How to Produce Carbon Fiber Square Tubes - Carbon Fiber Tube Manufacturing Process
The manufacturing process of carbon fiber square tube roughly includes five steps:
Mold making
First of all, the mold is designed according to the square tube size required by the customer, including the tooling requirements after forming. In addition, a series of conditions of the carbon fiber square tube size should be considered, and the thickness of the reserved tolerance tube should be determined according to the need. In order to ensure dimensional accuracy, we should also pay attention to bending deformation. If the pipe size is large, we need to use high-strength steel mold.
Prepreg cutting
After the mold is designed, the carbon fiber prepreg needs to be cut according to the size, the unidirectional carbon fiber prepreg needs to be stacked at 0 and 90 degrees, and the laying method needs to be determined according to the stress of the carbon fiber products.
Blank forming
After the prepreg and mold are completed, the prepreg shall be filled. Put the carbon fiber prepreg layer by layer on the mold, and compact the prepreg to ensure that the resin flows inside after mold closing. The closer the interior of carbon fiber products, the better the performance of finished products. When installing the mold, it is also necessary to apply a release agent to facilitate demoulding.
Heating and solidifying
After the mold is completed, put the carbon fiber blank on the hot press, and complete the curing of the carbon fiber square tube under the action of temperature and pressure. During the manufacturing process, it is necessary to pay attention to the changes in forming temperature and time parameters. The manufacture of carbon fiber square tubes is closely related to temperature, pressure, and time. After molding, pressure and heat preservation should be maintained.
Demoulding
The carbon fiber square tube is taken out by the demoulding equipment. After demoulding, it is taken out and put into the molding machine. After demoulding, the mold needs to be cleaned before repeating the above steps.
Comparison Between Carbon Fiber Tube and Aluminum Alloy Tube
Weight: Carbon fiber tubes are lighter than aluminum alloy tubes, although both are relatively light, but the weight reduction effect of carbon fiber tubes is more obvious.
Strength: The tensile strength of carbon fiber tubes is also higher than that of aluminum alloy tubes, making carbon fiber tubes more advantageous when subjected to high stress loads.
Corrosion resistance: Both carbon fiber tubes and aluminum alloy tubes have some corrosion resistance, but carbon fiber tubes usually do not require additional anti-corrosion treatment.
Processing performance: The processing performance of carbon fiber tubes and aluminum alloy tubes is relatively good, but carbon fiber tubes require special processes and equipment.
Applications: Carbon fiber tubes are more common in applications requiring extremely high strength and lightweight (such as aerospace), while aluminum alloy tubes are widely used in aerospace, automotive, construction and other fields.
Custom Carbon Fiber Tubes
Carbon fiber composite pipe is a more common and typical application form of carbon fiber products. This kind of pipe parts shows many advantages such as light weight, high strength, corrosion resistance, small creep, fatigue resistance, and even energy absorption and shock resistance. It is widely used in intelligent machinery, rail transit, high-end medical and other fields.
What should be paid attention to in the customization of carbon fiber composite pipes?
Drawings must be accurate
Whether it is a heterosexual part or not, carbon fiber products need to be customized. On the one hand, because the raw materials and production costs of carbon fiber products are expensive, there is generally no finished product to stock up, on the other hand, because parts such as carbon fiber pipes need to be combined with other The components are assembled and used, so the carbon fiber pipe seems simple and needs to be customized, and the parameters must be accurate.
For the basic parameters of carbon fiber pipes such as inner diameter, outer diameter and length, they must be precise and accurate. When determining the parameters, it is necessary to consider whether the performance of the finished product meets the standard, and to achieve the advantage of lightweight as much as possible to ensure that the finished product is suitable for assembly.
Select materials to meet performance requirements
From the perspective of reinforcement, there are many types of carbon fiber composite materials. Carbon fiber precursors are different from 1K, 3K, 12K, 24K, and 48K. Weaving angle is divided into plain weave, twill weave, satin weave, two-dimensional, three-dimensional, three-dimensional weaving, etc. Carbon fiber composite materials are anisotropic, that is, there will be certain differences in tensile and bending strength and modulus in different directions. For carbon fiber pipes, the most common plain weave and twill weave have different strengths under tension and torsion.
From the perspective of resin matrix, carbon fiber composite pipes of conventional shapes generally perform better in axial tensile properties, while in terms of compression properties, there are certain differences mainly depending on the type of resin, the greater the strength of the matrix material. , the better the compression resistance of the finished pipe.
Improve the forming process to ensure the performance of the pipe
Different from metal pipes, carbon fiber composite pipes exhibit significant anisotropy because of the different arrangement directions of the reinforcements-carbon fibers. Regardless of whether carbon fiber unidirectional prepregs or woven prepregs are used, different layup directions and layup structures have a direct impact on the final performance of the finished product. Reasonable layup structure design can effectively exert the performance advantages of carbon fiber pipe and prolong the service life of the product. In order to accurately test the performance of carbon fiber composite pipes, it is necessary to fully consider the stress concentration of the composite material and the actual shape and size of the pipe.
Adequate time for customization
Although carbon fiber tubes are conventional parts, every link in the process cannot be omitted or neglected, from mold opening to material selection and layering to later painting and installation of metal parts, etc., every step needs to be fixed. Even in mass production, the entire production cycle will not be greatly shortened. When customizing the carbon fiber tube, it is necessary to leave enough production time for the manufacturer to ensure the performance and quality of the finished product.
Weight: The density of carbon fiber pipes is much lower than that of steel pipes, usually only about 1/4 of steel pipes, so in the same volume, carbon fiber pipes are much lighter. This lightweight property makes carbon fiber tubes a significant advantage in situations where weight reduction is required.
Strength: The tensile strength of carbon fiber tubes is much higher than that of ordinary steel, about 5-9 times that of steel. This means that at the same weight, carbon fiber tubes can withstand greater loads and have higher specific strength.
Corrosion resistance: Carbon fiber pipes have good corrosion resistance and can maintain stable performance under harsh environmental conditions, while steel pipes need anti-corrosion treatment.
Processing performance: The processing performance of carbon fiber pipes is relatively complex and requires special processes and equipment, while steel pipes are relatively easy to process.
Applications: Carbon fiber tubes are widely used in aerospace, automobile manufacturing, sports equipment and other fields, while steel pipes are more used in construction, manufacturing and infrastructure and other fields.
Types of Carbon Fiber Tubes
Standard Modulus Carbon Fiber Tubing (SM)
This is the most common grade of carbon fiber used for our carbon fiber tubes. Standard modulus offers excellent strength and stiffness. It is 1.5X stiffer than aluminum and is the most economical grade.
Intermediate Modulus Carbon Fiber Tubing (IM)
This grade of tubing offers enhanced stiffness over standard modulus carbon fiber tubing with the same or better strength. Intermediate modulus is approximately two times stiffer than aluminum tubing.
High Modulus Carbon Fiber Tubing (HM)
At three times stiffer than aluminum (or equivalent to steel stiffness), this grade of tubing has very similar strength to standard modulus carbon fiber tubing. It is an excellent choice for demanding, weight sensitive applications.
Ultra-High Modulus Carbon Fiber Tubing (UHM)
Incredible stiffness at four-five times that of aluminum or 1.5 times that of steel. Ultra-high modulus has lower strength and is not recommended for high stress applications.
