Carbon fiber is widely used in aerospace, infrastructure, electromagnetic shielding, automobile manufacturing, oil exploitation and other fields because of its fatigue resistance, high temperature resistance, high strength, high modulus, conductivity, radiation resistance, small coefficient of thermal expansion and light weight. It has strong designability and various molding methods, including winding, pultrusion, injection, hand paste, molding, etc. This article introduces the molding process of carbon fiber.
Carbon fiber molding steps:
1. Mold cleaning. Clean the mold to avoid the residue of dust and sundries.
2. Apply release agent. After ensuring that the mold is clean and smooth, apply release agent to prevent the product from sticking to the mold after molding.
3. Material preparation. Prepare the required carbon fiber prepreg according to the shape and size of the product.
4. Stack. The carbon fiber prepreg - layers are stacked and preloaded to form a dense entity with regular shape and certain quality.
5. Molding. Put the stacked raw materials into the mold, close the mold, set the pressure, time and temperature, and press at high temperature.
6. Cooling and demoulding. After hot pressing, cool for a period of time, and then open the mold to take out the product.
7. Post processing. The products taken out from the mold are rough, and have to go through a series of post-treatment processes such as trimming, grinding and painting.
In the molding process, special attention should be paid to the three elements of temperature, force and time. Temperature has a decisive influence on the melting, flow and solidification of materials; Pressure can make a layer of carbon fiber prepreg bond more closely; Time can make the product in the mold cavity have enough time to cure.
Compared with the traditional hand paste process, molding: I technology is more advanced, with high dimensional accuracy, which is suitable for mass production. Our company has strong strength, master a variety of molding technologies, and has large hot press, hot press tank, hydraulic molding table and many imported machines
More than ten kinds of processing equipment such as CNC high-speed milling machine can process carbon fiber board, carbon fiber auto parts, carbon fiber mechanical parts and other products for customers according to the drawings.
