Core Technical Advantages of SERECARBO®
SERECARBO® combines high-precision fiber-spreading technology with a special high-speed curing resin, offering the following three key technical advantages:
1. Uniform Fiber Spreading Technology
High-precision fiber spreading ensures that each carbon fiber bundle is evenly separated, eliminating issues such as uneven fiber distribution. This process lays the foundation for subsequent resin impregnation, significantly improving the uniformity and stability of material strength.
2. Special High-Speed Curing Resin
A methyl methacrylate resin system is used, offering both ultra-fast curing and stability at room temperature. This resin enables rapid curing in as little as 30 seconds, greatly surpassing the curing speed limits of traditional thermosetting resins. Additionally, the product can be stored at room temperature without freezing or special conditions, effectively reducing storage and management costs.
3. Uniform Impregnation Technology
Using a film-coating process, the resin evenly impregnates each fiber, ensuring consistent overall material performance and avoiding localized weak areas, thereby enhancing product reliability.
