How Pressure Affects Carbon Fiber Molding
Carbon fiber molding is a commonly used molding process for carbon fiber products. Carbon fiber prepreg is attached to the molding mold. After the mold is closed, the desired carbon fiber product is made by adjusting the pressure, temperature, and time. The pressure affects the effect of carbon fiber molding. With a larger role, we will take a look at it together in this article.
First of all, let’s understand the function of pressure. The pressure in molding is mainly used to overcome the vapor pressure generated by volatile substances in the material, which can avoid defects such as delamination, bubbles, and loose structure of the product. At the same time, the pressure can also make the material The fluidity is enhanced, which is convenient for the material to fill the mold, and the obtained product is more precise and strong.
In the carbon fiber molding process, there are certain requirements for the time of applying pressure. If the pressure is applied too early, the degree of cross-linking reaction of the material will be low, and the fluidity will be enhanced, which will cause serious material loss, easy accumulation of resin, and local lack of glue. , which will cause part of the fibers to be exposed. However, if the pressure time is delayed, the cross-linking reaction degree of the material is high, the fluidity becomes poor, and it is not easy to fill the mold, and the quality of the obtained carbon fiber product will also decrease. At the same time, for some products with larger thickness, an appropriate increase in pressure is beneficial to forming.
China Be-cu Prototype Material Technology Co., Ltd. was established in 2005. It has a production workshop of more than 5,000 square meters. It is a powerful manufacturer of carbon fiber products. It has large hot presses, autoclave tanks, hydraulic forming tables, CNC high-speed Milling machines and other equipment, insist on bringing two high-quality carbon fiber products to customers.
ISO 9001 certified. BE-CU Prototype Offering CNC machining carbon fiber and other manufacturing services for carbon fiber marterial. Various capabilities include notching, labeling, drilling carbon fiber, grinding, laser cutting carbon fiber, finishing, plating, marking, CNC milling carbon fiber and turning carbon fiber.We stock high quality 3k carbon fiber sheet in a variety of thickness, types and finish. Its a great material used in applications where light weight and strength are needed such as drones. Unlike other workshops, we have no min order and are often filling orders with a single part. We also don’t make you pay for the full sheet and you only get charged for what is used. With a large selection of material, you should find everything you need to make your project come to life. We are also able to handle larger production runs and provide a competitive pricing. If we don’t have the material or finish you require, we are more the willing to look at bringing it in for you.
What Is Carbon Fiber?Carbon fiber is made of polyacrylonitrile (PAN) (or pitch, viscose) and other organic fibers by carbonization (removal of most elements except carbon) by pyrolysis method under inert gas at high temperature above 1,000 °C. Inorganic polymer fibers with a carbon content of more than 90%.
