From raw material to finished product: understand every step of the carbon fiber manufacturing process, including weaving, prepregging, molding, and quality inspection.
Introduction
Carbon fiber manufacturing is a complex, multi-step process that transforms raw polyacrylonitrile (PAN) fibers into high-strength, lightweight composite materials. This guide walks through each stage of production at YongXian CarbonFiber.
Manufacturing Steps
| Step | Process | Temperature |
|---|---|---|
| 1 | Oxidation | 200-300°C |
| 2 | Carbonization | 1000-2000°C |
| 3 | Surface Treatment | Ambient |
| 4 | Sizing | Ambient |
Quality Control
- Tensile strength testing
- Modulus measurement
- Density verification
- Visual inspection
Frequently Asked Questions
How long does carbon fiber manufacturing take?
The complete process from raw PAN fiber to finished carbon fiber typically takes 24-48 hours depending on the grade and specifications.
What grades of carbon fiber do you manufacture?
We produce T700, T800, M40, and M55J grades, each optimized for different strength and modulus requirements.
