enables high-precision and consistent pipe production

Prozessmerkmale

Lightweight: Carbon fiber pipes weigh much less than traditional metal pipes

High strength: Multi angle fiber laminates enhance compressive and torsional properties

Customization: Pipe diameter and wall thickness can be adjusted according to needs

Good surface quality: After curing, the surface is smooth and can be used directly

2、 Process flow of carbon fiber tube rolling

Das Verfahren umfasst im Wesentlichen die folgenden Schritte:

1. Pre impregnated material cutting and preparation

According to the design requirements, cut the carbon fiber prepreg to an appropriate width and length, and ensure that the fiber direction meets the mechanical optimization requirements.

2. Winding and Rolling

Wrap the pre impregnated material around the core mold and apply pressure using a rolling tool to ensure that the pre impregnated material is tightly adhered and removes bubbles. The winding angle and number of layers should be adjusted according to the design requirements.

3. Curing process

Place the wound core mold in an oven or hot pressing equipment, and cure the resin by heating (usually 100 ° C to 150 ° C) to form a tubular structure. The curing time depends on the resin type and wall thickness.

4. Demoulding and precision machining

After curing is complete, remove the core mold and trim, polish or surface coat the pipe to meet the final usage requirements.
