1. Carbon Fiber Prepreg Overview
Carbon fiber prepreg is carbon fiber fabric that has been pre-impregnated with epoxy resin at controlled ratios. The resin is partially cured (B-staged) to allow for easy handling and layup, then fully cured in an autoclave or oven to achieve optimal mechanical properties.
Key Advantages:
- Consistent Quality: Precise resin content control (typically 35-45%)
- Higher Fiber Content: Up to 65% fiber volume fraction
- Reduced Voids: Superior mechanical properties
- Cleaner Process: No mixing required, reduced waste
- Refrigerated Storage: 6-12 months at -18°C

4. FAQ
Q: What is the shelf life of carbon fiber prepreg?
A: Prepreg has 6-12 months shelf life when stored at -18°C. At room temperature, out-life is typically 1-3 months depending on the resin system.
Q: What’s the difference between prepreg and wet layup?
A: Prepreg offers consistent resin content, higher fiber volume, and superior mechanical properties. Wet layup is more economical but has more variability.
Q: Do you offer free samples?
A: Yes! Impact Materials provides free A4-sized samples (210×297mm) for evaluation. Standard samples ship within 3-5 days via express courier.
