Carbon Fiber Compression Molding Process


The seemingly inconspicuous carbon fiber is actually a dark horse in the prototype material industry. Carbon fiber is only one-tenth the thickness of a hair, and its tensile strength can reach 7-9 times that of steel, but its weight is only 1/4 of the dry weight. , so carbon fiber products have been applied in many fields. Molding is the main molding process of carbon fiber products. In this article, let’s take a look at the molding of carbon fiber products.
First, the mold needs to be cleaned to ensure it is clean and tidy, and then a layer of release agent is applied to the mold, and then the cut carbon fiber prepreg can be attached to the mold. The mold is sent to the press and cured at high temperature. The products produced by the molding process have a high carbon fiber content, very few carbon fibers that are not infiltrated by resin, and the surface of the product is smooth and flat, and the strength retention rate is high.
In compression molding, the temperature determines the heat transfer of the mold to the material, and has a great influence on the melting, flow and solidification process of the material. The pressure can close the mold tightly and densify the material, which ensures the flow of the melt and balances the pressure generated by the volatilization of the material in the cavity. The length of time is an important indicator to ensure curing.
China Be-cu Prototype Material Technology Co., Ltd. is a manufacturer that develops and manufactures carbon fiber components such as rail transit, automotive industry, , medical equipment, etc. The company’s products are made of well-known brand raw materials from Taiwan and Japan, and are committed to bringing customers High quality carbon fiber products.

Carbon Fiber Compression Molding Process

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%.
