Carbon fiber bicycle frames consist of layers of carbon fiber (woven carbon fiber layers) embedded in an epoxy resin matrix. The carbon fiber gives it strength, and the resin binds it together. Most frames are made from multiple layers of carbon fiber/resin material (called "prepreg"), with different grades and directions taken into account at different locations in the frame.
Advantages:
- High stiffness-to-weight ratio;
- Enhanced Formability;
- Capable of being molded into aerodynamic tubular profiles.
