Our company has successfully developed a trial batch of 80T asphalt-based carbon fiber prepreg, taking a crucial step forward in high-end composite materials

Recently, our company's R&D team successfully developed a trial batch of 80T high-strength, wear-resistant pitch-based carbon fiber prepreg through continuous technological breakthroughs. According to testing by an independent third-party authoritative institution, the product's performance indicators meet international advanced standards for similar products. This marks a significant breakthrough for our company in the field of high-performance carbon fiber composites and injects new momentum into achieving self-reliance and control over critical materials for China's high-end manufacturing industry.

The 80T pitch-based carbon fiber prepreg is a high-end composite intermediate material developed as a key focus of our company. It uses high-strength pitch-based carbon fibers as the reinforcement and combines them with a special resin system featuring excellent adhesion, manufactured through an advanced continuous hot-melt process. This product delivers outstanding overall performance: tensile strength reaches up to 3000 MPa, tensile modulus exceeds 780 GPa, and wear resistance is improved by over 40% compared to conventional 55T series materials. At the same time, it offers lightweight and high-rigidity characteristics—its density is only about 40% that of traditional metal materials. Additionally, it exhibits exceptional dimensional stability after curing and extremely low thermal expansion coefficient, enabling dimensional deviation control within 0.3% even under harsh conditions such as high temperature and high-frequency friction.

 In terms of the molding process, this prepreg material has excellent laydown properties and process compatibility, enabling it to flexibly meet the requirements of various molding methods such as compression molding and autoclave molding. This effectively addresses the long-standing problem of insufficient compatibility between imported high-end prepregs and domestic equipment.

As a strategic key basic material, the application prospects of 80T asphalt-based carbon fiber prepreg are extremely broad. With outstanding characteristics such as high strength, high modulus, wear resistance, and high temperature resistance, this product can be widely applied in high-end brake pads, motor carbon brushes, and precision structural components, which all have extremely high requirements for material wear resistance and dimensional stability. At the same time, it also has significant application value in strategic emerging industries such as aerospace, semiconductor equipment, and high-end equipment manufacturing.

The successful trial production of this 80T asphalt-based carbon fiber prepreg is another significant achievement for our company in adhering to independent innovation and deepening its research and development in high-performance composite materials. The company will take this as an opportunity to accelerate the mass production and market promotion of the product, and continuously contribute the strength of the enterprise to the high-quality development of China's new materials industry and the domestic substitution of key materials.
