From resin synthesis, prepreg production to product molding (such as compression molding, autoclave process), Dasen has the complete industrial chain support capability.

Highlights of Carbon Fiber Prepreg Products and Technologies

The carbon fiber prepreg product line of Dasen covers unidirectional prepregs (UD) and fabric prepregs (weave fabric/spread tow fabric), supporting various fiber types (such as T700, T800, M40, etc.) and resin systems. Here are the technical highlights:

High-performance resin matrix

Dasen's resin R&D team has experience in 3C and medical composite materials, and can develop low porosity, high toughness or high-temperature resistant resins according to customer needs, meeting the performance requirements of different application scenarios. Through equipment such as thermal cracking gas chromatography and X-ray fluorescence spectrometer, the resin curing characteristics and interface bonding strength can be precisely controlled.

Precision production process

Online thickness measurement and uniformity control: X-ray thickness gauge monitors the pre-impregnated material thickness in real time, ensuring the stability of the weight (20-200 gsm) and resin content (25-50%).

Fiber low-damage technology: 

Optimizes the unwinding and impregnation processes to reduce the damage to carbon fibers during the processing, enhancing the mechanical properties of the final product.

Innovative application fields

3C electronics: Develop lightweight carbon fiber prepregs for the hinges of foldable phones and the battery covers.

Automotive industry: 

Provide carbon fiber covering solutions for top luxury cars.

Sports equipment and medical devices: 

Mass-produce carbon fiber sports equipment (such as golf clubs, bows and arrows), and collaborate with medical industry clients to develop high-performance composite material components.

Latest R&D Direction and Market Layout

Dasen will focus on implementing the following R&D and market expansion plans in 2025.

Ultra-thin prepreg technology: 

To meet the demands of the consumer electronics sector, we have developed ultra-thin carbon fiber prepregs with a thickness of less than 0.1mm, balancing strength and flexibility.

Thermoplastic prepreg (CFRTP): 

A continuous fiber-reinforced thermoplastic composite material layout to meet the rapid prototyping demands of the automotive market.

Globalized capacity expansion: 

The manufacturing center in Vietnam further enhances its production capacity to meet the customer demands in the Southeast Asian market.

Industry Competitiveness Analysis

The differentiation advantages of Dasen are as follows.

Vertical integration capability: 

Full-chain control from resin synthesis to product molding, shortening the product development cycle for customers.

High-standard quality control: 

The cleanroom production and automated testing equipment ensure product consistency, meeting the strict standards of the 3C electronics and medical industries.

Customer Customization Services: 

The overseas support teams (such as in the United States and South Korea) provide localized technical support and respond promptly to customer needs.

Future Outlook

As the penetration rate of carbon fiber in fields such as new energy vehicles and low-altitude economy increases, Dasen plans to expand the pre-impregnated material production capacity in 2025 and accelerate the combined application of UHTD (ultra-high performance) graphite products and carbon fiber. Additionally, the company will continue to invest in the research and development of continuous fiber 3D printing materials to promote innovative applications of composite materials in intelligent manufacturing.

Conclusion:

Dasen, through in-depth technological development and global expansion, is gradually becoming a leading enterprise in the carbon fiber prepreg industry. Its innovations in resin formulations, production processes, and application development not only accelerate the process of replacing imported high-end composite materials with domestic products, but also provide more competitive lightweight solutions for global customers. In the future, with the growth of green manufacturing and intelligent demand, Dasen is expected to achieve greater breakthroughs in the field of carbon fiber composite materials.
