Pultrusion and winding are both important forming processes for fiber materials. The pultrusion process can produce products with light weight, corrosion resistance and low conductivity, which are suitable for mass production. It was originally used to produce glass fiber composite materials. With the development of technology, it is gradually used in carbon fiber and Kevlar fiber. Now, both civilian and industrial products of carbon fiber can be manufactured by this method. It has penetrated into many fields such as transportation, sporting goods, medical equipment and so on.
Pultrusion consists of three sequential, continuous automated processes, preforming of reinforcement material, resin infusion of the molded body and conversion of the preform into a solid layer and board peak resin curing. These three processes can be seen as three independent technical steps. The first stage is the formation of carbon fiber bundles with a properly oriented structure, and the second stage is the impregnation of the resin into the fiber preform. These two stages can be performed in parallel, saving time. The third stage is to complete the setting, curing and forming the final solid part in the heat setting mold. The whole process is affected by conditions such as tensile force, thermal expansion coefficient, and temperature. The pultrusion equipment itself is not an important factor in determining the success of machining and forming, it can be any kind of machinery that can realize clamping and drawing to make the material pass through the above three processes.
This article is just about telling you about the pultrusion technology of carbon fiber. China Be-cu official website will continue to update other content about carbon fiber, you can always pay attention to our website to check, if you need carbon fiber materials, you can find China Be-cu Carbon Fiber Composite Materials Co., Ltd.
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.
