The Art and Science of Carbon Fiber Bicycle Frame Manufacturing
The manufacturing process of carbon fiber bicycle frames is basically the same as that of rims, but there are some differences in some technical details. The whole process can be divided into six parts: material preparation, structural rolling preform, molding, structural gluing, surface finishing and quality inspection.
1. Material Preparation
Firstly, preparing the main material for making the frame, which is a type of carbon fiber prepreg fabric that has been impregnated with resin.
Secondly, cutting it into the size and shape which designed by professional engineers with specific cutting tools based on the shape of each frame.
Finally, the cut prepreg is classified and laid flat according to the requirements for subsequent preforming process.
2. Structural Rolling Preform
The front fork, front triangle and rear triangle of the frame are preformed with carbon fiber composite materials.
According to the precise calculation and design of engineers, the structural components are laminated by specific molds.
Each structural component is corresponding to different types of carbon fabric and the number of layers.
It is worth noting that the front triangle is formed with the most advanced latex air bags, which can withstand higher air pressure, allowing the inner wall of the frame to become smoother after forming, significantly improving the performance of the product！
3. Molding
The structural components are molded under a high temperature and high pressure of more than 10kg. During this process, the excess resin will be squeezed out.To prevent the product from deformation, the professional cooling treatment will be conducted.
4. Structural Gluing
The corresponding bonding and fixation molds are used to connect the structural components together to form the entire frame.
Attention should be paid to the treatment of the joint parts and the amount of glue applied during this process.
Finally, by covering the bonding positions with carbon fabric and heating curing to complete the entire gluing process.
5. Surface Finishing
The surface of the frame is meticulously repaired and polished to ensure smoothness, and entire frame production process is completed after multiple painting and baking for curing.
6. Quality Inspection
A series of quality checks on the frame will be conducted to ensure that all the indicators of the frame meet the standards, including weighing and calibration.
While each manufacturer may have proprietary techniques, the core process remains consistent with the above description. Nepest is committed to achieving the pinnacle of quality, striving for "Artwork in Road Cycling" without compromise. Experience the distinction in craftsmanship on your next ride!
