With the widespread application of high-performance materials in aerospace, automobiles, rail transit, sports equipment and new energy, carbon fiber composites have become one of the core structural materials in advanced manufacturing with their excellent specific strength, specific modulus, corrosion resistance and design flexibility. In practical applications, the performance of carbon fiber composites depends not only on their processing technology, but also on the scientific selection of raw materials. This article will conduct a systematic analysis of the selection of raw materials in carbon fiber composites to help companies achieve dual optimization of performance and cost in the design and manufacturing stages.
Carbon fiber precursors mainly come from two sources: polyacrylonitrile (PAN)-based and asphalt-based. PAN-based carbon fiber has become the most widely used type due to its good comprehensive properties and is suitable for high-strength structural parts. Asphalt-based carbon fiber has higher thermal conductivity and modulus and is often used in thermal conductive structures and electromagnetic shielding. Users should clarify their own application scenarios before purchasing and choose the appropriate source of precursor.
Carbon fibers come in a variety of forms, including filaments, chopped fibers, unidirectional fabrics, plain fabrics, twill fabrics, etc. If the strength requirement is extremely high, it is recommended to give priority to unidirectional prepreg tapes; if the structural complexity and impact resistance need to be enhanced, woven fabrics are often used. If you need to purchase high-quality carbon fiber cloth or raw yarn, it is recommended to contact professional carbon fiber material supplier Revolve CF (www.revolve-cf.com).
The interfacial bonding ability of carbon fiber and resin directly affects the overall performance of the composite material. Different surface treatment methods (oxidation, plasma treatment) and the type of impregnation agent on the fiber surface must be highly matched with the selected resin system to achieve good adhesion and interlaminar shear strength.
Thermosetting resins (such as epoxy resins, polyester resins, and phenolic resins) are currently the most commonly used matrix systems in carbon fiber composites. Epoxy resins are widely used in aerospace and automotive manufacturing due to their high strength, high modulus, excellent weather resistance and thermal stability. When selecting a suitable epoxy system, attention should be paid to indicators such as curing temperature, impact resistance and long-term thermal stability.
In recent years, thermoplastic resins (such as PEEK, PA, PP, etc.) have gradually emerged in the field of carbon fiber composites. They have the advantages of recyclability, rapid prototyping, and chemical corrosion resistance, and are suitable for large-scale, short-cycle industrial applications. In projects with high environmental requirements or requiring heat-weldable processes, thermoplastic matrices have natural advantages.
When matching raw materials, it is necessary to ensure the compatibility of fiber surface treatment with the resin system used to avoid interface debonding due to surface tension mismatch or polarity difference. As a mature carbon fiber material supplier, Revolve CF can provide customers with complete material selection and matching recommendation services.
Curing agent (such as amines, anhydrides) is an indispensable component in the epoxy resin system. Its type and proportion directly affect the mechanical properties and heat resistance of the final product. In practical applications, customizing the curing system according to the product thickness, curing temperature and target application is the key to optimizing performance.
In applications with high safety requirements such as transportation and building structures, flame retardants have become an important part of the resin system. Common additives include phosphorus, bromine, and inorganic hydroxides. Users can choose the appropriate solution according to industry standards. For outdoor applications, adding anti-UV aging agents is also particularly critical.
A certain proportion of inorganic fillers (such as silica powder) or thickeners (such as PYRODINE, etc.) must be added in the production of prepregs to control the fluidity and glue content of the resin. Although these materials account for a small proportion, they have a profound impact on processing performance and product quality.
When purchasing carbon fiber materials in batches, it is necessary to pay attention to the consistency and traceability of raw materials. The good performance of small batch samples does not represent the stable performance in the mass production process. It is recommended to choose a carbon fiber material supplier with a systematic quality management system, such as Revolve CF, which has many years of R&D and supply experience in the field of carbon fiber and release materials.
Different projects have specific requirements for the strength, modulus, resin system and even woven structure of raw materials. Excellent suppliers should have flexible customization capabilities and be able to provide integrated technical services such as composite structure design, supporting resin system, and release agent selection.
The strength of the supplier can be judged by checking whether it has passed ISO, ROHS, REACH and other system certifications, or whether it has provided supporting services to international leading companies. For example, Revolve CF has provided high-performance carbon fiber solutions to many multinational manufacturing companies and has a good reputation in the industry.
The performance of carbon fiber composites begins with material selection. Whether it is the raw fiber morphology, the type of matrix resin, or the additive system and the supplier's service capabilities, they all determine the stability, strength and service life of the final product. In the early stages of the project, procurement personnel, R&D engineers and design teams should communicate in depth about material requirements and make scientific selections based on actual usage scenarios and processing conditions.
